Damp proofing explained
A damp proof course (DPC) is an
important part of the building process as it prevents rising damp. A damp proof course is designed
to stop the dampness at low level before it causes any problems higher up the
Often an old damp
proof course fails. If it does or there isn't one, a new DPC injection can be
done as a remedial measure. Usually a damp proof course (DPC) is installed
during construction of the building.
Damp Proof Course Systems
Damp proof course
(DPC) was first introduced and made compulsory for new buildings in 1875 by the
Public Health Act. It was made up of impenetrable bricks or slates back then.
older buildings have no damp proof course at all. Some of them have impervious
bricks, slates or bitumen which was used as the damp proof course.
In the new build
process the damp proof course is a membrane. It is placed into a mortar course
at the base of the walls.
If old DPC fails or
there isn't one, a new damp proof course can be installed as a remedial
treatment. Usually one of the following methods would be used: chemical damp
proof course injection, physical damp proof course.
Chemical Damp Proof Course Injection
Humberside Damp Proofing favours the chemical damp proof course injection. It involves
drilling a series of holes 150mm above the external ground level, 120mm apart,
along the base of the walls, preferably in the mortar, and injecting a silicone
gel or cream. The silicone ingredient in these products is designed to stop
dampness rising up the wall.
