Chemical Injection DPC

Where the problem has been identified as rising damp, and where a damp proof course is absent or inadequate, we offer different methods of retrofitting one; Chemical DPC and Electro Osmosis DPC.

Chemical Injection DPC

The installation of a chemical injection damp proof course is designed to create a continuous chemical barrier throughout the length and width of the wall to reduce the capillary rise of water up the wall. This is usually carried out by pressure injection, using high pressure and low pressure techniques, using an aqueous based fluid. A series of holes are drilled into the joints to a pattern determined by the thickness and construction of the wall. Then the chemical is injected into the wall creating a continuous barrier.

Chemical injection DPC is usually used for brick or block buildings; though our experienced surveyors will recommend the most suitable remedial action, and provide a detailed written survey and quotation.  Our trained surveyors will also identify any timbers which have been affected by dry rot or wet rot, as a result of the exposure to the damp conditions.  We may provide an insurance backed guarantee for all remedial damp works carried out.

Occasionally, it may be preferable to use the Newlath damp proof membrane system.
