Fitting Damp Proof Membrane Floor

Two options are available when faced with a damp floor.

Fitting damp proof membrane floor. Damp proof membranes are routinely used during the construction of a concrete floor. Replace the damp floor. This is because damp rising up through concrete floors is a pretty common issue. A damp proofing concrete floor solution is particularly important.

They do however always require a separate floor covering on top and special attention needs to be paid to the floor wall junction detail. It suggests that the damp proof membrane may be above or below the concrete and continuous with the damp proof courses dpc in walls piers and so on. These days damp proof membranes are required in the construction of all new buildings to prevent rising damp. Damp proofing concrete floors above ground damp proofing for extensions.

Option 1 install a floor membrane. 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. When constructing an extension or a new build home it is important that damp proofing measures are taken during the initial construction phase itself. Fully isolate the dampness from the floor covering.

If the slab is in poor condition then the most comprehensive solution is often to replace it and install a new damp proof membrane below. The approved document suggests that a ground supported floor will meet these requirements if the ground is covered with dense concrete laid on a hardcore bed and a dpm is provided.
