The prefabricated modified polymer bitumen membrane consists of thermoplastic polyolefin stereoscopic polymers with high molecular weight and special distillation bitumen, with excellent anti-aging and phase reversal properties (type APP).
They integrate elements, self-integrating, to enhance the excellent quality of GRID BIT P + V VIADVEL membranes of flexibility, lightness, adhesion, aging and UV resistance. GRID BIT P + V VIADVEL is specially designed for use on bridges, viaducts, parking decks, rooftop gardens and for all applications requiring very high mechanical strength and excellent adhesion with matter. background.
Dual reinforcement with heavy-duty non-woven single-fiber polyester and rotting-resistant fiberglass mesh, offering high mechanical properties and excellent dimensional stability and static and dynamic puncture resistance. The top of GRID BIT P + V VIADVEL is covered with a special talc (activated stone) layer. The underside of the film is covered with a non-woven polypropylene mesh.
