Damp Proof Course

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 walls.

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.

Therefore, some 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 or electro-osmosis damp proof course.

Chemical Damp Proof Course Injection

Damp Proofing London South 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.

Price Of Damp Proof Course in London

The price of chemical damp proof course injection in London is in the range of £35 to £55 per linear metre.

Damp Proofing London South will give you a price for your damp proof course injection. The price depends on the size of the area to be treated and whether it is a solid or cavity wall.
