Damp Proof Membrane Concrete Slab

Typically a dpm is a polyethylene sheet laid under a concrete slab to prevent the concrete from gaining moisture through capillary action. Damp proof membrane under concrete slab as the majority of basements and cellars are fully below ground they are prone to water ingress. Mostly the damp proofing is installed below the surface of the slab.

It sits between the concrete and the underlay floor covering.

Concrete is poured and left to cure for a minimum of three days. Can also be used as a drop sheet or for temporary weather protection when required. Underfloor heating pipes are put in place if necessary. 1200 gauge dpms should be used when a floor is direct to the ground.

Essentially this is a plastic mesh sheet specially formulated to ensure that moisture cannot penetrate. In these situations it is better to use a cavity drainage system to manage any water ingress rather than a dpm.

Most damp proof floor coatings are applied directly to the concrete floor surface using a brush or roller.
