China Factory Direct Roofing Torched-on Bitumen Waterproofing Membrane

factory direct roofing torched-on bitumen waterproofing membraneProduction instruction
SBS(Styrene Butadiene Styrene) modified bitumen membrane is made by saturating the base in bitumen, or thermoplastic elastomer (such as styrene butadiene-SBS), reinforced with polyester or fiberglass, finishing the upward face with fine sands, mineral slates (or grains) or polythene membrane etc.

CharacteristicsGood waterproof performance; High tensile and tearing strength, elongation and size stability which accommodates substrate movement and deformation;Anti-corrosion, mildew resistant and weather resistant;Anti-puncture and rooting resistant, fatigue resistant;Hot melt construction, solid and long-lasting;SBS modified bitumen membrane is specially applied in the cold district, while APP modified bitumen membrane is more suitable for hot district with high temperature.

Application

Roof and underground in industrial and civil buildings; bridge, subway, tunnel, swimming pool, etc.Waste landfill, sewage plant, irrigation system, etc.
