Damp coursing

Damp-proof coursing (DPC) is a process that provides a protective barrier preventing moisture from passing through the walls of buildings. Moisture causes damage to internal decorations, condensation, fungus growth, mould, and a musty smell in your home. It is important to establish the type of mould present to ensure maximum protection against any further or lasting damage.

Tanking treatments

This involves coating or sealing walls of building structures below the ground to protect the internal surfaces from water penetration. This can be achieved by either a conventional tanking render system, or alternatively a tanking membrane system. Tanking treatments prevent any water ingress, effectively making the walls permanently watertight.

Waterproof RENDER Systems

Waterproof render is usually applied in conjunction with a damp coursing injection to internal walls to ensure no further damp penetration is experienced after treatments. This is usually applied with two coats of good quality waterproofing additive finished with a coat of plaster for decorative purposes.

Dry and/or wet rot can affect buildings old and new, and if any decay is discovered it must be identified and dealt with immediately. City Dampcoursing offer effective treatments to both identify the cause – and eradicate the problem.


Woodworm feed on the cellulose within timbers of building structures which can become particularly vulnerable when damp. This can cause significant damage unless treated. We offer a reliable solution and provide a suitable course of treatment to get rid of the problem.
