How to install damp proof membrane on concrete floor.

When can a dpm be installed. You should use them to protect all final floor finishes. The easiest solution for damp proofing concrete floors is to install a plastic membrane. 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. 1200 gauge dpms should be used when a floor is direct to the ground. Starting at one side of the room unroll the membrane and cut to fit the room as one would a carpet. 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.

All types of floor coverings can be installed on top of a plastic membrane. Essentially this is a plastic mesh sheet specially formulated to ensure that moisture cannot penetrate. They do however always require a separate floor covering on top and special attention needs to be paid to the floor wall junction detail. 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.

It sits between the concrete and the underlay floor covering. 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. This barrier is intended to stop moisture passing from one to the other. Concrete s porous nature means that water from under your home can seep up through your concrete floor making it damp.
