DualProof is a fully and permanently bonded, self-adhesive, composite sheet that does not only waterproof but protects against gases and chemicals.
It consists of a sealed two layer highly flexible PVC membrane laminated with a non-woven PP-fleece. DualProof is cold/pre-applied, and is installed without heat or open-flame. It is applied to the blinding layer before the steel reinforcement is fixed and the concrete poured. The new PP FiberTex Technology gives the DualProof its unique bond and connection to the concrete. DualProof is an innovative system that prevents any lateral water migration between the waterproofing membrane and the structural concrete.
Areas of use
DualProof can be applied horizontally as well as vertically and is used in all applications where structures require protection against groundwater and seepage. Typically used in the following constructions:
- New build basements
- Foundations
- Tunnels
- Garages
- All other concrete constructions below ground.
Advantages of DualProof
- Waterproof, damp proof, gas proof and gives concrete protection against chemicals.
