Selection, design and installation of damp-proof courses in both solid and cavity masonry constructions.

This British Standard contains recommendations for the selection, design and installation of damp-proof courses (DPCs) in both solid and cavity masonry constructions: it does not cover the waterproofing of underground structures, such as basements, where water is under hydrostatic pressure (see BS 8102). This standard does not deal with the installation of chemical DPCs (see BS 6576) nor with the control of condensation (see BS 5250) nor with the surface treatment of masonry with water repellents (see BS 6477).

Guidance on basic principles concerning DPCs, their function and their installation in masonry is given in clause 3.

NOTE The titles of publications referred to in this standard are listed on the inside back cover.
