How to install damp proof membrane on concrete floor.

Starting at one side of the room unroll the membrane and cut to fit the room as one would a carpet. A damp proof membrane dpm is used to create a barrier between a concrete or screed subfloor and the floor covering that is laid on top such as wood ceramic or quartz tiles laminate or carpet. Concrete s porous nature means that water from under your home can seep up through your concrete floor making it damp. When can a dpm be installed.

It sits between the concrete and the underlay floor covering. Installing a damp proof underlay for concrete floors.

These joints are then sealed with waterproof tape. All types of floor coverings can be installed on top of a plastic membrane. 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. Assuming that the damp proof membrane dpm under the concrete has failed in areas then yes you possibly would get the odd patch of dampness showing in the floor.

They do however always require a separate floor covering on top and special attention needs to be paid to the floor wall junction detail. You should use them to protect all final floor finishes. Physical damp proof membranes such as oldroyd xs slimline membrane are often quicker and easier to install than using damp proof coatings as they can be installed on still damp surfaces. If there was no dpm i would suggest a uniformal distribution across the whole floor.
