Damp Proof Membrane Concrete Slab

Damp proof membrane is used to protect buildings from moisture by creating a damp resistant barrier.

Damp proof membrane concrete slab.

In newbuild situations it may be necessary to install a damp proof membrane on top of a concrete slab to enable moisture sensitive floor finishes e g. Damp proofing of slabs on ground. Preparation is key with these coatings and the substrate must be sufficiently clean and dry. Which type of coating is chosen will depend on the intended use of the floor.

Essentially this is a plastic mesh sheet specially formulated to ensure that moisture cannot penetrate. All types of floor coverings can be installed on top of a plastic membrane. Mostly the damp proofing is installed below the surface of the slab. The damp proofing of slabs constructed on ground can be done either below or above the surface.

A dpm damp proof membrane is a plastic sheet membrane that sits between a concrete slab or screed and acts as a barrier to stop moisture and contaminants entering a property from the ground. In essence providing a moisture barrier or damp proof membrane for concrete slabs. In these situations it is better to use a cavity drainage system to manage any water ingress rather than a dpm. You should use them to protect all final floor finishes.

Underfloor heating pipes are put in place if necessary. Can also be used as a drop sheet or for temporary weather protection when required. Mostly plastic film of vapor retarders is employed below the slab surface as a damp proofing membrane. Like all of our reinforcing accessories it has been manufactured from the highest quality materials to ensure durability whilst maintaining cost effectiveness.

Damp proof membrane under concrete slab as the majority of basements and cellars are fully below ground they are prone to water ingress. A damp proof membrane is put down. 1200 gauge dpms should be used when a floor is direct to the ground. It sits between the concrete and the underlay floor covering.

Concrete is poured and left to cure for a minimum of three days. Most damp proof floor coatings are applied directly to the concrete floor surface using a brush or roller. The easiest solution for damp proofing concrete floors is to install a plastic membrane. Insulation is put down.

When can a dpm be installed. Wooden floors to be laid on top of the slab enabling works to be completed more quickly than would otherwise be the case.
