Self-Adhesive HDPE Membrane Sheet. Which is used for waterproofing as geo-membrane. This Hot Melt Coating machine produces the HDPE self-adhesive waterproofing membrane and consists of HDPE film as basic material, polymer adhesive layer and protection layer (PE film or mineral particle, sand). It is specially designed to underground construction and use tunneling techniques, taking advantage of the strong bonding ability with post-pour concrete. The combination of special non-asphaltic adhesives and polymer sheets makes this material an advantage such as high tensile strength, impact resistance, Anti-corrosion, self-adhesive and easy construction. Cold application, non-flame heat: Strong adhesive ensures excellent adhesion, so no need for hot air welding is necessary. Antimicrobial and mold resistance: This product is theoretically, 100 years of underground use. Safe & environmentally friendly: The floor surface does not need special treatment, the construction process does not require solvents, no fuel in any form and does not require hot air welding. Scope of application: Under ground Parking, Tunnel, Railways, subways, highways, Underground projects, wastewater treatment plants and chemical tanks, Irrigation projects: reservoirs, dams, water channels and artificial lakes.
