Product overviewPure polyurea membrane, completely solvent-free, formulated for special waterproofing applications. Applied with hot spray equipment, it cures ultra-fast to form a continuous thermoset elastomeric membrane (capable of being both hard and flexible) with high mechanical and chemical resistance and long-term exterior durability. The membrane typically allows the system to be ready for service within hours.
Primary uses- Waterproofing systems requiring a barrier to radon gas, methane and similar harmful gases from the ground.
- Protection of tanks exposed to aggressive chemicals (chemical tanks, scrubbers, gas digesters).
- Waterproofing of foundations and structures to prevent gas ingress and to protect concrete against carbonation.
