Review on Damp Proofing Cream

You should choose a chemical DPC system that is specifically designed to be introduced into the
mortar joints. 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
layer. Introducing a DPC into just each brick or block unit along a stretch of wall
will not stop the water rising through the joints between. In accordance with BS6576:2005 a
DPC should be sited at least 150mm above external ground level and internally beneath ground
floor joists, or close to the floor if solid. If the two are incompatible please phone our help line for
DIY or trade advice. Where a newly injected damp proof course is to finish additional injection
holes should be drilled vertically, up to a height of 1m in a zigzag pattern that follows the mortar
line, and the holes injected with DPC cream to form a vertical damp proof course that will stop
the transmission of damp from abutting walls.
