IMPAC® PRO Poliéster APP

IMPAC® PRO POLIÉSTER APP is a prefabricated waterproofing system made from non-oxidized asphalt modified with propylene homopolymers and copolymers (APP). It is reinforced with a central layer of nonwoven polyester fabric made of continuous filament yarn (180 g/m²) combined with fiberglass filaments, manufactured using a laminated Spunbond process. The membrane features a colored mineral granule finish on the surface and a polyethylene film on the underside, which fuses with the asphalt through torch-applied thermo-fusion, adhering to the prepared substrate to form a unique waterproofing system that provides superior protection against moisture.
