ULTRA SOUNDS 

› CONTACT ULTRA-SOUND SURVEYS 

(Direct – Indirect – Semi-direct method) 

The method is based on the propagation 

speed of longitudinal ultra-sonic 

waves inside a reinforced concrete 

structure. The propagation speeds depends 

on the characteristics of the material 

such as elasticity, density, presence 

of gaps, micro-holes, etc… From 

the determination of the following parameters: 

reflection, refraction, transit 

time (T.O.F.) and mitigation of the vibration 

energy, it is possible to obtain information 

on: 

• Homogeneity of the mix 

• Elasto-mechanical characteristics 

• Entity, geometry and location of particular 

faults or internal defects, variations 

in time of the quality parameters 

of the concrete 

Ultra-sonic tests through which it is 

possible to evaluate the transit speed 

of the pulses (with known thickness 

and time) are particularly important. 

The primary goal of the Ultra-sound 

survey is to record the time of fly (TOF, 

Time of Fly) and the following calculation 

of the speed. In order to calculate 

the propagation speed of longitudinal 

waves (P waves), the arrival of the first 

wave-train must be found out with accuracy. 

In order to perform this operation 

correctly, the instrument must be 

equipped with oscilloscope that allows 

to visualize the transit wave on the device 

display. 

The ultra-sound tests can be carried 

out with: 

• Direct method 

When the transmitting and receiving 

probes are positioned on the opposite 

sides of the element to test. 

• Semi-direct method 

When the E/R probes are positioned on 

adjacent surfaces, usually orthogonal, 

of the element to test 

• Indirect method 

When E/R probes are positioned in the 

same side of the structural element to 

test. 

› CROSS-HOLE ULTRA-SOUND TEST 

The cross-hole is a method to analyze 

the foundation poles of buildings that, 

with the use of ultra-sounds, crosshole, 

allow to carry out an accurate 

high resolution test. An ultra-sonic 

wave is sent from a transmitter to 

a receiver, which are convoyed automatically 

by the device along the entire 

length of the pole inside the pipes 

embedded inside of it, during casting. 

The speed of the sonic wave and its 

energy are strongly influenced by the 

quality of the cement. Therefore, it is 

possible to assess the characteristics 

and give a tomographic representation 

in 2D and 3D called diagraphy..

› Mae 9 

› SONIC TEST ON MASONRY 

The principle of the sonic tests on masonry 

is the same as principle of ultrasound 

tests on concrete. The only difference 

is the method to produce the 

longitudinal elastic wave used for the 

measurement: a hammer is used instead 

of an ultra-sonic pulse. The frequencies 

thus produced (a few hundreds 

of Hz), lower than those of the 

ultra-sounds (a few tens of KHz) are 

able to also cross scarcely compact 

masonry walls, such as brick-faced 

or brick walls, thus allowing to evaluate 

the conservation state, through 

the speed and/or mitigation values of 

the wave produced. This type of test 

can also be applied on concrete structures, 

which sizes do not allow to use 

ultra-sounds, because these can no 

longer be measured at a few metres 

from the source. The sonic tests give 

less accurate values compared to the 

tests with ultra-sounds, but they can 

be performed also on scarcely compact 

materials and/or at a distance of 

a few metres. 

› PILE INTEGRITY TEST 

The sonic echo test is a survey method 

consisting in the measurement 

of the reflection speed of compression 

waves, to assess the integrity of 

a pole. The method was conceived in 

Holland during the 70s, as instrument 

to check the quality of pre-fabricated 

foundation poles in concrete, extensively 

used in that country. Due to the 

regularity of the surfaces of the prefabricated 

poles, the sonic echo test 

could be used with a high level of reliability. 

For this type of test, a compression 

wave is propagated until the base 

of the pole and is reflected towards its 

head. The compression wave is generated 

with an impact on the pole head 

and the signal recorded by a geophone 

is displayed in a graph in real time. If 

discontinuities are present in the pole 

such as variations of the section or 

cracks, these cause reflections. If the 

discontinuities are fairly significant, 

such as for example a complete fracture 

of the concrete, these cause an 

almost complete fracture, thus preventing 

to detect the base of the pole. 

In order to execute the test properly, 

the pole head must be accessed. The 

geophone is placed on the concrete 

surfaced, properly prepared, through 

a coupling material and by placing 

on top a load of a few kg. When the 

head of the pole is hit in a selected 

point, the impact enables the acquisition 

of the signal produced by the geophone, 

which is shown immediately on 

the screen. In order to eliminate the 

background noise caused from the 

construction site activities, the acquisition 

can be repeated a few times to 

calculate the averages.

SUPPORTED INVESTIGATION 

Ultrasonic contact test 

Digital instrumentation for ultrasonic 

tests through transparency, it can 

be used for testing walls, trusses, 

partition walls, specimen, laboratory 

samples, and other types of concrete 

structures or stony materials. 

The extremely compact sizes render 

I-SONIC suitable for particularly burdensome 

uses, where utmost accuracy 

in the measurement is required, 

together with reliability, sturdiness 

and compact sizes. Thanks to the 

presence of a large graphic display, 

the visualization and interpretation 

of the data acquired is easy and immediate. 

Each single wave emitted 

by the internal generator is visualized 

in full and it is also possible to 

modify the visualization parameters 

to further facilitate the reading of 

the crossing speed. The data is saved 

on a removable S.D. memory. 

The ultrasonic test through contact 

is a standardized system in the diagnostics 

sector of concrete structures. 

From the analysis of the compression 

waves P in the material, it is possible 

to obtain the transit time (airborne 

time T.O.F.), of the ultrasonic waves 

in the material and the transmission 

speed of the same waves inside the 

material tested. The use of this method 

at high frequencies is particularly 

suitable for compact materials, as 

hardened concrete, and on structural 

elements of reduced sizes, such as 

beams, pillars, etc… 

This series of instruments allows to 

assess the mechanical characteristics 

of the materials, evaluate the 

degree of homogeneity and possible 

presence of holes, gaps, defects or 

building anomalies of the element.

Instrumentation for the execution of 

non-invasive surveys of sonic and ultrasonic 

type with an electro-mechanical 

hammer operating on concrete structures, 

masonry and on various types 

of building materials on site and in the 

laboratory. The extensive spectrum of 

incoming frequencies analysed, allows 

to take measurements on materials 

with different mechanical, compactness 

and homogeneity characteristics. 

The ultrasonic test through transparency 

is a standardized system in the 

diagnostics sector of concrete structures. 

From the analysis of the compression 

waves P in the material, it 

is possible to obtain the transit time 

(airborne time T.O.F.) of the ultrasonic 

waves in the material and the transmission 

speed of the same waves inside 

the material tested. The use of 

this method at high frequencies is 

particularly suitable for compact materials, 

as hardened concrete and on 

structural elements such as trusses, 

partition walls, or other types of 

concrete structures or stony materials 

with good aggregation degree. 

The sonic surveys are carried out using 

an electro-mechanical hammer 

that acts as trigger and a receiving 

probe. Waves on the material to inspect 

are generated on the trigger 

hammer, which are then detected by 

the receiving probe and recorded in 

the central unit. The sonic method is 

extensively used in tests of materials 

with scarce propagation characteristics, 

non-compact and heterogeneous 

materials in which the distances to 

travel are fairly high and they cannot 

be reached with the ultra-sonic system 

at other frequencies. A5000UM 

allows to assess the mechanical characteristics 

of the materials, evaluate 

the degree of homogeneity and possible 

presence of holes, gaps, defects 

or building anomalies of the element. 

Masonry structures, brick-faced walls, 

historic and monumental buildings 

can be assessed in terms of conservation 

state, in a quick and easy manner, 

limiting as much as possible the execution 

of destructive tests. Thanks to 

the presence of a large graphic display, 

the visualization and interpretation of 

the ultra-sonic waves generated is 

easy and immediate, the first reading 

can be picked and the speed and quality 

values of the material tested can 

be read directly on the device display. 

Each single wave emitted by the internal 

generator is visualized in full and 

it is also possible to modify the visualization 

parameters to further facilitate 

the reading of the crossing speed. 

The data is saved on a removable S.D. 

memory.

A3000U device is a complete system 

for non-destructive structural 

inspections through ultra-sounds on 

poles, deep foundations, infrastructural 

works or buildings. The system 

consists of a computerised central 

unit of extremely compact sizes, 

to which it is possible to connect, according 

to the type of survey, transducers 

for surveys in direct contact or 

motorised reels controlled electronically, 

on which probes are assembled 

with drilling power, for cross-holes 

surveys. The central unit integrates 

the ultra-sound generator, 2 acquisition 

channels, the control electronics 

for the automatic management of 

the probes when being raised/lowered 

in the probing tubes in the cross-hole 

test and for saving the data on internal 

or external memory of USB type. 

Thanks to the user-friendly management 

software, all the functions are 

selected through menus that can be 

browsed simply, by touching the large 

transflective 6.4” touch screen LCD 

monitor. In CROSS-HOLE surveys on 

concrete poles, in order to obtain the 

proper measurement of the crossing 

delay of the wave and for the optimal 

receipt of the signal, the probes must 

be perfectly aligned when taking the 

measurement. Thanks to the management 

through micro-processor, 

A3000U is able to ensure the constant 

alignment between probes when taking 

the measurement, and in case the 

alignment is not achieved, it compensates 

the speed between the same 

probes. The device carries out an ongoing 

testing cycle of the alignment 

of the probes when being lowered and 

raised inside the holes. This procedure 

allows to obtain the maximum resolution 

during the acquisition phase. 

The data acquired at each single pulse 

is displayed in real time on the large 

colour monitor, allowing an immediate 

visualization of possible imperfections 

in the structure inspected. 

The procedure to carry out cross-hole 

surveys with 2 channels is managed 

by A3000U central unit in automatic 

mode. The only operations required 

to the operator consist in positioning 

the encoders for reading the position 

of the motorised probes on the tubes 

envisaged for probing and to initially 

align the probes on the pole head. At 

this point, the data acquisition is enabled 

by pressing a button, it is managed 

in automatic mode by the central 

unit, and the data can be checked 

as soon as it is acquired. Once the test 

is concluded, it is possible to print immediately 

the test report containing 

the data of the probing directly in the 

construction site. Using the contact 

transducers (supplied), it is possible 

to use the equipment in transparency 

tests of walls, trusses, partition walls 

or other infrastructural works that require 

direct surveys or as laboratory 

analyser to check specimen, concrete 

samples, rock, stony or plastic materials. 

With the direct analysis method, it 

is possible to fully analyze each wave 

generated. The instrument can be integrated 

with: 

- expansion Kit for sonic test on walls 

with electro-mechanical hammer 

- expansion Kit for I.T. TEST (eco-ranging 

test) on foundation poles 

- expansion Kit for sonic logging on

A6000U device represents the most 

complete and advanced solution for 

non-destructive structural surveys 

through ultra-sounds on deep foundations, 

infrastructural works or buildings. 

The system consists of a computerised 

central unit of compact sizes, 

to which it is possible to connect, according

the reading of the crossing speed 

and possible presence of defects in 

the material inspected. With the use 

of 3 probes with simultaneous automatic 

operation, A6000U device allows 

to save 1/3 of the time needed 

for probing, since three relative sections 

can be obtained with one single 

rising/lowering operation of the 

probes in the pole to test (which must 

be tested with 3 tubes). The system 

carries out an ongoing testing cycle 

of the alignment of the probes when 

being lowered and raised inside the 

holes. The data acquired at each single 

pulse is displayed in real time on 

the large monitor, allowing an immediate 

visualization of possible imperfections 

in the structure inspected. The 

procedure to carry out cross-hole surveys 

with 2 or 3 channels is managed 

by A6000/U central unit in automatic 

mode. The only operations required 

to the operator consist in positioning 

the encoders for reading the position 

of the motorised probes on the tubes 

envisaged for probing and to initially

Once this operation has been completed, 

the data is acquired by pressing 

a button and managed in automatic 

mode by the central unit. It is 

possible to check the data when acquired, 

so as to assess the trend of the 

test in real time. It is possible to print 

immediately the test reports containing 

the data of the probing just carried 

out in the construction site.

The ultrasound survey on contact is a standardized system in the concrete 

structure diagnostics sector, making use of a transmitter probe 

and a receiver: through an analysis of the compression (P) waves in the 

material, the transit time (T.O.F. time of flight) is obtained for the ultrasound 

waves in the material, the distance is noted and the transmission 

speed is displayed. This method, at high frequencies, is therefore 

specifically used for compact materials such as hardened concrete or 

small-size structural elements like beams, pillars, etc. 

WIN SONIC reporting software allows the display and in-depth analysis 

of individual wave forms acquired, with the aim of creating a customized 

report of the measurements carried out. 

A comparison of several wave forms can also be carried out simultaneously. 

The software is suitable for reporting data of surveys carried out with 

ultrasounds in contact or sonic tests on masonry.

SEISMIC 

EXPLORATIONS

SEISMIC 

EXPLORATIONS 

› SEISMIC EXPLORATION OF REFRACTION TYPE 

The seismic exploration of refraction 

type is among the most diffused and 

used active seismic methods. This 

type of survey has the purpose to determine 

the thickness of the overburdens 

(aerated) above a rigid sub-layer 

and reconstruct a seismic stratigraphic 

sequence in terms of apparent longitudinal 

speed. If carried out according 

to more sophisticated calculation 

methods, it can be used to intercept, 

measure and characterize geo-structural 

profiles. Seismic exploration of 

refraction type is carried out by placing 

equidistant geophones in line on 

the ground, and generating seismic 

pulses through mechanical “inputs”. 

Then the travelling times of the pulses 

that once penetrated in the ground 

are refracted nearby the lithological 

passages at different density, will be 

measured. 

› SEISMIC EXPLORATION OF REFLECTION TYPE 

The seismic exploration of reflection 

type, which is extensively used in oil 

explorations, is also used nowadays 

to obtain detailed information on surface 

soils. Due to the high resolution 

of the survey, it is used to define the 

development of geological structures 

in the sub-soil, defining the shapes, 

sizes and positions. The prospecting 

is carried out by placing high frequency 

geophones in line and close to each 

other, sending seismic pulses through 

energy (also at high frequency) and 

by measuring the travelling times of 

the waves that, once penetrated in 

the ground, are reflected by the uneven 

surfaces that delimit the lithological 

passages with net impedance 

contrast.

› Mae 25 

› TOMOGRAPHIC SEISMIC EXPLORATION 

This survey method is used to identify 

physical-geometrical anomalies of the 

sub-soil with a definitely higher resolution 

compared to the other seismic 

exploring methods, giving the opportunity 

to create an image of the subsoil 

containing all the anomalies, even 

the most complex ones, which cannot 

be resolved with other methods. 

In particular, the tomographic method 

allows to reconstruct the geometric 

distribution of the elements that 

constitute a specific section, starting 

from the analysis of the behaviour of 

the radiations that cross it. 

› DOWN-HOLE SEISMIC EXPLORING 

This type of survey is performed for 

the mechanical characterisations of 

grounds crossed during the probing 

phase. The technique consists 

in the measurement of the travelling 

times of the elastic waves between 

the seismic source on the 

surface and the geophones located 

inside the probing hole, properly conditioned 

with PVC pipe or geo-technical 

pipe. The seismic exploring activity 

in the down-hole takes place by 

placing one or more triplets of sensors 

(horizontal and vertical) inside 

one of the probing holes and at various 

depths, aimed at receiving the 

seismic signals generated through 

ram on anchored plate. Energy will 

be supplied in phase inversion in order 

to polarise phases S on a horizontal 

plane H, according to an orientation 

of 180°. Through seismic speeds 

Vp and Vs, it is possible to obtain information, 

such as elastic modules 

and geo-seismic parameters. Vs 30 

can be measured on probing holes 

up to 30 metres of depth (O.P.C.M 

3274/2003). 

› CROSS-HOLE SEISMIC EXPLORING 

This type of survey is performed 

through the physical –dynamic characterisation 

of the portion of ground 

between the two probing holes. The 

technique consists in the measurement 

of the travelling times of the elastic 

waves between the source located 

in a hole and the geophone/s located 

in another hole/s at the same depth. 

The cross-hole is made by introducing 

the borehole in one of the holes 

and the tridimensional geophone (or 

geophones) in another hole/s aimed at 

receiving the seismic signal incoming 

from the source at the same level. The 

elastic modules and mitigations of the 

medium between the holes can be obtained 

from this test.

› Seismic Explorations

› M.A.S.W. (Multichannel Analysis of Surface Waves) 

The MASW (Multichannel Analysis of 

Surface Waves) technique has the objective 

to identify variation profiles 

with the depth of the speeds of volume 

waves (Vp and Vs). The method 

is based on the known relations between 

these speeds and the dispersion 

of surface (or Rayleigh) waves 

observed when propagating through 

a stratified elastic medium. The analysis 

can be based on signals produced 

with a borehole on site by acquisition 

device (with a ram or explosion), or on 

the recording of the vibrations produced 

by far away sources (rives, industrial 

activities, traffic, etc). 

In the first case, we are talking about 

active MASW, with which it is possible 

to explore a few tens of metres of 

sub-soil, and in the second case, we 

are talking about passive MASW, that 

allows to reach greater depths, in particular 

conditions. 

Passive MA.S.W. is used with the purpose 

to obtain a speed profile 1D of 

the elastic waves of cut S. The technique 

consists in the recording of the 

“seismic noise” in temporal windows 

and following study of the signal 

processed. It is carried out by arranging 

a bidimensional geophonic chain 

with low resonant frequency in line 

or in “array” (circular and irregular geometries) 

and measuring the environmental 

noise. From the F-K analysis 

(frequency-space) of the wave-trains, 

it is possible to obtain a dispersion 

curve of surface waves that leads 

to the calculation of the speed profile 

of the shear waves and estimate 

of a coverage in relation to the semispace. 

› S.A.S.W. (Spectral Analysis of Surface Waves) 

The Spectral analysis of Surface Waves 

SASW allows to determine the speed 

profile of the shear waves of a particular 

ground. The method is based on 

the use of the dispersive properties 

of surface waves (Rayleigh) generated 

by a surface impulsive input. The 

depths explored vary from a few centimetres 

(road floors) to a few tens of 

metres. SASW is carried out by placing 

2 geophones in line, in the ground, 

with oscillation frequency from 14 

to 1 Hz, and registering the seismograms. 

The speeds profile of waves Vs 

is obtained from studying the phase 

speeds of Rayleigh waves. The data 

elaboration consists in determining 

the Coherence function, the Cross 

Power Spectrum phase and the construction 

of the dispersion curves 

of the Speed during the experimental 

phase in depth. In conclusion, the 

propagation phenomenon of the surface 

waves is simulated with the purpose 

to identify the rigidity profile 

reproduced by the experimental dispersion 

curve.

› PASSIVE SEISMIC – EXPLORATION FOR THE EVALUATION OF THE 

LOCAL SEISMIC RESPONSE – MICRO EARTHQUAKES 

This technique is used to obtain information 

concerning possible dynamic from the convolution of the frequen- 

the study of the spectrums obtained 

amplification effects of seismic waves cy of the signal recorded in the domain 

for the three components of the 

in “ emersion ”. It is based on the recording 

of the background noise in ground motion and the application 

the time domain and following elaboration 

of the signal’s frequencies in (H/V), allows to define and measure 

of techniques on spectrum analysis 

the domain. It is carried out by placing 

a tridimensional geophone on the and the seismic frequency of the 

possible local seismic amplifications 

ground with low frequency response site. The measurements of the microearthquake 

can also be taken in linear 

and by recording the seismic noise in 

different temporal windows. Later on, “arrays” for the localization of faults. 

› NAKAMURA METHOD 

A significant part of the damages observed 

in destructive earthquakes all 

over the world is associated with the 

amplification of seismic waves due to 

the effects of the local site. The analysis 

of the site response is therefore essential 

in the evaluation of the seismic 

risk in areas subject to earthquakes. 

In order to evaluate the effects of the 

local site, a series of surveys must be 

carried out. Among the empiric methods, 

the method of spectrum analyses 

H/V on environmental vibrations is 

one of the most common. The method, 

also called “Nakamura” technique 

(Nakamura, 1989), was introduced by 

Nogoshi and Igarashi (1971) based on 

the initial studies of Kanai and Tanaka 

(1961). Since then, many researchers 

worldwide performed a large number 

of applications. 

An important requirement to carry out 

the H/ V method consists in a fairly good 

knowledge of seismology combined 

with basic information on local geological 

conditions supported by geo-physical 

and geo-technical data. The method 

is generally applied in micro-zoning 

studies and in the analysis of the local 

response of specific sites. 

› SEISMIC MONITORING 

Seismic monitoring is carried out in areas 

subject to risks related to a seismogenic 

activity, by acquiring the 

seisms with time and recording the 

seismograms. Seismic stations are 

used able to record in threshold or 

continuous type, and low frequency 

geophones or seismic accelerometers. 

The recording in the long period, 

of the earthquakes relative to a 

site or fairly large area allows to configure 

the seismic scenario of an area 

and evaluate the risk and vulnerability 

conditions. If the monitoring activity 

is supported by specific knowledge 

of geological and geo-technical 

type, we are talking about seismic Micro-zoning.

MAE A6000S 24-bit seismograph for 

seismic prospecting stands out for its 

data acquisition platform of last generation 

combined to the user-friendly 

operative system structured in menus 

that can be browsed, with different 

functions according to the type 

of seismic probing selected by simply 

touching the colour, touch-screen 

monitor of large sizes. 

The main characteristic of this series 

of seismographs is the 24-bit 

resolution for each single channel. 

This result is achieved thanks to the 

adoption of a new, 24 bit, MAE data 

acquisition card that uses an A/D digital 

converter for each inlet channel 

of the seismograph (SST technology). 

The adoption of this architecture 

renders A6000S ideal for all types of 

active and passive seismic prospecting, 

and for structural surveys and inspections 

on buildings and infrastructural 

works (acquisition of vibrations 

with accelerometers or low frequency 

seismic sensors, tomographic surveys, 

etc). 

Thanks to the great versatility and 

numerous automatic, pre-acquisition 

checking procedures, from the proper 

connection of the geophones to the 

analysis of the noise relative to the 

site inspected, the data acquisition 

is always particularly easy to handle 

by anybody. It is also possible to carry 

out a first analysis of the data acquired, 

also for single wave, directly 

on site, visualizing the seismograms 

in details, with just a few simple operations. 

The data is saved on an internal, 

solid state hard disk, for better 

protection in case of collisions, or 

on an external USB memory.

SETA SYSTEM 


Seismological studies 

Territorial seismic monitoring 


The seismic acquisition system called SETA 

SYSTEM has been developed by MAE in jointventure 

with partners of high profile, such 

as: the National Institute of Oceanography 

and Experimental Geo-physics, OGS, located 

in Trieste, and the National Institute of Geophysics 

Georgiano, IGEM, located in Tbilisi. 

The system allows to create architectures 

for seismic networks in digital telemetry 

with 24-bit resolution, using the two basic 

units of the system or the RX-16 receiver, 

with 16 inlets for as many transmitting 

units TX-3, properly located on the territory 

that must be monitored. The S.E.T.A system 

has been developed with the purpose 

to create a vast territorial network of seismic 

monitoring stations, completely independent 

in terms of energy and radio communications, 

able to monitor the seismic/ 

micro-seismic activity of the territorial area 

where it is located, 24 hours a day. The remote 

units are installed in suitable rural containers, 

which characteristics are developed 

based on the specifications of each system. 

These are usually fed by battery packs with 

high autonomy, re-charged through solar 

panels or other solutions. The digital transmitting 

unit TX- 3 AD is equipped with 3 inlet 

channels with 24-bit resolution, and allows 

to use velocimeters with 1/2 Hz frequencies 

or mono and three-axial accelerometers, in 

addition to geophones of different frequency. 

It is stored inside a sturdy steel container, 

it codes and transmits via radio the signals 

coming from the seismic sensors to 

the Data Collection Station, with which it is 

in constant connection, where one or more 

RX-16 units have been installed, which receive 

and decode the data acquired locally 

by the remote units. The data transmitted 

by the RX-16 in real time can be then treated 

with different types of analysis software 

and stored through proper procedures, thus 

allowing the creation of an archive of seismic 

events of the geographic region object of the 

study. The data collected allows to know and 

constantly monitor the seismic activity in 

the monitored region. The system has been 

conceived to work with automatic recording 

and signalling modes of the events that occur 

on all the remote stations connected to 

the system. The data coming from the remote 

stations of the network can be viewed 

on the terminals of the Data Collection Centre 

24 hours a day.

› ESP - SEISMIC GAS EXPLODER WITH COMBUSTION CHAMBER 

The ESP2 Seismic Energizer is a source of seismic energy used to “energize” the soil to 

better determine the nature of the soil itself, as well as its stratigraphy, through a seismic 

prospection. The system operates by means of two steel cylinders that, once the detonation 

is triggered, move one inside the other thereby energizing the underlying soil. This gas 

exploder apparatus is extremely simple and safe for the operator to use since the trigger is 

operated by remote control. The detonation is ignited thanks to the built-in rechargeable 

12V battery. A bayonet clutch allows the cartridge to be replaced quickly and easily.

SOFTWARE 

mae-srl.it/go/pslab 

› PS-LAB 

PSLAB allows simple processing of seismic data in SEG2 format relating 

to surveys for refraction or with down-hole technique. Through a 

guided path, the program enables a detailed report of the survey to 

be obtained, accompanied by graphics and tables, starting from the 

field data. For surface seismic analysis, identification of the depth of 

refractors is based on the generalized reciprocal method (GRM), which 

requires a minimum of three energizations along the extent and calculates 

the depth below each geophone and the average speeds of 

compression waves in the seismic layers. When identification of the first 

arrival times has been performed, directly on seismograms with different 

graphic aids or with manual entry in a table, the analysis of travel 

time graphs is made simple by an intuitive approach that provides for 

the times observed to be attributed to the different refractors by means 

of a simple mouse-click. For the down-hole technique, there is automatic, 

fast loading of all measurement files in a particular folder. Calculation 

of Vp and Vs speeds is based on the interval method. The program 

calculates the speeds and the corresponding Poisson module for 

each layer detected by analysis of the travel time graphs and the Vs30 

average for the entire log.

GEO-ELECTRIC 

EXPLORATIONS 

› S.E.V. (Vertical electric explorations) 

This type of survey is carried out 

with the purpose to reconstruct an 

electro-tomography 1D for a measurement 

point. The geo-electric 

method consists in the experimental 

determination of the resistivity distribution 

characterising the electric 

structure of a medium. In the SEV 

method, the distance between the 

electrodes is increased progressively 

and the ratio between d.d.p. and 

the current intensity is measured 

from time to time. The resistivity 

values thus obtained are influenced 

by the characteristics of the materials 

at increasingly greater depths. 

In view of this second effect, a geometric 

correction must be made and 

therefore factors that depend on 

distances MN (measurement electrodes) 

and AB (input electrodes) 

must be introduced in the calculation 

of the resistivity. According to 

the variations of the electrodes positions 

along the geo-electric area, 

different quadrupole systems are 

identified: Wenner and Schlumberger. 

A profile 1D of the ground resistivity 

is obtained below one point.

› Mae 47 

› S.E.O. (Horizontal electric explorations) 

This type of survey is carried out with 

the purpose to obtain a resistivity profile 

of the ground along a direction and 

at a certain depth. Each unhomogeneity 

in the medium tested, like bodies with 

different electric conduction capacity, 

is identified because it deflects the current 

lines and distorts the regular distribution 

of the electric potential. Furthermore, 

by measuring the potential 

drop on two random points, it is possible 

to determine the electric resistivity 

of the medium by multiplying the ratio 

between the potential drop and the 

current sent by a geometric coefficient 

which depends on the position of the 

electrodes on the ground. By changing 

the position of the electrode device on 

the area to test, it is possible to determine 

the distribution of the resistivity 

in the volume subject to electric current. 

Since rocks are resistive materials 

by nature, the resistivity variations are 

due almost exclusively to the presence 

of water in different quantities. The SEO 

is carried out by fixing 4 electrodes in 

the ground, two of which (the external 

ones) are for anchoring purposes 

and the other 2 (internal ones) are for 

measuring purposes, at a certain distance 

from each other. It is possible to 

obtain a horizontal profile of the resistivities 

of the grounds, which is useful 

to identify a vertical passage between 

two bodies with different resistivity. 

› RESISTIVITY TOMOGRAPHIC GEO-ELECTRIC PROFILE 

(Electric tomography) 

This type of survey is based on the 

calculation of the resistivity from the 

d.d.p measurements in the ground. The 

method is based on the introduction of 

an electric field in the ground through 

electrodes (input or current) and the 

measurement of the d.d.p. in other 

electrodes (of measurement type). 

From the d.d.p. value, it will be possible 

to find the resistivity value through the 

second law of Ohm, which is a typical 

characteristics of all materials. Since 

rocks are resistive materials by nature, 

the resistivity variations are due almost 

exclusively to the presence of water in 

different quantities. Electric tomography 

2D-3D is carried out by fixing electrode 

grids in the ground (16, 32, 64, 

128….) at constant pitch. All of them 

are connected to boxes which allow 

commutation among them, defining 

which are the measuring and current 

electrodes from time to time and automatically. 

The system will automatically 

perform all possible combinations. 

For this purpose, a series of measurements 

will be obtained (as many as the 

combinations available), based on: the 

number of electrodes and type of geometric 

configuration used. The tomographic 

inversion of the data obtained 

on the surface generates a bidimensional 

or tridimensional reconstruction 

in “output” of the ground, from which it 

is possible to identify possible anomalies 

due to cavities, water bodies, etc, 

and identify shapes, sizes and spatial 

distribution.

› Geo-Electric Explorations 

48 

› INDUCED POLARISATION 

The Induced Polarisation (PI) is an 

electric phenomenon that occurs inside 

of material media in the time domain, 

with the release of stresses upon 

the interruption of a flow of electric 

current of step type (in this case, it is 

measured as chargeability) and also in 

the frequency domain, with a precise 

dispersion law of the electric resistivity 

upon the variation of the frequency 

of an alternated current flow. A PI 

source is connected to the oxido-reductive 

processes along the interface 

between the metal grains and interstitial 

fluids (electrode polarisation). Another 

important PI source consists instead 

of ionic accumulations in moving 

electrolytes due to mobility variations 

along the path (electro-kinetic polarisation). 

The tomographic inversion of 

the data obtained on the surface returns 

the ground in “output” based on 

chargeability images, thanks to which 

it is possible to identify possible accumulation 

areas or significant concentrations 

of hydrocarbons. The chargeability 

is proportional to the charge 

stored by the lithotype and it represents 

the concentration of a conductor 

in the multi-electrode area. 

› SPONTANEOUS-POTENTIAL METHOD 

The Spontaneous Potential method 

(PS) consists in determining on 

the surface, the differences of potential 

related to a natural electric 

field, linked to the underground circulation 

of aqueous electrolytic solutions 

in porous media. From the analysis 

of PS anomalies in the surface, it 

is possible to determine the intensity 

and position of the concentrations 

of ionic charges with both polarities. 

The test is carried out by positioning 

two electrodes: the first one close to 

the measurement station and the other 

one is moved on the following stations 

of the line; of both electrodes 

are moved, by keeping stable the interval 

between them, mapping the 

ground based on the spontaneous potential. 

The use of this method is useful 

in the mining field for the search 

of sulphides and graphite, but also in 

the archaeological field, indeed water 

circulations can be affected by underground 

archaeological structures, 

that could act as drain or as obstacle, 

and therefore, with the identification 

of PS anomalies, it is possible in general 

to find underground archaeological 

structures indirectly.

MAE A6000SE combined instrumentation 

represents the most compact and 

versatile solution for active and passive 

seismic prospecting (24 channels, 

24 bit) and geo-electric prospecting, 

with quadripole (SEV) techniques or 

multi-electrode electric tomography. 

The type of seismic or geo-electric 

probing to carry out is selected from 

the main menu, by simply touching the 

colour, touch screen monitor. Once the 

data acquisition method has been set 

(single measurement or cycle), the 

data is automatically acquired by the 

device by simply pressing a button. 

The main characteristic of the seismograph 

section is the 24-bit resolution 

for each single channel. This 

result is achieved thanks to the adoption 

of a new, 24 bit, MAE data acquisition 

card that uses an A/D digital converter 

for each inlet channel of the 

seismograph (SST technology). The 

adoption of this architecture renders 

A6000SE ideal for all types of active 

and passive seismic prospecting, and 

for structural surveys and inspections 

on buildings and infrastructural works 

(acquisition of vibrations with accelerometers 

or low frequency seismic sensors, 

tomographic surveys). It is also 

possible to carry out a first analysis 

of the seismograms acquired, also for 

single wave, directly on site, visualizing 

the seismograms in details, with 

just a few simple operations. 

The georesistivity meter section of 

A6000SE is characterised by utmost 

resolution and accuracy in the geoelectric 

survey and extreme operative 

promptness thanks to the use of highly 

resistant cables for geo-electric prospecting, 

equipped with 16 plugs each, 

with intervals of 2; 3; 5 or 10 metres 

each. The instrument takes the measurement 

or carries out the measurement 

cycle set by the user in automatic 

mode; once the measurement cycle 

is completed, the acquired data can be 

immediately processed with the relative 

elaboration software.

MONITORING 

› NON-DESTRUCTIVE TESTS 

The Non Destructive Tests (NDT) consists 

in a series of assessments, tests 

and surveys carried out with methods 

that do not alter the material and do 

not require the destruction or removal 

of samples from the structure tested, 

aimed at finding and identifying structural 

defects of the same structure. The 

acronym NDT derived from the English 

expression Non Destructive Testing, is 

often used or acronym P.n.D., derived 

from Non Destructive tests (in Italian). 

In the industrial sector, each product 

of critical importance (beams for construction, 

support screws, aeronautical 

components, car components, pressure 

bodies) must be checked to assess 

its integrity and conformity with 

applicable laws. The primary objective 

of non destructive tests is therefore to 

foresee the cracking of materials and 

objects, thus covering an essential role 

to prevent economic damages due to 

possible accidents and also to guarantee 

a high level of safety for operators. 

Reinforced concrete structures 

(masonry), particularly important for 

their long-life and unlimited endurableness 

to continuous and uncontrollable 

changes, excluding disastrous 

events (earthquakes, thermal shocks, 

landslides, etc), ) in the majority of 

the cases showed phenomena of progressive 

deterioration during their life. 

These defects are linked to the executive 

phase of the works, aggressiveness 

of building materials (alkalis – silica 

reactions), micro-holes produced 

by water-thermal variations, sagging 

of foundations or grounds, static-dynamic 

operating stresses. The non invasive 

character of this method applicable 

to existing works allows to verify 

the physical and mechanical characteristics 

of the materials that constitute 

the structure. 

› MEASUREMENT OF HEAT TRANSMISSION ON SITE 

In building technology, the testing of 

the insulation capacity of building materials 

is an important topic of study. In 

addition to laboratory measurements 

of the thermal properties of materials, 

their behaviours is also studied through 

tests on field, in order to obtain information 

on the behaviours in different 

climates. The total heat flow through a 

material consists of a conductive, convective 

and radioactive part. In order to 

measure the heat transmission, a heat 

flow meter and some thermometers 

are used, assembled on both sides (interior 

and exterior) of a wall. After recording 

the flow and temperatures for 

a few hours, measured with high precision, 

the data is elaborated to obtain 

the average heat transmission of 

the wall.

› Mae 59 

› LOAD TESTS 

The load tests have the primary objective 

to compare the experimental 

arrows obtained during the testing 

phase and the theoretical arrows 

of the project, in order to evaluate 

the deformation profile of the element 

tested. The test loads used can 

be distributed (bricks, blocks or cement 

bags, water tanks) or similar 

concentrates (hydraulic jacks). The 

tests that use similar concentrated 

loads can be of pull or push test type. 

The result of the load tests and elastic 

behaviour of the structure is represented 

through load/shift graphs and 

hysteresis curves. The measurement 

of the shifts and deformations can be 

taken with manual systems, such as 

mechanical comparators or deflectometers 

or with automatic-electric 

systems, such as movement transducers 

(resistive, inductive, potenziometric). 

The use of these electric systems 

allows continuous, stable and 

precise readings that can be transmitted 

also far away from the relative 

testing area. Rapidity of execution, accuracy 

and safety make this system 

the most diffused one nowadays, in 

the test and trial sector. 

› MEASUREMENT OF THE HEAT TRANSMISSION IN GROUNDS 

The measurement method is based 

on the so called unstable sensor technique, 

that uses a probe (also called 

thermal needle), which mounts a heating 

wire and a temperature sensor. The 

probe is introduced in the ground. From 

its response when subject to a heating 

cycle for a few minutes, it is possible 

to calculate the thermal resistivity (or 

its opposite, the heat transmission). 

The principle of the measurement is 

based on a peculiar characteristic of 

a rectilinear heat course (the heating 

wire of the probe): after a short transitional 

period, the increase of the temperature 

depends only on the heating 

power and heat transmission of the 

medium. Once the first is known, the 

second can be calculated. The main 

applications of the technique consists 

in the testing of high voltage cables 

and heating ducts.

A5000T 


Measure of soil thermal conductivity 

A5000T is a device specifically studied 

to measure the heat transmission of 

the ground (tendency of the ground to 

transmit heat). This type of survey is 

usually carried out prior to install the 

underground cable ducts, or prior to 

build the geo-thermic wells to detect 

the heat from the ground, for heating 

or conditioning buildings. The measurement 

can be taken on site with 

the probe supplied, up to a depth of 

120 cm, or in case of greater depths, 

it is possible to pick up samples of 

compact ground (logs) and take the 

measurement in the laboratory with 

the relative laboratory probe. The acquired 

data can be examined directly 

on site, at the end of the acquisition 

phase regulated automatically by 

the device and it is expressed graphically 

and numerically in watt / (metres 

x kelvin) where: watt = unit of power; 

metre = unit of distance; kelvin = unit 

of temperature. In operative terms, 

a hole is made in the ground using a 

common drill (not supplied) and a perforation 

point of 20 mm diameter with 

prolonged rod (supplied). Then, the 

probe is introduced in the hole and 

by pressing slightly, the point of the 

probe is fixed into the ground by about 

20 cm, with the purpose to obtain the 

best coupling with the ground. The 

data acquisition procedure is initiated 

by pressing a button, it is managed 

automatically by the instrument, and 

lasts a few seconds. The numeric and 

graphic data is stored on SD memory 

and then elaborated with the relative 

GT-LAB software supplied with the instrument.

SOFTWARE 

› GM-LAB 

Software for managing measurements produced by instruments for 

monitoring. It facilitates data analysis thanks to the possibility of displaying 

graphics from different sensors. Through a simple and intuitive 

user interface, it is possible to manage the numerous functions of the 

application that allow storage of data from the monitoring concerned 

and the making up of test reports, professionally and quickly. 

Main functions: 

- Printable report of the data read and relative graphics, photos and indication 

of place of monitoring 

- General information on the site or structure being monitored 

- Type, number of sensors used and their location on the structure 

- Value of movements detected during the monitoring phase 

- Progressive systematic description of cracks through graphic displays 

of time diagrams 

- Automatic calculation of x and y movement for double measurement 

points 

The most useful feature of the GM LAB software is its multi-parametricity 

- that is, the possibility of managing data from many types of sensors 

in order to allow maximum freedom in configuring the sensor systems 

necessary for monitoring requirements.

› GT-LAB 

Software for calculating CONDUCTANCE and TRANSMITTANCE. 

The GT Lab program enables conductance and transmittance calculations 

by importing data measured with a thermal flux-meter. 

CONDUCTANCE 

The conductance calculation is carried out with the progressive averages 

method. By this method, the conductance is obtained not by using 

instantaneous values for temperature and thermal flow, but by taking 

account of the values calculated on averages obtained from the total 

of the readings performed. 

TRANSMITTANCE 

The transmittance calculation is carried out by selecting the surface 

coefficients of heat exchange, which combine the effects of the above 

phenomena and are tabulated in UNI 7357/76 Regulations and subsequent 

adaptations according to the geometrical situation (e.g. vertical, 

horizontal structure, etc.), and in the UNI regulations accompanying 

Law 10/91 (e.g. in the UNI 10345 regulations for window elements).

› PC-LAB 

Software dedicated to display and storage of data acquired during load 

tests on floors or other load-bearing elements carried out with M.A.E. 

instrumentation. 

The test consists of producing, on a longitudinal line of the floor, one or 

more concentrated forces. The forces are calculated so as to produce 

the same maximum state of stress laid down in the design for applying 

the distributed load. 

When receipt of data starts, the software records the measurements on 

entry, displays them and creates the graphics in real time. 

The load value can be read automatically or entered manually. 

The reading of the data may be continuous in real time or at manual intervals 

with recording of the data decided on by the user. 

Data and Graphics displayed in real time. 

Possibility of analysing the graphic for one or more channels simultaneously. 

Report creation with tables of measurements read and graphics generated. 

Accepts LAN and USB connections.

› MULTI MONITOR 

Connection platform for data acquisition systems. The software allows the 

connection, display (also in real time) and storage of the data acquired by 

M.A.E. instrumentation installed locally or remotely, through different interface 

modes. 

Common characteristics: 

- management of filters on the display of data 

- instrumentation battery-level reading 

- management of alarm thresholds and sending alarms by email or text 

message 

- saving data received in real time with possibility of dividing archives on a 

time basis 

- downloading data stored on internal memories. 

mae-srl.it/go/multimonitor 

The platform allows for connection to the various instruments installed, 

by means of: 

LAN 

software for reading data from M.A.E. instruments connected in LAN 

reading of data from several stations in real-time. 

The application allows the management of connection by LAN to all remote 

units; it is also possible to display the status of sensors connected to the remote 

units, even simultaneously. 

GSM 

Software for connection to M.A.E. instrumentation through GSM 

scheduled monitoring on several machines. 

Range query modifiable by the user (from 2 minutes to 1 month) 

real time on individual machine. 

USB 

Software for connection to M.A.E. instrumentation by USB 

reading in real time on several machines. 

› ALARM-MANAGER 

Software for managing alarms from monitoring stations. Receives 

alarms notifications by text message sent by detection units. Shows 

on video the list of alarms received with information such as place of installation 

of the station, sensor in alarm and type of alarm found. A log 

is also generated with all the alarms that have occurred, with recording 

of date, time, station of origin and sensor in alarm. 

The software allows programming of alarm thresholds settable by the 

user for each channel; when these thresholds are reached or exceeded, 

a call or alarm text message is sent automatically to one or more numbers 

entered in the station at the time of programming.
