What is a damp-proof course?
The walls of houses generally have a barrier in them to stop rising damp from getting into walls. This is often a horizontal plastic or bitumen felt strip in the wall, 15cm above the ground level. Building regulations came into force in 1875, specifying that these had to be built into houses, so older houses may not have one.
What is a damp-proof membrane?
A damp-proof membrane (DPM) is a membrane material applied to prevent moisture transmission. A common example is polyethylene sheeting laid under a concrete slab to prevent the concrete from gaining moisture through capillary action. A DPM may be used for the DPC.
What is a chemical damp proof course?
A chemical damp course is installed by drilling holes at least 15 centimetres above the ground level fairly close together and feeding in a chemical compound that repels damp. Most houses that have had this done, you will be able to see the drill holes along the building on all exposed sides.
