No Open Flame Self-adhesive Polymer Waterproofing Membrane

Product Description

Double‑sided self‑adhesive polymer modified bitumen waterproofing membrane is based on SBS modified bitumen, covered with release protective films on both sides, featuring self‑adhesion on two surfaces. Both sides of the membrane can be bonded. It is mostly applied in composite waterproofing systems. The lower surface adheres to the substrate, while the upper surface can form tight bonding with the second waterproof layer or protective layer. It shall not be used for exposed applications in general.

Product Features

• Double‑sided self‑adhesion: High‑viscosity bitumen adhesive layers on both sides. Cold application without open‑flame torch melting, safe construction with no fire hazard.
• Self‑healing performance: The adhesive layer can self‑seal against punctures and hard object penetration to reduce water leakage risks.
• High elongation: Accommodates minor cracking and deformation of substrates with strong resistance to base displacement.
• Wide bonding compatibility: Bonds well with concrete, cement mortar, metal, wood and other substrates. Lap joints achieve self‑adhesive bonding for excellent seam tightness.
• Eco‑friendly & safe: No open flame and no solvent fumes, suitable for construction in fire‑ and explosion‑prone areas.
• Dual composite waterproofing: Serves as an intermediate transition waterproof layer to realize integrated composite of “substrate‑membrane‑upper waterproof layer” and minimize water channeling risks.

Scope of Application

Suitable for non‑exposed waterproofing of basement slabs, side walls, roof slabs and roofs of industrial and civil buildings; water tanks, reservoirs, metro tunnels and municipal projects; oil depots, chemical plants and other sites where open‑flame operation is prohibited; renovation of new and old buildings, and intermediate layers for composite waterproofing systems.
