Casali S.p.A. has been dealing in the field of waterproofing for the building trade

since 1936.

The company started off with rolled bituminous paper felt products but in 1976

turned to the production of torched-on bituminous-polymer prefabricated mem-

branes, an all-Italian invention that in very little time was to be used all over theworld and today still represents the ideal solution for the most common applica-

tions such as flat and sloped roofing, bridges and viaducts, below ground applica-

tions and roof gardens.

Close liaison with customers and tailor-made solutions to their specific require-

ments are the cornerstones of Casali's philosophy;strict testing, efficiency and qua-

lity are its strong points. In an endeavour to meet these requirements and changing

market needs,Casali keeps ahead of the times with targeted products and services.

In 1992 the Membrane Division (with over 400 different types of prefabricated

membranes) was extended with the introduced of the Synthetics Division for the

production of liquid waterproofing and paints (supplementary or

optional to traditional membranes), treatments and consolidating

products for the building trade, special industrial and sports flooring

and coverings.

The family of Casali products continued to increased over the years,and in 1995 the Company acquired the French Brand MANTOLAMI-

NA, well-known for its high quality and featuring a copper or alumi-nium lamina finish that provides a total barrier against exposure to UVrays, evaporation of plasticizing oils etc. as well as a beautiful finish.

Casali has more than thirty years of experience oninternational markets.Thanks to partnerships crea-ted for product distribution and marketing, theCompany is present in many countries all over theworld.Casali S.p.A. is located in Italy.Thanks to its efficient

organisation the Company offers excellent leadtimes and prices for projects and products alike.The two production facilities on an area of 23.000sq.m. (9.500 sq.m. under roofing) are a stone'sthrow from Ancona Airport and just a few kilome-tres from Falconara Marittima Railway Station andthe Ancona Sea Port.

The experience acquired by Casali S.p.A. onworld markets and products and the introductionof innovative production systems, allow theCompany to provide tailor-made solutions to

specific roofing problems as well as reliable andconstant quality which is guaranteed by a strict,

round-the-clock monitoring system. In 1996 Casali's QualitySystem was awarded UNI EN ISO 9001 certification.

Much of the company's success on the domestic and foreignmarkets is however also due to the enormous resources investedby Casali in R&D that have allowed the company to keep one stepahead of developments in production techniques, waterproofingproducts and the building trade developing its know-how to impro-

ve the quality standard of processes and products. Highly qualifiedstaff and labs equipped with the most modern and sophisticatedequipment bear witness to all this.

3. TECHNICAL TERMS - GLOSSARY

This section provides the definition of some the technical terms used in this Guide.These terms, which are often used by operators in the sector, are also used in technical specification, directives and test descriptions.

Cover ing A technological unit that contributes to realizing a specific ambient and use beneath itself with respect to external ambient and use.

Drainage layer

Directs the flow of runoff water in covering systems. Generally consists of suitably sized washed gravel.

F i l t er ing Layer

Holds back dusty material without impeding the runoff of rainwater.

Laying surface

Suitably prepared surface on which the covering components are applied.

Pr iming layer

Layer used to promote adhesion between the laying surface and the components applied on the same, generally by means of a bituminous

primer applied by roller or brush.

Protect ion layer

Protects the covering from physical, chemical and mechanical stress. Protection layers may be light or heavyweight or self-protecting accor-

ding to the intended use.

Root stop layerProtects underlayers from the penetrating action of roots on roof garden coverings. Generally consists of a special bituminous membranecontaining a compound treated with chemical root stop additives.

Slope layer

A layer normally realised in hollow cement that gives the covering a minimum incline for the runoff of rainwater.


14/10214

St i f fen ing Layer

Uniformly shares the loads concentrated on the layers below.Generally consisting of a reinforced concrete slab with electrically welded square metal meshhaving a thickness of 4 cm.

Suppo r t i ng e l emen t

Element having the function of supporting permanent loads and overloads on the covering.The supporting element may be realised in reinforced concre-te, pre-compressed concrete, clay-cement mixes, metal, wood etc.

Thermo- insu la t ing mater ia l

Material applied to ensure a particular thermal resistance to the covering as a whole.

Vapour bar r ier layer

Impedes the passage of water vapour in the covering system.Generally, a bituminous membrane reinforced with aluminium lamina is used.

Vapour d ispers ion layer

This layer allows water vapour to transpire preventing pressure build-up under the waterproofing layer. Generally applied under the vapour barrier with abreather vent between the two layers.

Vent i la t ion layer Helps to regulate temperature and humidity levels, through air exchange.

Waterproofing e lem ent

Element used to waterproof the covering from rainwater.The waterproofing element may be realised in many different ways, the most common of whichis by means of a double layer of bituminous membrane.

Water runof f e lements

Any element used to direct the flow and drainage of rainwater such as drainage traps, gutters and rain water pipes.

4. USE OF BITUMINOUS MEMBRANES - APPLICATION PROCEDURE

This section provides useful suggestions on how to use the waterproofing membranes produced by CASALI S.p.A.Applying a bituminous membrane is simple but certain rules must be followed to ensure that the material is used correctly. In order to ensure state-of-the-art results remember that the waterproofing membrane should be applied only by skilled staff in accordance with the proper laying procedures, taking all

the necessary precautions to prevent damage during transport - handling and storage.

4.1) RECEPTION

When checking the material on arrival to ensure that the description on the Delivery Document complies with the material requested, it may be useful touse the "fiscal" alphanumerical code shown on the invoice together with the description of the product.When reporting non conforming material, pleaseremember to indicate the data shown on the label on the pallet and/or the number on the roll.This is the only way for customers to ensure a quick andaccurate response.

4.2) HANDLING AND STORAGE

When stored for a lengthy period of time, the membrane must be protected from bad weather conditions, sunlight and excessively low temperatures.Remember that heavy blows, even on smooth surfaces, may cause tearing, cracking and bending that may compromise the waterproofing efficiency of the

membrane.The lower the temperature, the higher this risk will become.

Pallets should be stacked with care. Black membranes (separated by a rigid plane in order to share the load) must not be stacked by more than two levels.Slated membranes and self-protected mwmbranes with metal lamina must not be stacked at all.

Materials in stock should be continuously rotated bearing in mind that materials delivered for example in January are designed for application at the weatherconditions experienced during that period.This property of the materials becomes a disadvantage if used for example in July. In addition to the above, anextra word of warning goes to the slated membranes where different lots may have different shades of the same colour.

Never wind a rope around the middle of the roll when lifting or moving since the rope may bend or fold the roll. For handling purposes, lift or move thepallet on which the rolls are packaged, removing only the material required for the application.This considerably facilitates operations and work at the site.

If the pallets of membranes are kept in the sun, even for short periods of time, remember to slit the shrink wrapping along the length of the roll at several

points to allow air circulation and prevent hothouse effect overheating of the membrane that might damage the characteristics of the material or blackenthe talc and/or slate.


16/102

4.3) TRANSPORT

During transport, ensure that the pallets are well secured using suitably padded angle bars to impede marks on the rolls. Protect the pallets from tearing,

cuts and heavy impact, above all when temperatures are critical.

4.4) PREPARING THE LAYING SURFACE

4.4.a) Structures in reinforced concrete, clay-cement mix and pre-compressed concrete

- Remove gravel,sand and other matter that might damage the waterproofing membrane or reduce adherence, levelling holes with cement mortar.- In winter ensure that the laying surface has cured properly, that no ice is present and that the laying surface is clean and dry. Do not apply the product

when temperatures are below 5C.

- If the laying surface does not have an incline of at least 2-4%, lay a sloped layer in cement mortar to ensure water runoff of rainwater.

- Apply by brush or roller a 300 ml/sq.m.coat of DERMAPRIMER along the perimeter and on special points as well as on the adhesion surface of the next

layer.When the primer is dry, start laying the membrane.

4.4.b) Wooden structures

- Apply by brush or roller a 300 ml/sq.m.coat of DERMAPRIMER on all the embossments.When the primer is dry, start laying the membrane.

- Dry lay a polyester reinforced membrane on the wooden laying surface, orthogonal to the incline, securing the membrane with wide-head nails spaced

at 33 cm in staggered lines.

P.S.When overlapping the covering in areas exposed to strong winds, we suggest reinforcing the nails by applying a 300 ml/sq.m. coating of ECOMASTIC

to ensure full adhesion of the separation layer, before laying.

4.4.c)Metal structures

- Ensure that the laying surface has no rough areas that might damage the membrane.

- Apply by brush or roller a 200 ml/sq.m.coat of DERMAPRIMER along the perimeter and on special points as well as on the adhesion surface of the next

layer.When the primer is dry, start laying the membrane.

- Along the line where corrugated plate sheets overlap, lay a strip of elastomeric bituminous membrane at least 50 cm wide torching along one edge and

leaving the other side free, before applying the next layer so as to impede from tearing due to contact with the edge and the nails on the sheets.4.4.d) For all applications

- Proper design of the covering must include a temperature and humidity study of the system according to the climatic conditions and intended use; the choi-ce and dimensions of the insulation must be decided according to the results of this study following the application of a polyester reinforced vapour barrierUNDERLAY or an aluminium reinforced + overlay mat vapour barrier VAPOREX, applied as per the procedure described in order to prevent the formationof condensate on the concave surfaces of the covering and/or in the system itself.

4.5 LAYING PROCEDURE FOR POLYMER - BITUMINOUS MEMBRANES

Bituminous membranes may be applied by hot or cold laying procedures.

4.5.1) HOT LAYING PROCEDURE

The hot laying procedure consists of torching on the membrane by means of a propane gas blowpipe.The choice of the laying procedure depends on the

characteristics of the laying surface, the incline of the covering and its intended use.

There are three different types of hot laying procedures:

Loose laid

Partialy bonded

Fully bonded

Loose laid

This procedure consists of simply resting the membrane on the laying surfacing and then fully bonding the longitudinal and head

joints, the perimeters, the vertical embossments, the areas close to the joints and drainage etc.The second layer is always fully bonded onto the first layer,

with the sheets staggered sideways by 50 cm and longitudinally by a half roll.

This procedure is used for flat coverings or those with an incline of less than 5% and in particular when the supporting structure is subject to differential

movements that might damage the waterproofing element.The stability of the covering is ensured by heavy protection such as ballasting with gravel, cement

blocks, cement slabs etc.

Partialy bonded

This procedure is used when the waterproofing element is the finishing or top layer, and it is necessary to provide ventilation and vapour pressure control

on the covering. It is extremely important to calculate the wind pulling resistance of the fixing elements accurately. Uniform spot bonding

may be ensured by using a membrane such as GRUVER with holes, suited to the waterproofing element, that guarantees a uniform density of the fixing

points over the entire surface; this laying system may be used for laying surfaces with inclines of up to 30%.

For major inclines, a membrane with holes should not be used and the surface bonded to the laying surface must be at least 50% of the total surface area.

The compound is torched on by means of a propane gas blowpipe on parts of the under surface covered with the polyethylene film.

Even in the case of partial bonding, the perimeter areas, the vertical embossments and critical points must be fully bonded.

The second layer is fully bonded on to the first layer with sheets staggered sideways by 50 cm and longitudinally by half a roll.


18/102

18

Fully bonded

This procedure consists of bonding the membrane to the laying surface including the lateral and head joints, the perimeter areas, the verticalembossments, the areas around the joints, drainage etc.The second layer is always fully bonded to the first layer, with the sheets staggered sideways by 50cm and longitudinally by a half roll.This laying procedure is used for coverings with rigid supporting elements (clay-cement and reinforced concrete floors), with coverings inclined by morethan 40%, in applications where the waterproofing element is visible and to guarantee the stability of the covering against wind action and that of the ver-tical walls. In this case, use of a polyester reinforced waterproofing membrane with suitable tear resistance characteristics, is recommended. Flame resistantinsulation should be used.

4.5.2 COLD LAYING PROCEDURE

Cold laying procedures are used above all when bonding is not possible but also on metal laying surfaces which are easy to nail or when the membrane islaid on flame-sensitive insulation.These are clean systems that do however require highly skilled labour in that there is very little room for error, above allin the case of single-layer applications.The most commonly used procedures are as follows:a) Self-adhesive membranesb) Membranes applied with bituminous glue

a) Self-adhesive membranesThese are special membranes with a bottom self-adhesive layer generally protected by non-stick silicone paper which is removed before laying.

b)Membranes applied with bituminous glue

A layer of bituminous glue (generally solvent-based) is applied, on which the membrane is laid.

4.5.3 MECHANICAL FIXING

As mentioned previously, membranes are fixed mechanically above all in the case of wind exposure, vertical walls and when flame-sensitive materials areused (above all insulation).The membrane sheets are fixed to the laying surface with flat-head nails and washers.The fixing points are spaced evenly, depen-ding on the type of laying surface, and should be increased at special points and along the perimeters.The nails are fixed under the joint on the longitudi-nal and head overlaps.This system requires the use of membranes that are highly resistant to tearing and with high dimensional stability (laying membra-nes with polyester - fibre-glass thread reinforcement).

4.6 BASIC LAYING RULES

- Check that the sheets are correctly aligned, unrolling them completely and positioning them.

- In the case of flat coverings, always start at the drainage areas, while in the case of highly sloped coverings, the sheets may be placed parallel to the direc-

tion of the slope.

- The side joints must be at least 10 cm, while at the head joint should be approx. 15 cm.

- Roll out half of the roll, then torch the under surface of the membrane, which generally is covered by a polyethylene film, with a propane gas blowpipe,

softening the bituminous mass, and fixing first one half and then the other.

- Pass a trowel or spatula over the overlaps, without reducing the thickness of the membrane or exposing the reinforcement.

- The second layer must be fully bonded on to the first layer, staggering the side overlaps by 50 cm and the head overlaps by half a roll.

4.7 DIFFERENT TYPES OF PROTECTION FOR WATERPROOFING COVERINGS

There are three different types of protection for bituminous waterproofing membranes:

- heavy protection

- light protection

- self-protection

Heavy Protection

Flat coverings (having slope of less than 5%) with loose laid waterproofing must be protected by any of the following heavy protections, according to inten-

ded use:

- Reinforced concrete cast with electrically welded metal mesh that distributes the loads, over a layer of sand of at least 2 cm.

- Marble or tiled flooring in the case of treadable surfaces

- Cement blocks placed on wide-based plastic support

- Self-blocking elements or similar over a layer of sand

- Bituminous conglomerate or asphalting for surfaces suitable for vehicle traffic

- Green roof system for roof gardens

- Ballasting consisting of 15 mm washed river gravel in layers of 4 - 8 cm depending on wind conditions

For all the solutions proposed, we recommend laying a dividing layer between the waterproofing membrane and the overlying structure in high grammage

polyester TNT (250-300 / sq.m.), bituminous paper felt or polyethylene film etc., according to the application requirements.

Light protection

This type of protection is used for black membranes using aluminium or copper based reflecting paints such as REFLEX AR,REFLEX MR or REFLEX Rame

to prevent the natural ageing of bitumen caused by UV rays and to impede the "crocodile skin" phenomenon that appears on unprotected bitumen. This

treatment is indispensable when thermal insulation is laid under the waterproofing element.


20/102

20

Remember that this type of protection requires maintenance every 3 - 5 years to restore the reflecting capacity of the paint that may be damaged by atmo-spheric agents, animal droppings etc.

Self-protection

This protection is applied during production by coating the upper surface with slate chips (e.g. slated DERMABIT 43170) or copper or aluminium covering(e.g. MANTOLAMINA Al, MANTOLAMINA Cu).

The latter is recommended for non-treadable coverings and/or coverings with particular architectural structure (domes, complex shapes etc.) and gives avery attractive finish.


21/102

The following are the most frequently used coverings:- Non-insulated, non ventilated coverings- Non-insulated, ventilated coverings- Insulated, non ventilated coverings

- Insulated, ventilated coverings- Hot roofing- Inverted roofing

5.1) CRITERIA FOR IDENTIFYING APPROPRIATE SOLUTIONSCorrectly designing a covering system means taking into account all the parameters that affect the system as a whole.The "appropriate" solutions are givenbelow according to the geometry, access level and characteristics of the supporting element.

5.1.a) GeometryFlat roofing: this class includes horizontal coverings with slope of less than 5%Sloped roofing: this class includes coverings with slope between 5 and 50%

5.1.b) Access level

Non-treadable roofing: coverings to which access is allowed only for maintenance of machinery or the waterproofing membraneTreadable roofing: coverings for pedestrian traffic, designed for pedestrian traffic loads of 400 kg/sq.m.Roofing suitable for traffic: coverings for light (2t per axis) traffic"Green roof": coverings for roof gardens on which a layer of soil is laid

5.1.c) Characteristics of the supporting element

Floors in clay-cement/r.c.: floors cast in situ in reinforced clay-cement, floors cast in reinforced concrete etc.Pre-compressed reinforced concrete: prefabricated elements with metal reinforcement subjected to prior tensile stress.These elements have a high tensile strength.

Metal sheet plate: Galvanised corrugated sheet plate floors with different profiles.Wooden structures: trusses ,solid wood beams, planking, panelling etc.
