A metal damp proof course (DPC) between the stone foundation and brick wall. Damp proofing in construction is a type of moisture control applied to building walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences.
An interior vapor retarder is useful in heating-dominated climates while an exterior vapor retarder is useful in cooling-dominated climates. In most climates it is often better to have a vapor-open building assembly, meaning that walls and roofs should be designed to dry: [ 6 ] either to the inside, the outside, or both, so the ventilation of ...
An example of a damp proof course of slate in a brick wall intended to prevent rising damp. A physical damp proof course made from plastic can be installed into an existing building by cutting into short sections of the mortar course, and installing short sections of the damp proof course material.
Masonry walls are built with a damp-proof course to prevent rising damp, and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an additive to the concrete.
Sometimes fine sand is used to backfill but more often insulation boards are laid against it before backfilling, particularly in an inhabited room. As a further precaution against water ingress, it is recommended that land drains be installed behind the protected wall at its base to prevent the buildup of hydrostatic pressure in wet weather.
