DAMP PROOFING & RISING DAMP
Damp proofing describes the control methods used to prevent rising damp in walls of buildings. Given a basic understanding of cause and cure, rising damp can be prevented by professional or DIY damp proofing, whereby a remedial damp proof course is installed using damp proofing cream designed for the professional builder and those competent in DIY or by the insertion of an electro osmosis damp proof course.
Rising damp is a form of dampness caused by the movement of ground water through a permeable masonry wall having no effective damp proof course by which to stop damp from rising. The water rises through the pores in the masonry via a process called capillarity.
Suitable chemical damp proofing cream treatments are tested and approved in the UK for injection into the mortar bed course. The mortar presents the only continuous passage ascending up a wall through which water is able to rise. Therefore a mortar bed joint is the only layer that can function as a damp proofing layer. Introducing a chemical DPC into just each brick or block unit along a stretch of wall will not stop dampness rising through the joints between.
