System’s information
2.1 General information
Trade name:
PROTEA DUO TRIARMATO and MINERAL PROTEA DUO TRIARMATO
Composite waterproofing membrane manufactured from:
♦ Upper layer elastoplastomeric polymer bitumen
♦ Composite “non woven” spunbond polyester fabric impregnated with elastomeric polymer-bitumen
♦ Lower layer elastomeric polymer-bitumen.
DESCRIPTION
PROTEADUO is a composite waterproofing membrane where the reinforcement is impregnated with SBS
bitumen. The lower face which comes into contact with the substrate is made from SBS modified bitumen
while the upper face is made from the APP modified bitumen The elastomeric coating medium of the lower
face contains distilled bitumen and thermoplastic rubber made from a block copolymer radial, styrenebutadiene-styrene.
The elastoplastomeric coating medium, which makes up the protective layer of the upper face of the
membrane, contains distilled bitumen, atactic polypropylene, isotactic and polyolefinic elastomers resistant to
U.V. rays, with added stabilisers for thermal shock, and a softening point above 150'C.
The reinforcement is also the result of careful researches into the strengthening of waterproofing
membranes. As it is well known, non-woven" polyester , while being resistant and elastic, it is more sensitive
Page n° 3 out of 24

to the temperature then the mineral fibers reinforcement and can be the cause of deformation of the
membranes.
The traditional use of the non woven polyester in combination with glass fibers solves the problem of stability
but even at the application stage the bending of the membrane causes tiny breakages in the glass fibers,
which can damage the bitumen covering.
PROTEADUO TRIPLE REINFORCEMENT has a composite three-layer reinforcement, where the glass fibre
fleece is contained between two layers of continuous strand "non woven" polyester. The glass fibre fleece
guarantees dimensional stability and the bituminous mass is protected and reinforced by the ”non-woven"
polyester. The dimensional stability of PROTEADUO is very similar to that of glass fibre reinforced
membranes while maintaining the good elasticity characteristics of "non-woven" polyester avoiding, in this
way, the bending problems due to the combination polyester-fiberglass mentioned above.
The reinfocement is completely impregnated and coated in the elastomeric coating medium by an exclusive
procedure, which guarantees absolute waterproofing, high tear and impact resistance and excellent elasticity
even at low temperatures.
The lower face of PROTEADUO is covered by an anti-adhesive Flamina film, which has high retraction when
it comes into contact with the torch flame during application.
The elastomeric layer ensures excellent adhesion on most ordinary construction materials, and on
polymer-bitumen membranes

control service, know all the information about the production of the material.
Page n° 5 out of 24

TRANSPORT
Rolls of the waterproofing material are grouped on pallets and covered with thick, shrink-wrap polyethylene
sheeting. However, long journeys on bumpy roads or sharp braking, especially during summer months or on
a long trailer, can cause the rolls to tip over. Ropes tied between the rows and across the sides of the trailer
can prevent this occurrence. The ropes should be pulled tight and padded so as not to leave imprints on the
rolls.
LOADING / UNLOADING
INDEX membranes are made to resist the mechanical stress they undergo during application. However,
handling operations should be carried out with care to prevent squashing or contact with sharp or pointed
surfaces. During low temperatures, sharp impacts should be avoided which may cause the membrane to
break.
STORAGE
The materials should be stored under cover. The rolls should always be stored vertically on a smooth, flat
surface except for those supplied with a rigid, internal reinforcing roll or support which can be placed
horizontally for a limited period under cover. Also under cover, pallets can be stacked two high provided
wooden planks are interposed to distribute the weight evenly.
HANDLING ON SITE
Only keep on site the number of rolls necessary for the day's use. Place the rolls upright on a flat, smooth
surface. Use a crane and suitable lifting attachment to lift the rolls onto the roof on a pallet in good condition.
If it is necessary to open the packaging and lift the rolls onto the roof separately, use the correct crane
accessories, then stand the rolls upright. Do not use ropes to tie and lift the rolls.
CONSERVATION
Pallets should be stored in a dry location out of direct sunlight. During summer, pallets with shrink-wrap
covers left in the sun can quickly reach temperatures of 70°C and that causes progressive blackening of the
surface or slate chips on the rolls from the top to the bottom until the membrane starts to stick to itself or until
it looks unattractive.
If it is necessary to store pallets in the sun, even for short periods, it is better to remove the covering
completely or at least to make slits in the sides for ventilation and protect the top with wooden planks or
laths. In wintertime the rolls should be left in a temperature above +5°C for 24 hours before laying but should
not be left in the open-air overnight. Only those, rolls that are to be laid during the day's work should be
taken to the site. A good practice is to always take the oldest rolls from the store and not to leave any rolls
stored for more than 12 months.

INDEVER
BITUMINOUS SOLUTION CONTAINING BITUMEN AND QUICK-DRYING SOLVENTS
INDEVER MOTORWAYS
BITUMINOUS SOLUTION CONTAINING BITUMEN AND OUICK-DRYING SOLVENTS SUITABLE
FOR APPLICATION ON DAMP SURFACES
DESCRIPTION
INDEVER is a bituminous primer made from a mix of solvents and oxidised bitumens. If applied as a thick
waterproofing paint, when dry, INDEVER leaves a strong anchorage on every type of substrate without any
degree of surface stickiness. It also has excellent penetration, adherence and consolidation properties when
applied to dry concrete surfaces.
INDEVER MOTORWAYS is a bituminous primer made from a mix of solvents, oxidised bitumens, and
selected additives to improve anchorage to even damp concrete decks. INDEVER MOTORWAYS complies
with technical motorway specifications for applications on concrete bridges and viaducts before polymer
bitumen membranes are applied.
APPLICATIONS
INDEVER is suitable for saturating a cement deck in addition to preparing an excellent anchorage for
bituminous waterproof coverings or polymer-bitumen membranes.
INDEVER fixes superficial cement dust providing excellent adhesion of the waterproofing layers, which
require strong, permanent adhesion to the support.
INDEVER is specifically used for applications on dry concrete viaducts and bridges before a bituminous
polymer membrane is laid down.
INDEVER MOTORWAYS performs all the same applications as INDEVER primer but is specifically designed
for use on damp surfaces.
DIRECTIONS
Preparation of the concrete substrate
For best results, the concrete surfaces to be treated should be as dry as possible where INDEVER primer is
used and slightly damp where INDEVER MOTORWAYS primer is used. All surfaces must be perfectly clean
without loose particles and free from oil, grease and dust.
APPLICATION
Both INDEVER primers are ready to use and do not need diluting; they are applied by brush, broom or
spray.
The quantity of INDEVER primer to be used depends on the surface porosity and the type of finish of the
surface to be treated. Polymer-bitumen membranes may be applied after a drying time, which varies from a
minimum of three hours, in situations exposed to the sun, up to eight hours in diverse conditions.
Consumption per coat on cement surfaces: 350-500 g/m² Consumption per coat on metal surfaces: 200-300
g/m².

INDECOLOR
Water based protective and decorative coating for use on bituminous waterproofing.
Indecolor is a waterproofing paint containing polymers dispersed in water with internal plastification. Once
dried, Indecolor forms a flexible tough skin, which adheres well to polymer-bitumen waterproofing
membranes.
Application may be carried out by brush, broom or spray. Surface to be painted must have a slope of at least
3% to allow rainwater drainage; Indecolor is not suitable for finishing flat roofs where ponded water may be
present.
For a good result it is necessary to apply two coats of Indecolor paint. The second coat should only be
applied after the first coat has dried; this is usually after approximately 24 hours.
Coverage per coat is about 300 g/m².

SOLARIS
Solaris is a paint containing a particularly fine metallic aluminium powder, resins, polymerised oxidised
bitumen, plasticisers which do not seep, reflective fillers and special solvents. Solaris is a brilliant silver
colour and is of fluid consistency.
Once dry, it forms a waterproofing protective film, which reflects the sun’s rays, contributing appreciably
towards thermal insulation of the protected areas, and reduces solar heat build up inside the building.
Solaris is ready to use and is applied by spry, roller, brush or broom. One coat is sufficient for complete
coverage to provide a reflective surface to the bituminous surface, but two coats are recommended where
longer lasting and improved protection is required.

PERFOBASE
Perfobase is a perforated reinforced glass fibre felt impregnated with polymer modified bitumen. A sacrificial
polyethylene film protects both sides of the membrane, which is heat melted. The perforations, each 40 mm
diameter, are distributed evenly throughout the membrane, with 119 holes per square meter.
It is use for to obtain a partially bonded surface evenly distributed, in which the area of adhesion is
approximately 15% of the total surface. It allows vapour to disperse and movement of the deck under the
waterproofing layer to take place without damage to either the Perfobase or the cap sheet.

3 rd Section
Application’s information
Loose laid application
By “loose laid” we mean application of waterproofing system completely detached from the substrate: this
method cannot be used for slopes higher than 5%, as a heavy protection is always necessary (with gravel or
concrete tiles); moreover, this system is advisable when the membrane is applied on thermal insulating
panels. Perimeters and parapets and vertical walls are always fully bonded by torching. In case of doublelayer
application, the second layer is fully torched to the first one, keeping the first layer staggered 50 cm
from the second one.
Partially-bonded application
When “partially-bonded ” the waterproofing systems must be adhered using a predetermined ratio to give an
even application over the total surface area. On concrete substrates, the surface has to be treated with a
primer and spot-torched afterwards, in order to obtain a bonded surface for 50% of the whole. This way of
application is advised for slopes up to 40%. Perimeters and parapets and vertical walls are always fully
bonded by torching.
Alternatively, we may suggest the use of perforated membrane “Perfobase” for slopes up to 20%; for higher
slopes the use of mechanical fixing at the end of the roll is advised.
In case of non continuous concrete substrates, in between the substrates itself, stripes of at least 20-cm
width have to be mechanically fixed (and/or by torch) to one of the two adjacent elements. Where a doublelayer
system is requested, the second of these layers is fully torched on the first, keeping a staggered of 50-
cm between the membrane of the first and second layer.
On substrates made of thermal insulating panels, a bituminous fibreglass felt weighing 1500 g/m2 has to be
applied as a first layer. This should be spot-bonded using hot oxidised bitumen 85/25 for slopes up to 5%, or
100/30 oxidised bitumen type for slopes between 5 and 15% , in order to obtain a minimum bonded surface
equal to 50% of the whole surface.
Afterwards, the membrane has to be completely torched. Alternatively, we may suggest the use of “Defend
3” or “Helasta V3” for slopes up to 20%, whereas for higher slopes a mechanical fixing of the heads of the
rolls will have to be considered. For application on thermal insulating panels with bitumen treated surface,
the perforated membrane “Perfobase” could be used, by fully torching the waterproofing layer afterwards.
The vertical borders and perimeters are always carried out by fully bonding.
Fully bonded application
By “fully bonded” we mean application where the membrane is fully adherent to the substrate. In case of
discontinuous concrete elements and load-bearing concrete element substrates, please refer to the chapter
above, except for bonding that has to be done on the whole surface.
Similar systems are considered for application on substrates made of thermal insulating panels, stressing
that bonding of bituminous fibreglass felt or of the membrane has to be fully adhered. Alternatively, we may
suggest to using membrane “Defend 3” or “Helasta V 3” fully bonded. This way of application is advised for
slopes up to 40% on concrete substrates and up to 20% for substrates made with thermal insulating panels.
For larger slopes, a mechanical fixing on the head of the rolls will have to be taken into consideration. In
case of double-layer application, the second membrane is fully bonded on the first, ensuring the two layers
are staggered of 50cm. This kind of application must be used next to dumping area, vertical borders and
expansion joints.
Page n° 10 out of 24

PERIOD OF USE AND CLIMATIC CONDITIONS
RAIN SNOW HUMIDITY
Rain, frost, snow and high humidity can all affect the adhesion of the membrane to the laying surface and
overlaps. At temperatures lower than +5°C, it is probable that ice will be present on the surface to be
covered and the rolls will unroll with greater difficulty. Also, the dampness trapped between the membrane
and the laying surface may give rise to blisters. In such cases, it is better not to lay material. In summer, in
hot countries, and especially when rolls are being laid on thermal insulation, it is better to apply the material
during the coolest part of the day avoiding the midday period.
SMOOTHING
The laying surface must be smooth and flat. A concrete surface is acceptable if no
bumps greater than 10 mm. are found under a 2 m. rule in any direction, and no
bumps greater than 3 mm. are found under a rule of 0.20 m. The surface should be
trowelled and all cracks and gaps should be filled with mortar.
Any projections and site residue such as nails, sheeting, bits of wood etc. must be
removed.
WATER, ICE
The laying surface must be clean and dry before application. Laying surfaces made
of concrete or concrete tiles should be left to dry for between 8 days and 3 weeks
depending on the season.
CONCRETE LAYING SURFACE
Once above mentioned points have been carried out, INDEVER bituminous
adhesive primer is spread on the areas where the membrane will be anchored .
The primer carries out the important functions of preparing the receiving surface
and increasing adhesion. Leave to dry for between 2 and 24 hours.
Page n° 11 out of 24

TIMBER LAYING SURFACE
Sheets of bituminised paper or ROLLBASE should be fixed to timber surfaces with
large head nails to protect the wood from the torch-flame. Then the membrane
should be bonded using the total adherence principle.
LAYING ON TOP OF OLD APPLICATIONS
If the condition of the old application allows it to be retained, it can be used as a
substrate Perished and weakened areas must be removed and blisters must be
flattened. Spread a layer of INDEVER primer before the application of Index
membrane.
LAYING ON NON-HEAT SENSITIVE PANELS
Two possibilities exist: torching directly onto the upper surface of
pretreated panels made on purpose for this type of application;
alternatively, applying it on top of bituminised glass-fibers felt stuck
to the panel with hot blown bitumen
ALIGNMENT OF THE SHEETS
Unroll the sheet and align it by overlapping the edge on the nearest sheet. Then
partially roll it up again from both ends and start the flame-bonding process.
Take care to do not create points where 4 layers are coming together, in other
words do not align the head of the rolls or do not place two layers exactly one
above the other.
Page n° 12 out of 24

UNROLLING SHEETS AT LOW TEMPERATURES
When temperatures are low, do not bang the rolls or unroll them in a way that
may damage the membrane. Unroll them with care and without kicking them.
MEMBRANE SURFACES
The underside of the sheet is the surface to be treated. It is embossed with squares and lined with a thin film of
FLAMINA.
When heated, the FLAMINA film melts to indicate when the material is ready for bonding. The upper side of the
membrane is covered with TEXFLAMINA (“non woven” PP) This helps to ensure the wrapping detaches even at high
temperatures.
TORCHING
Polymer-bitumen waterproofing membranes bond with the application of heat and
do not require materials such as solvents, adhesives etc. Use of a propane gas
burner is used to heat the sheet to make it adhesive. As the material is heated, the
Flamina film retracts, the upper side blackens until it takes on a shiny appearance,
the embossing flattens down, the surface becomes shiny and the membrane is
ready to be bonded to the support and overlaps.
The INDEX trademark is printed in white on the flamina film, which disappears to indicate retraction has reached the
correct point. Flame heating causes the film to retract and the embossed pattern to flatten; further heating can cause the
polyester reinforcement to be damaged, which melts at 260°C, and causes shrinkage, waving, curling and, in the worst
case, will burn holes in the material.
On the other hand, insufficient heating will not bond the material adequately to the surface, between layers or on
overlaps.
When the material is applied on insulation board with a slope > 20% is necessary to provide a mechanical fixation for the
head of the rolls, if, there is no insulation board is possible to reach a slope of 40% without having a mechanical fixation.
Without insulation is possible to reach slope higher then 40%.
OVERLAPS
Overlaps have to be always welded by torching and pressing down, they have to be 10 cm wide longitudinally (side laps)
and 15 for the roll’s heads cm (end laps).
SEALING OF OVERLAPS, WHAT NOT TO DO
Sealing of overlaps with a trowel, spatula or other tools has been shown to do more harm than good. First, it nicks and
therefore weakens the membrane reinforcement, and often the upper protective layer is removed and the reinforcement
is left exposed.
It often happens that operators bond only 1 or 2 cm. of the overlap hoping that sealing of overlaps will create an
adequate seal but they do not realize that such little bonding does not create enough adhesion for the overlap to be
sealed. In the end, time is lost by having to rework the overlap.
Page n° 13 out of 24

It is safer and faster to bond the overlap correctly the first time while the sheet is being unrolled, making the molten
coating medium leak out of the overlap, which will seal the overlap once and for all.
SPOT BONDING
PERFOBASE is a perforated sheet, which is laid dry on a laying surface pretreated
with INDEVER PRIMER. It allows the overlaid membrane to be spot bonded
uniformly through the holes. Alternatively, the membrane can be spot bonded
during unrolling, locating the spots evenly. Special care should be taken in bonding
head-to-tail overlaps.
MULTI LAYER SYSTEMS
When the waterproof system consists of two or more layers, it is
essential that they adhere well one to each other.
There is no justification for less careful application because the
covering has more layers. If so, the same risks for poor laying are
run as for a single layer. If the layers are not bonded well to each
other, water will find its way from the external layer through the
innumerable channels created between the layers until it finds a
weak spot in the join of the layers below and give rise to a leak.
Effectiveness of a multi-layer covering is guaranteed only by
complete adhesion between all the layers.
TORCHING ON VERTICAL SURFACES
INDEX membranes have excellent resistance to flow and do not slip even if bonded to
a vertical surface. By flame-heating both the membrane and the bonding surface, the
material will hold tenaciously without need for mechanical support. The sheets "take"
when they cool, i.e. when the molten adhesive compound turns solid again.
In summer, the membrane and bonding surface may be so hot that it is necessary to
wait for a long time until cooling takes place and the material holds. If this happens, the
operator is obliged to hold the material up with his hands until cooling occurs; if he
doesn't, the sheet will not stay attached and will fall. For vertical walls without
insulation higher then 1 m is necessary a mechanical fixation of the roll’s head, with
insulation material is necessary when is higher then 50 cm.
Detached sheets should not be reheated immediately in another attempt to attach them to the surface; instead, the
operator should wait for them to cool. If not, the sheet will never cool and will therefore not succeed in sticking to the
surface.
Summary: the sheet and laying surface are both heated for vertical applications, and the material is held in place until it
cools enough for adhesion to take place.
Page n° 14 out of 24

TYPICAL FLASHING DETAIL
If no seating has been created for the covering on a vertical wall, a
metal flashing will have to be nailed and sealed above the edge of the
sheeting. The membrane must be completely bonded to the laying
surface along the edge of roofs and on the flat. If insulation is present
it is necessary to nail the head of the membrane too.
PROTECTED PROJECTIONS
If seating has been created for the covering, the material is bonded there and
then covered with a metal or glass net to which the plaster anchors it.
PROJECTIONS WITH FLASHING
If the waterproofing system is to be bonded to the perimeter walls, these will
then be covered with nailed flashing.

Particular care should be taken that overlaps do not leave holes or cuts exposed.
PAINTING
Protective paint should be spread with a roller crossway in two layers. A
Brush can be used for small areas or details. Depression on a roof will
cause pools of water to form, which may rise to paint coming loose.

A 20-mm thick bed of sand will be laid on top of the waterproofing system previously applied. The sand
will be covered by a 1-mm thick polyethylene sheet or by 300 g/m² bitumenised felt. The whole area will
then be levelled by the application of 4-cm thick layer of concrete based on 350 kg of Portland 325
cement for cubic meter of mix. Where the floor needs to be reinforced, a bigger thickness of the levelling
layer could be foresees. In all cases an opportune number of expansion joint has to be incorporated.
2. Protection layer of gravel.
On the top of the membrane 200 g/m² non-woven polyester should be dry-laid down allowing for 100
mm overlaps. Finally a layer of cleaned and rounded gravel having a granule size of about 16÷32 mm
should be evenly laid down. Usually gravel’s thickness of 4÷5 cm is used.
3. Floor in prefabricated paving slabs
The paving slabs will be a minimum of 30-mm thick and 400 x 400-mm in size. The slabs should be laid
using plastic support (like HELASTORING) which will rest directly on the waterproofing membrane.

Production description
Bitumen is supplied in a liquid phase from the refineries and is stored in heated tanks. For the preparation of
the new compound it is transferred to a balance weight and then pumped into vertical mixers. Distinguished
mixers are kept for SBS and for APP compound. Here, weighted polymers and inerts are added and mixed
together.
When the compound is homogeneous it is transferred to a holding tank and finally to the impregnation bath
pipelines and impregnators baths are reserved for only one type of compund.
The reinforcement comes into the melt compound and becomes impregnated.
A constant thickness of compound on the bottom side is guaranteed with a special device, later on, a layer of
APP compound is spread on top of the membrane, and the total thickness is then controlled with another
dedicated device.
The membrane is then cooled down with several water baths, during this operation different type of surface
finishing could be done (flamina, sand, Texflamina, slates etc).
The final part of the production line involves rolling up, cutting into the right length and packaging the
membrane with proper tape.
A standard roll measure is 10 by 1-m and it is packed with two coloured tapes which show identification trade
name thickness and production site.
Each roll is marked with adhesive ticket-control with a recorded number, which allows the quality control
service to identify the production lot.
All the operations are made automatically and the rolls so finished are sent to palletizer machine, where a
shrinkable bag is put on the pallet.

Quality control
The quality control plans :
♦ raw materials
♦ Bitumen: Penetration at 25°C and Ring & ball.
♦ APP: Compound with Bitumen’s witness sample.
♦ SBS: Compound with Bitumen’s witness sample.
♦ Reinforcement : Tensile strength elongation and mass per unit area.
♦ Filler: granule size, nature.
♦ Granules Slates: granule size
♦ during production
♦ Ring & ball
♦ Self protecting appearance
♦ Width
♦ Self protecting width.
♦ final product
♦ Thickness
♦ Cold bending
♦ Heat resistance
♦ Dimensional stability
♦ Composition by extraction
♦ Loss of granules
All the tests are made according the requirements described in the UEAtc directives specific for APP and for
SBS compound.
Six people are working in the laboratory with a specific preparation in chemistry.
The laboratory is equipped for all the tests:
♦ Ovens
♦ Cooling chambers
♦ Dynamometer
♦ Viscometer
♦ Accelerating weathering test
♦ Water baths
♦ Puncture resistance device
♦ Softening point
♦ Dimensional stability
♦ Etc.
All the calibrations are made yearly, according a specific ISO 9001 procedure. An external body calibrates
balances Viscometer and Dynamometer. A certified reference thermometer, weight and viscous fluid are
available for calibration.
