QingShan self-adhesive rubberized asphalt waterproofing membrane is a flexible waterproofing system combining SBS elastomeric modified bitumen and PE film or aluminum foil on the upper surface, or no film covered but self-adhesive on both sides. The outer surface is coated by removable silicon-coated film or silicon-coated buckle paper as anti-sticking isolation material.  Self-adhesive membrane polyethylene film on the upper surface can be applied to non-exposed roof of all kinds of architecture, subterranean and indoor project.It can be applied to the waterproof project of engineering such as open-cut subway, tunnel, pool, and aqueduct. It is especially applicable to the engineering whose construction is prohibited to use naked fire.Self-adhesive membrane aluminum foil on the upper surface can be applied to waterproof project of exposed structure of all kinds of architecture. Self-adhesive membrane on two sides can be applied not only to assistant waterproof engineering, but also to the adhesion and airtightness of the layer joint between two incompatible materials
