Is a damp proof membrane necessary? A damp-proof membrane is required when using certain insulation materials – such as mineral wool, cellulose, etc. – to prevent damp from working its way into the insulation. Where insulation is concerned, fitting a damp-proof membrane is important, as it safeguards the insulating properties of the material.

What is the difference between a damp proof course and damp proof membrane? Damp proofing is accomplished several ways including: A damp-proof course (DPC)is a barrier through the structure designed to prevent moisture rising by capillary action such as through a phenomenon known as rising damp. A damp-proof membrane (DPM) is a membrane material applied to prevent moisture transmission.
What do you use damp proof membrane for? A damp proof membrane (DPM) is a type of membrane material is used to prevent dampness from occurring through capillary action.

Why is water seeping up through my concrete?
When it rains, water is absorbed into the ground until the earth is too saturated to soak up any more water. At this point, the water will begin to rise to the surface, causing hydrostatic pressure to build up against your foundation and basement floors, which leads directly to water seepage into your home.
