WHAT IS TORCH ON WATERPROOFING?
Torch on waterproofing is a plastomeric modified bitumen waterproofing membrane, industrially manufactured by impregnation of the nonwoven spunbond polyester reinforcement with the waterproofing compound based on distilled bitumen modified with polyolefin polymers, which gives to the compound excellent technical characteristics.
Shaping of sheets, straightness, dimensional and surface uniformity are accomplished by hot calendering of the mass at hot melt fluid state.
It is a self-protected membrane. The upper surface is coated with coloured slate chips and selvedge slate free at one side for easy welding overlap. The lower surface is coated with a thermo-fusibile polyolefin film.
FIELD OF APPLICATION
Torch on waterproofing is particularly suitable as top layer in multi-layer waterproofing systems, with compatible membranes, or underlayer of discontinuos roofing.
General roofing, foundations, on or under floors or ground slabs, wall constructions, under tiles, are valid examples of the design application of this product. It is not suitable for roof gardens. It can be applied onto every substrate (concrete, masonry, steel, wood, insulation panel, membrane, etc.) and under heavy protection.
The excellent mechanical characteristics and thermo-dynamic stability make it suitable for any climate conditions and all the situations where a barrier against water is required.
METHOD OF APPLICATION
The excellent thermoplastic properties of the waterproofing compound allow the application with torch- on system or hot air generator. In particular situations, it could be applied with appropriate sealants or mechanical fastenings.
The application of the membrane must be carried in good weather conditions and after the substrate has been adequately cleaned and prepared.
Waterproofing of flat, sloping and pitched roofs, reinforced concrete, prefabricated concrete, masonry cement, metal and timber decks and terraces and for renovation purposes.
• Excellent stability to different temperatures, dual reinforced, excellent dimensional stability, rot proof, high strength.
