1 Waterproofing easy to lay dimensionally stable waterproof resistant PATENT PENDING

2 New-generation of waterproofing METHOD FOR LAYING is laid dry on both wooden and cement supports. Laying is easy and fast: simply overlap the sheets by at least 5 cm using the apposite joining tabs, and finally fix them using the two-way butyl sealant, supplied as an accessory. Waterproofing foundation: A. Position the sheets directly onto the foundation B. Lay the electrowelded net C. Apply the finishing cement layer

3 METHOD OF LAYING For all applications refer to the following recommendations: 1. Prepare surfaces: removing plaster (1-2 cm) from walls where necessary, up to about 15 cm from the floor; cleaning horizontal and vertical surfaces from dust and from eventual residual rubble. 2. Fix on the vertical wall using silicone (fig. A) or small nails, than unroll the sheet on the surface to be coated. For a proper adhesion to the wall the use of a roller (fig. B) is recommended. A. B. 3. Repeat the process for the adjoining layers, overlapping the edges and blocking them with the butyl sealant (fig. C). Use again the roller to press the sealant (fig. D). C. D.

4 Critical points: Concave corners Shape the sheet folding it in proximity of the corner, so that it can adhere to vertical walls (Fig. A and B). Fasten the folded sheet, using for example normal stapler clips (Fig. C), and than fix it onto the walls with silicone. A. B. C. Convex corners Shape the sheet forming flaps and make them adhere to vertical walls (Fig. A, B and C). Fix the sheet onto the vertical walls using silicone (Fig. D, E) and make sure that the base of the corner is properly sealed (fig. F). A. B. C. D. 3. Cut a piece of to cover the bare corner, overlapping it to the sheet already fixed on walls and floor (Fig. G, H). Finally fix the angular element with a further application of silicone. E. F. G. H.

5 Applications characteristics INTRODUCTION The history and development of buildings is directly related to man s need to protect himself from water. Water penetration can be caused directly by rainwater or conversely by water permeating through the soil from the groundwater table. Since ancient times, man has tried to remedy this problem, for example by using clay and lime, or coal tar pitch as a sealant between structural stone elements. With the onset of the industrial era, great evolution has taken place, both in building methods as well as materials technology. Progress has been relentless and increasingly fast, pushed by research and industrial production. In the long run, buildings designed with insufficient waterproofing systems, especially in respect of roofs and foundations, may experience serious problems in terms of stability. has developed the ideal product to permanently solve the problem of infiltrations for pitched roofs, green roofs, underground garages, foundations, and where surfaces have been converted into a garden, terrace or balcony. is a material produced using a reinforced polyester nonwoven that combines full waterproofing integrity, together with important characteristics such as material stability and resistance, through the polyolefinic film integrated within the two nonwoven layers. BUILDINGS WITH PITCHED ROOFS The roof of a building is the area which is most subject to the aggressivity of weather elements. The primary objective of the more exposed sections of the roof (roofing tiles and shingles) is to prevent water from being retained and, due to the pitch of the roof, facilitate the flow of the water into the gutters for permanent disposal. Unfortunately over time, the risk of water infiltration through the roof is high, due to the movement or breakage of the covering tiles or shingles. Providing a secure roofing system is essential and to this purpose the design phase must be extremely accurate. One excellent solution is the installation of. An extremely effective waterproofing and vapour control barrier that can be fitted directly on to wooden battens, wooden planking, clay blocks, fixed by the laths containing thermal insulation. An efficient roofing design must take into consideration construction criteria as follows Air or: Wooden planking or clay block floor slab ECOZERO thermal insulation between the laths Counter laths B-PAR breathable underslating Laths and counter-roof laths Roofing tiles 7 2 1

6 Applications characteristics UNDERGROUND GARAGES AND FLAT ROOFS Breathable The need to optimize living spaces has led to a sharp increase in the design and construction of areas below the land surface together with the need to restore the surface, possibly with green. In parallel, modern building techniques have been moving towards more innovative solutions for the construction of buildings with flat roofs, in order to make the roofing space fully enjoyable, possibly for use as a garden or sunroof. The most common problems associated with such structures have traditionally been the infiltration and the draining of rainwater. In both respects is a valid alternative to traditional waterproofing methods. Applied directly onto the flat roofing, it guarantees excellent waterproofing protection and adjusts easily to any surface Breathable 2 1. Load-bearing clay block 2. waterproofing 3. Draining gravel layer 4. DRENOTEX drainage and anti-contaminant geotextile 5. Grass surface TERRACES AND BALCONIES Very often the external surfaces of terraces or balconies are covered with unsightly humidity stains, cracks, or large areas where the plaster has fallen off, sometimes revealing the metal reinforcement. The cause? Poor waterproofing protection. is recommended for the repair of both new flooring, and areas to be renovated, as it offers full waterproofing protection as well as the flexibility required for areas of flooring. can be laid directly on to an untreated surface as part of the foundation, in preparation for the new floor. In the case of renovation, can be laid directly onto the old flooring prior to the application of a suitable adhesive for the new tiles, thus avoiding expensive time and resource to remove the old flooring system.

7 Applications characteristics FOUNDATIONS The formation of the building foundation is more complex, compared to construction of an exterior wall above ground, where the retaining materials are more likely to dry naturally in the atmosphere, and thus limit the risk of water infiltration. Construction of such a wall underground however means that the materials are continually in contact with the soil, which is very often wet or damp. Due to the porosity of most building materials, water is able to rise through the brickwork through capillarity, unless a suitable waterproof system or membrane is utilised to offer protection. The use of, placed directly on the concrete bed and over plinthes, will provide total protection from water and humidity.

8 Accessories BUTYL SEALANT For the ideal joining of sheets, Freudenberg Politex recommends a two-way strip of extruded sealant in black synthetic rubber, supplied as an accessory. Applications To join sheets of waterproofing membranes For specific roofing applications Advantages Excellent adhesive Suitable for all applications Extremely flexible Good resistance to UV rays Easy to use with no waste of material Included in Category A sealants (as defined by NFRC Technical Bulletin 36) Operating temperature -40 C and +90 C TECHNICAL CHARACTERISTICS U.o.M. Dynamic share adhesion N/cm Peel adhesion Force to compress by 20% Specific gravity N/cm N/cm 2 g/cm ,5 Supply In rolls, on silicone paper. Warning To obtain the best results in joining, the laying surfaces must be clean, dry and free from oil and grease. Lay the nonwoven onto the surface, apply the sealant, remove the paper from the back of the sealing strip and bring the other surface in contact. Rolls of butyl sealant must be stored in a horizontal position and in their original packaging. They must be kept away from sunlight, in a cool dry place, temperature range between 5 and 25 C. Under these conditions, the product can be stored for up to a maximum of two years.
