before use 

Easi-Flex System – Glipp Sealing System 

Widely used throughout Europe, the Glipp system is designed to improve joint 

performance, whilst making life easier for ‘the man in the trench’. 

• Reliable Joints 

• Watertight Joints 

• Simplified Jointing 

• Long, Reliable Service Life 

Easi-Flex is a system in which the seal forms an integrated part of the pipe joint. The 

position of the sealing ring is fixed in the socket, which guarantees watertight and 

secure pipe joints. 

The Easi-Flex joint is a sliding joint. This requires the application of lubricant to the 

spigot prior to assembly. Sliding joints have an advantage that, if sand, gravel or clay 

stick on the spigot, they are easily wiped off the sealing surface during assembly. The 

Cast-in protective strip ensures the seal is in the correct position during manufacture. 

The Protective Strip also ensures that the pipe socket is ‘clean’ and free from dirt, 

stones, mud etc... prior to jointing. The Protective Strip is made of a non-toxic cellular 

plastic material. Details are available upon request.

Easi-Lift Pipe Lifter 

P8 

The new ‘Easi-Lift Pipe Lifter’ has been designed as an excavator 

attachment solely for use in the lifting and laying of concrete 

pipes. All moving parts are mechanical and do not require the 

excavator to have additional hydraulics. This pipe lifter has been 

built with the safety of the user in mind. 

Safety Features 

Offloading - the banks man is not required to enter a trailer to offload. 

Installation - ground workers are not required in the trench during 

the actual pipe installation (i.e. whilst the excavator is working) 

The Easi-Lift Pipe Lifter offers a user friendly solution in pipe 

installation, and has the following unique benefits and features: 

• 30 degree tilt for guiding the pipe into position. 

• Swivel plate - allowing the AP1 Pipe Lifter to turn at 90 degree 

intervals. 

• Tested to a safe working load (S.W.L) 3700kg. 

• Saves time in installation 

• Increases safety during installation 

• Provides easy access to apply joint lubricant prior to positioning

Easi-Flex Anchor System 

P9 

FP McCann pipes from DN1350 should be handled using our purpose designed Easi-Flex Anchor System. 

Special lifting Anchors can be cast into pipes at manufacture. A Universal Head Link (Available from FP 

McCann) can then be hooked onto the exposed anchor heads to lift the pipe. 

Use the equal lengths (1 & 2) for lifting the pipe. 

Join the longer chain (3) onto the pipe already laid 

and place the shorter length (2) onto the hook. 

The pipe can then be jointed without moving the jib 

of the crane.

Handling/Lifting Instructions 

Pipe Diameters DN1800 to DN2400 are designed and 

manufactured to incorporate Easi-Lift jointing and 

lifting system. 

Easi-Lift System 

A 

The Lift 

To lift the pipes, select the two short legs A and B on 

the chain set. Place the spherical coupling over the cast 

in anchor and engage by turning the tail of the head 

link down to the concrete. The pipe can then be lifted 

as normal. 

Never pass slings or other lifting appliances through 

the barrel and never lift more than one pipe at a time. 

Jointing 

C 

B 

Ensure that the seal is of the correct size, and is not 

damaged. 

Ensure pipe sockets and spigots are not damaged. 

Position the rubber ring on the end of the spigot end. 


Easi-Lift joint 

To joint the pipe using the chain system. Attach the long 

leg C to the already laid pipe and the short leg B to the 

pipe to be laid. Take up the slack in the chains with the 

lifting pulley over the anchor of the laid pipe, and increase 

the upward force to joint the pipes. When jointed, ensure 

that there is no excessive slew or misalignment, this can 

easily be checked by reference to the joint gap. 

Joint Gap 

Notes: 

1. All dimensions are in mm. 

2. Weights in kg are based on a concrete density of 

2500kg/m³. 

3. Where relevant pipes are manufactured in 

accordance with BS EN 1916. 

4. Note right hand or left hand junctions (viewed 

socket to spigot) should be specified when 

ordering reduced junctions in pipe diameters 

DN1800 and above. 

5. Note lifting chains are not suitable for joining 

purposes in pipes of diameter DN2400. Joint in the 

traditional method. 

6. All junctions to be installed on their side only.

Handling & Laying Instructions 

P13 

Recommended Site Work Practice – Open Cut Flexible Jointed Pipes 

Handling & Storing Pipes 

1. Time and place of off-loading should be agreed before the units arrive at site. The contractor should provide suitable equipment for off-loading, stacking and 

stringing out of pipes on site. 

2. Off-loading should take place at the nearest hard road to the point of installation. To ensure the safety of all personnel, units must be left in a stable position 

well clear of the edge of the trench. 

3. Pipes should be inspected before off-loading to ensure that materials delivered correspond to order placed. 

4. Pipes should be carefully checked during off-loading to ensure no units are damaged. Any discrepancies should be 

recorded on the delivery docket. 

5. Where stacking is necessary, this should be done on level ground and the bottom layer of pipes securely chocked to 

prevent the stack from collapsing. Pipes should be supported under the barrel so that the socket is free of load so that the 

jointing faces are not damaged. They should preferably be stacked barrel to barrel with sockets hanging over alternative 

sides. 

6. For safety reasons and to prevent damage to the lower layers of pipe in the stack, pipes should not be loaded or stacked 

in a greater number of layers than is shown in the table below. 

7. Avoid damage when handling, especially to ends of concrete pipes. Never drag or roll pipes over the ground. 

Note: FP McCann Easi-Flex pipes from DN1350 can be handled using our purpose designed Anchor System. Special lifting 

Anchors can be cast into pipes at manufacture. A Universal Head Link (Available from FP McCann) can then be hooked 

onto the exposed anchor heads to lift the pipe. Lifting Anchors are fitted to order. 

Laying Pipes 

1. Trench Excavation - The trench should be excavated to the line, gradient and width indicated in the contract documents or as agreed with the engineer. The 

safety of the public and site personnel is of paramount importance and care should be taken to ensure personal safety at all times. 

2. Trench Width - Any increase in trench width above that specified could increase the load on the pipe; increasing the quantity of excavation and the bedding 

material required. A trench narrower than the specified width may impede the proper placing of bedding or backfill material or the correct jointing of pipes. 

3. Formation - Uniform support along the pipeline is essential. Rock outcrops and soft zones, which can cause differential settlement should be dug out and 

replaced with compacted specified backfill material. De-watering may be necessary during pipe laying and subsequent backfilling operations. The specified 

bedding material shall be placed as detailed in the contract specification and trimmed to ensure uniform support of the pipe throughout the length of its barrel. 

Recesses should be prepared for the pipe sockets. 

4. Pipe Laying - Before being lowered into the trench, pipes and fittings should be inspected to ensure that they have not been damaged during handling and 

storage on site. Units should be lowered carefully into the trench using recognised lifting tackle such as the Easi-Lift mechanical pipe lifter. 

5. Jointing - Using our integral Easi-Flex Sealing System all pipe spigots must be fully lubricated with the pipe lube supplied just prior to being lowered into the 

trench. Please note, pipes should only be joined using an FP McCann approved lubricant. The socket of the laid pipe should at this stage be prepared by 

removing the polystyrene forming ring to leave a clean seal free from debris. The adjoining pipe should be lowered into position as level as possible centring the 

pipe spigot with the seal of the laid pipe so that the pipes are in line. On achieving this apply pressure to the socket end of the adjoining pipe using a substantial 

piece of timber to protect the pipe from damage when pushing the pipe home. 

6. Testing - Acceptance tests on the completed pipeline give an indication of the level of control of workmanship and materials during construction. 

7. Visual Testing - Check for obstructions and debris within the pipe, the structural soundness of pipes, that joints are properly sealed and that the pipe invert is 

even. Note: pipes smaller than DN750 may be inspected from manholes or by means of TV cameras. 

8. Water Tightness - The water tightness of a pipeline may be checked using a water or air test. Such tests will reveal the existence of cracked or porous pipes 

or faulty joints. These tests should be made during and after laying and before backfilling. The test method will be detailed in the contract specification or 

referenced to an appropriate code of practice. In certain circumstances (e.g. where the distance between manholes is great, or when site conditions are such 

that backfilling must take place immediately or when laying small diameter pipelines), it is recommended that the pipeline be tested at regular intervals (say 

every 3 pipes) during construction. 

9. Backfilling - After inspection and testing backfilling should proceed. The attention given to backfill selection is of great importance. The placing and compaction 

of inappropriate backfill may cause damage to a new pipeline. The structural strength of the completed pipeline depends as much on good site workmanship 

as on the strength of individual pipes. Consequently all backfill material must be selected and placed as detailed in the contract specification or recognised code 

of practice. 

Note: For additional information on laying pipes see the CPSA website.

bituminous sealant. An F P McCann approved sealant should be used at all times. The sealant requirement for wide wall 

manholes is 12mm x 120mm x 6m. When placing sealing strip into position during installation, the ends of the strips must 

be overlapped by a minimum of 30mm and cut at an angle of 60 degree. The cut ends must then be pressed together. Full

Recommended Site work 

Practice – Manhole Chambers 

P20 

Handling & Installing Manholes 

1. Time and place of off-loading should be agreed before the units arrive at site. The contractor should provide suitable 

equipment for off-loading. For safety, all chamber sections are delivered chimney fashion. 

2. Off-loading should take place at the nearest hard road to the point of installation. When off-loaded, units should never 

be stored on their side (on the roll), but should always be laid in the “as installed” position. 

3. Carefully inspect units during off-loading to verify that products are undamaged and comply with order placed. Note 

any discrepancies on the delivery docket. 

Recommended Lifting Equipment 

Construction 

To ensure that the manhole structure is vertical, accurate levelling 

of the formation or the in-situ concrete foundation is essential. 

Tongue and groove joints should be installed with the socket 

facing upward. Manhole sections fitted with double steps can be 

used in any depth configuration. However, it is recommended that 

the deepest section of manhole units should be used whenever 

possible in order to minimise the number of joints and costs. 

Precast cover slabs can be laid directly onto the shaft or chamber 

rings. 

To allow for any differential settlement between manhole and 

pipeline, a flexible joint incorporating short length rocker pipes 

should be constructed as close as possible to the outside of the 

manhole or the concrete surround if used. Extra care must be taken 

to ensure that joints are properly made.

Jointing 

Precast manhole components are provided with joints formed 

within the wall section. These are sealed with cement / sand mortar 

or with proprietary mastic sealants. Precast concrete manhole units, 

well jointed, provide an adequate seal under normal conditions.

structure with its own inherent strength and would only require a surround for exceptional structural reasons. However 

under some specifications a concrete surround is required where the depth from ground level to the base of the concrete 

chamber rings, exceeds 4.5m. Such surround should be of 150mm thickness. Backfilling should take place as each precast 

manhole section is placed. It must be brought up evenly and compacted around the manhole to prevent displacement. 

Testing 

It is generally unnecessary to apply water tests to manholes. In working conditions manholes are not normally full of water. 

Prevention of infiltration is of more relevance than ex-filtration. If infiltration does occur it can be seen and remedied by 

sealing using an appropriate method. 

Note: When handling precast products on site it is recommended that the contractor has the correct lifting equipment in place and 

adheres to the relevant lifting guidelines and standards. Refer to:- www.concretepipes.co.uk/technicalguides/index.php

Easi-Safe Fall Arrest System 

P23 

Award Winning Safety Solution For Manhole Construction 

The client, consultant engineer, contractors and suppliers all have a duty to mitigate hazards on site whenever 

reasonably practicable. 

One such hazard identified is the risk of operatives falling through manhole openings particularly during the 

construction process and also in follow up maintenance work. 

Working with partners Severn Trent Water, engineer Grontmij and contractor to the water sector, Morgan 

Sindall plc, FP McCann have designed a safety award winning solution. Easi-Safe is a temporary or permanent 

fall arrest system that allows for safe working around the manhole opening prior to the fitting of the ironwork. 

In the construction of a manhole, operatives often work unprotected from the opening at surface level when 

the final stages of completion occur. This includes the final brickwork up to the manhole frame and the mortar 

bedding of the frame itself. 

UNPROTECTED 

With most standard cover slabs, the access point for man entry is open and it is left to the contractor to cover 

on site. In many site situations these openings remain for a number of days while gangs complete phases of 

work. Easi-Safe immediately addresses this problem. The future production of all standard access cover slabs 

will incorporate the optional protective grid which will remain in the slab even when the final D400 steel 

cover and frame are set in place at surface level. 

The galvanised mild steel grid is available in four standard sizes:- 

• 610mm x 610mm 

• 675mm x 675mm 

• 750mm x 600mm 

• 1200mm x 675mm 

The Easi-Safe grid is seated on load bearing corners precast into a standard range of manhole cover slabs. As 

a temporary fall arrest system, once the construction of the manhole is complete, the grid can be removed 

prior to the fitting of the ironwork. Alternatively, Easi-Safe can be a permanent fixture, left in place beneath 

the manhole lid. The spacing between the bars allows for ease of inspection and jetting of the manhole base 

during maintenance work.

Features 

• The DN1200 Easi-Base is made to an internal diameter of 1200mm with tongue and groove joint 

profile to match standard DN1200 manhole chamber rings. 

• Wall thickness is 150mm. 

• The base has a 150mm floor thickness with the outlet invert at exactly 150mm from ground level. 

• A 1% fall exists across the channel toward the outlet (1:100). 

• A gradient of 1:10 is present at the benching with the run-off toward the channel. 

• The height of the DN1200 Easi-Base unit varies in accordance with the diameter of the main 

channel running through the unit. (Please refer to the table above for approximate heights). 

• The DN1200 Easi-Base unit has 5° flexibility in the seal at each pipe connection point, this can be 

achieved both horizontally and vertically. (This is best illustrated in the diagram below). 

• Additional connections can be made to a DN1200 Easi-Base unit once installed. This can be 

achieved either by coring into the existing unit and fitting a connection in the traditional manner; 

alternatively by the use of a backdrop into the manhole. 

• Easi-Base is a Kitemark product - manufactured and tested to BSEN 1917. 

• Easi-Base meets with WRc Approval. 

• Easi- Base is accepted for use by all major UK water companies. 

Note: A copy of the WRc Approval and copies of water company acceptance letters are available

DN 1500 & DN 1800 Precast Concrete Easi-Base 

DN1500 - DN1800 

Easi-Base (GRP & Unlined) 

P28 

The Easi-Base range extends to include the larger diameter DN 1500 and DN 1800 concrete manhole bases. These 

bases will accommodate concrete, clay, twin wall and uPVC pipes from DN 300 to DN 900mm. Connection to the 

base is made on site by applying epoxy resin to a conventional socket / spigot butt before insertion into the opening 

of the precast manhole. 

Bases are traditionally constructed manually in-situ using ready mix concrete which is troweled to form the base and 

benching. This practice is labour intensive and requires optimum site conditions to achieve a quality result. The 

Easi-Base precast alternative removes many of the variable factors in the manual process. 

Benching and channels are generally pre-formed with concrete, but glass reinforced plastic (GRP) linings are 

available for special applications on request. The DN 1500 and DN 1800 units are WRc approved and offer the same 

construction benefits as the DN 1200 Easi-Base.

FPM Tools AutoCAD Toolbar 

by FP McCann 

P29 

The FPM Auto-CAD tool bar is a set of instructions designed and aimed mainly at Civil Engineers, 

Quantity Surveyors and estimators used to produce quick and accurate ‘drainage take offs’. 

It provides tabular data for the drainage layout, and specifies the relevant FP McCann Precast ‘Easi- 

Base’ range of products automatically. 

Designed in conjunction with Micro Drainage's 

WinDes software package, the FPM Tools toolbar is 

used to work through the drainage plan in sequence 

specifing each manhole in turn. Manhole references, 

invert levels, cover levels, pipe types and pipe 

lengths are all recorded. When complete a table is 

generated within the actual plan. This table can then 

be exported as a .csv file and opened in excel or other 

supporting program. 

From within AutoCAD, the Manhole Edit tool 

can be used to assemble the manhole and pipe 

data at a particular manhole reference within 

the plan. 

The screenshot above shows the drainage table 

generated within AutoCAD and the exported 

Excel table ready for the quantity surveyor / 

buyer /estimator to send out for pricing.

Easi-Pit (DN 1050 Catch-pit) 

P30 

DN 1050 Precast Catchpit 

The DN1050 catchpit effectively provides a sealed sump manhole, a monolithic precast 

concrete unit fitted with connector seals which can be used to connect to the following 

types of pipe: uPVC, twinwall, clay, ductile iron and concrete. The catchpit is designed 

to accommodate pipe sizes DN150 to DN450. The catchpit is designed in line with 

highway specification. 

FP McCann can produce catchpits upto DN375 in a straight through orientation (180 

degrees). 4-way units with orientations at 90 degrees can be produced upto DN300 

only; beyond DN300 4-way orientations are not available. DN450 inlets must be cored 

onsite. 

Easi-Pit weight 1.38tonnes. 

Benefits of using the DN1050 catchpit unit 

• Creates an immediate watertight structure 

• Cost benefits with reduction in construction time and resource requirement 

• Economically advantageous as limited wet trades are required in the manhole 

construction 

• Accommodates connection to all types of pipe used in road and manhole 

construction 

• Safety benefits gained in the construction of manholes as the pre-formed sump 

and connector seals eliminate on site construction, thus greatly reducing labour 

activity within the manhole 

• Increased confidence to meet industry standards 

• Quality is greatly increased as construction is within the factory environment 

• Eliminates material wastage associated with current in-situ method 

• Yields environmental benefits with less concrete used on site and less excavated 

material removed from site

Easi-Flow Chamber 

P32 

The FP McCann Easi-Flow chamber combines an integral base and side walls 

with provision for inlet and outlet connections. It can be used in a number 

of applications, including: 

• As a silt-trap; 

• As a valve chamber; and 

• As a flow rate controller (requires installation of a vortex valve unit, sold 

separately). 

Sizes available 

Easi-Flow chambers are available between DN1200 - DN2400. 

Flow rate control 

FP McCann can offer supply of a Hydro-Valve vortex flow control device. The 

Hydro-Valve is designed to limit storm water outflow to a specific discharge rate. 

Sizes are available between 1 – 140 l/s depending on head height. The unit is self 

activating with no need for an external power source and comes with a certified 

flow rate. 

The Hydro-Valve is a device for controlling storm water flow by hydraulic effect 

without requiring moving parts. At low flow rates, water entering through the 

inlet passes through the vortex chamber to the outlet with no restriction. As 

flow rate increases water enters through the inlet with enough energy to create 

a vortex in the vortex chamber which results in a considerable pressure drop 

between the inlet and the outlet restricting the flow to the allowable discharge. 

The Hydro-Valve therefore operates automatically with no moving parts and no 

external power source. A typical application of this valve is to control the flow 

from storm water attenuation tanks preventing downstream flooding during periods of heavy rainfall. 

The Hydro-Valves are custom designed to achieve a specified design flow rate at a given head height. 

They are manufactured under an ISO 9001 quality assurance system and are available in sizes compatible 

with the FP McCann Easi-Flow chamber range. 

Hydro-Valve - Customised Specification 

• No moving parts 

• Self activating 

• Self cleansing 

• Manual by-pass 

• Easy installation 

• 3-6 times greater orifice CSA 

• Hydraulic data available 

For more information on Hydro-Valves contact a member of FP McCann technical sales. 

*FP McCann advise not to complete the manhole construction until the JFC flow control device has been 

positioned correctly inside.

Handhold & Entry Pole System 

P34 

Summary 

The handhold entry pole system is suitable for aiding maintenance engineers in the initial 

entry into a manhole from the surface level. Once fitted, the entry pole is a permanent 

fitting in the manhole which is stored in the lowered position beneath the level of the 

cover. When required, the entry pole can be easily extended by simply hooking the easy 

to reach loop located at the top of the pole, pulling the handle upwards and twist locking 

into position. The handhold then provides a stable support to aid the entrance of the 

manhole as well as a clear visual indication of the location of the manhole when open. 

This helps prevent injury of other people in the area. Once the engineer has used the 

entry pole to aid their return to the surface, the pole is simply twisted to unlock it from the 

raised position and lowered back into the manhole ready for the next time it is needed. 

Specification 

The handhold has a pole length of 1200mm and can be assembled to give three different 

distances from the pole to the wall. This is designed to accommodate different cover 

positions 

Advantages 

• Helps the user find the first step safely. 

• Creates visual aid to indicate location of manhole to other people in the area. 

• Easy to fit. 

• Easy to raise and lower. 

• High strength for ultimate safety. 

• Low cost

Easi - Storm Attenuation Systems 

P37 

The production of water impermeable surfaces in construction is 

inevitable. This includes roof areas on buildings, car parks, loading 

bays and road pavements. The provisions of these surfaces interrupts 

the natural drainage process, creating increased stormwater runoff in 

respect of both volume and flow rate. 

In many cases this increase in stormwater flow and volume is a problem 

as the local sewer or watercourse does not have the sufficient capacity 

to cope. This problem could be alleviated by an increase in the size 

of the stormwater sewer or watercourse, thus providing the capacity 

within the drainage system to cope with the increased surface water. 

This however may be expensive, cause major infrastructure disruption, 

and may often be completely unfeasible. 

Legislation under Planning Policy Statement 25 and Building 

Regulations approved Document H3 for flood risk assessment (SUDS), 

has created the need for planners and developers to design and install 

effective storm water management systems. 

The types of system that can be employed to overcome these 

issues are well documented and varied. Quite often, they can be 

very technically demanding in their operation, maintenance and 

construction. The selection of a system will depend on site constraints, 

position, expected loading, geographical limitations and inevitably 

cost. 

The Easi-Storm system offers a complete solution to the stormwater 

attenuation problem and utilises a tried, tested and approved method 

of stormwater storage. F P McCann can provide the complete package 

of design, product specification, supply of products, and advice with 

installation.

· Long term solution 

Design: 

The design of the system can be tailored to suit most structural and 

hydraulic criteria. 

Structural: 

The inherent structural strength of concrete is well documented and 

can be designed to meet the severest of loading criteria. Easi- storm 

systems can be tailored to suit low load situations when the tank is to 

be situated below verges or gardens.

Easi-Hydro Separator 

P38 

Introduction 

FP McCann have designed and developed a new range Hydrodynamic Separators for the treatment of 

urban catchment storm-water runoff¬. The Easi-Hydro Separator provides a cost effective solution for 

designers, engineers and contractors involved in the provision of sustainable urban drainage systems. The 

Easi-Hydro Separator has no moving parts, requires no power and is constructed in precast reinforced 

concrete. All internal components are manufactured in GRP and stainless steel ensuring long asset life. 

The Easi-Hydro Separator has been independently tested by WRc and total solids removal rates range from 

85 to 92% have been measured. The Easi-Hydro Separator is also effective in the removal of hydrocarbons, 

litter and other storm-water debris. 

Operation 

The Easi-Hydro Separator is specifically designed to remove suspended solids, hydrocarbons and floatable 

debris from the storm-water runoff. The Easi-Hydro Separator chamber is constructed in pre-cast reinforced 

concrete and supplied complete with a unique, factory installed, GRP flow management module. This 

unique design produces low energy vortex flow patterns allowing the solids to settle to the bottom of the 

treatment chamber for subsequent removal. Re-suspension of the solids is minimised by provision of a GRP 

baffle plate positioned above the solids storage sump. Floatable debris is retained within the Easi- Hydro 

Separator and prevented from discharging by a dip outlet pipe and launder channel arrangement. 

Flows to treatment are controlled by a specially designed launder channel and inlet pipe arrangement. 

Flows in excess of the maximum treatment flow overflow a weir, bypass the treatment zone and directly 

discharge through the outlet pipe. This helps to minimize the effects of scour within the treatment 

compartment and optimises the performance of the unique Easi-Hydro Separator.

Easi-Rain Harvesting Chambers 

P40 

Easi-Rain by FP McCann is a bespoke range of precast water storage chambers that are compatible with water 

harvesting systems for residential, industrial / commercial and agricultural installations. Capturing rainwater for re-use 

offers significant cost savings for the user and benefits the environment by increasing water resources and further 

enhancing water amenity. Easi-Rain complies with Environment Agency SUDS (Sustainable Urban Drainage System) 

directives. 

The basic concept of harvesting rainwater is simple - rainwater is mostly collected from the roofs of buildings - it flows 

by gravity through gutters and downspouts and is then filtered and collected by a storage tank. From the tank it can 

be recirculated or treated to produce a better quality of recycled water.

Caisson Units 

P46 

FP McCann manufactures a range of reinforcing units suitable for sinking by the caisson method. Caisson shaft 

units can be supplied with diameters of 2100mm up to 4000mm. Caissons are manufactured in accordance with 

the requirements of BS EN 1917, and have Kitemark certification where relevant to the scope of BS5911 (2100mm – 

3000mm diameters). However 3600mm and 4000mm diameters remain operative within the scope of the ISO9001 

accredited Quality Management System. 

Open caisson-sinking techniques permit a shaft structure to be progressively sunk, either under its own weight or 

with the aid of caisson jacks, in a controlled manner from the surface to a predetermined depth. Caisson shafts are 

constructed using a metal cutter ring and base section with rings being added on top as excavation proceeds. The 

technique is suited to shaft construction through weak soils, high-plasticity clays, silts, sands and gravels; particularly 

below the water table.

Power Infrastructure Cable 

Ducting Systems 

FP McCann offers a specialist range of precast reinforced concrete cable troughs and ducting systems used to house 

and protect most types of services, including power and communication cables and pipes for gas, water and chemicals. 

Easi-Duct access troughs and ducts can be buried underground, located above, or flush with surface levels to provide 

protection against accidental or malicious damage and to offer easy access for maintenance and repair. 

Three types of flush fitting lids are supplied in either reinforced precast concrete, GRP composite, or steel tray. All are 

designed and tested for loading group class to BS EN 124. 

Typical Easi-Duct applications include; rail and highway infrastructure; power stations; gas, oil and chemical installations; 

industrial, commercial and domestic developments; docks and harbours; water and sewage treatment plants. 

Benefits 

Compared with the alternatives of direct burying of cables and pipes or overhead suspension, Easi-Duct has a number 

of advantages:- 

• Carries multiple services for different utility providers 

• Non conductive to electricity 

• Chemically resistant concrete 

• Cables buried at depth are unexposed to weather changes (i.e. freezing or overheating) 

• High strength load bearing units 

• Easy access for cable repair, splicing or new cable additions 

• Whole life costing of precast concrete is lower than other forms of ducting construction 

• FP McCann can produce specialist units moulded to requirement 

Design Features 

The troughs, ducts and lids are designed and tested for load classes A15, B125, C250 and D400. For loadings E600 and 

F900, Easi- Duct systems are designed, tested and manufactured specific to order. 

Standard troughs are manufactured with either a 50mm deep rebate to accommodate a class A or B flush fitting lid, or 

100mm deep to accommodate class C or D lids.

From our recently extended factory at Cadeby, we combine over 30 years experience to provide an extensive range 

of attractive, durable and practical fencing solutions. 

The range includes: slotted posts, with gravel boards to suit; morticed posts; recessed posts; chainlink posts; universal 

posts and screed rails. 

Our gravel boards are available in a selection of attractive designs including brick and rock-faced patterns. 

Concrete fence posts are becoming a popular alternative to wooden posts, offering greater strength and durability, 

and of course, will last much longer. 

We also manufacture a range of lightweight products - Fenn-Lite - ideally suited for one-man installation, but with 

the same strength and durability of our other products.
