DualProof External Pre-Applied Membrane 1.2m x25m

DualProof is a new, lightweight and easy to use external, pre applied, external waterproof membrane.

DualProof works with site poured concrete. DualProof is installed to the oversite and dressed up the slab shuttering before the rebar is laid and the concrete is poured.

DualProof can also be used to externally waterproof poured concrete retaining walls.

The unique spun non-woven polypropylene fully bonds to the outside of the new concrete to provide a permanent external waterproof barrier.

DualProof is often used to provide a secondary waterproofing system in addition to a Delta Cavity Drainage system.

DualProof is also used to externally waterproof concrete where an exposed internal concrete finish is required.

Lift pit waterproofing in new build projects is made easy using DualProof. The external waterproofing system means that the lift fixings points do not damage the waterproofing layer.


DualProof CEM Adhesive is used to permanently seal the joints between DualProof External Pre Applied Membrane. We recommend 3 Tubes of CEM Adhesive for every roll of DualProof.
