We use the most effective treatment available for Damp Proofing

The most effective way of treating damp is by chemical injection.

AD Damp proofing
only use chemicals that are BBA approved, the BBA (British Board of Agrément) rigorously test every creation.


Consequently we are able to offer a 30 year Insurance Backed Guarantee on the cream that we use for our chemical damp proof courses. The chemical level stops the liquid by climbing past it, therefore forming a waterproof barricade in the base of the structure/wall.

Re-plastering Even when a new damp proof course has been installed and the rising dampness controlled, the wall will still have water from the former dampness, together with salts passed up from the ground.

These will remain to attack plaster and decorations. Gypsum based plasters
will be transformed by the action of the salts so that they essentially entice liquid
from the air, and by no means dry out. It is consequently significant that the old
affected plaster is removed and replaced with a superior plaster which repels any
attacks by the salts. This is occasionally referred to as renovating plaster or
chemical rendering and can be purchased as a special plaster system or mixed
according to a particular specification.

If not stated, our quotations will automatically assume that existing plaster thickness is not more than 25 mm (1 inch). If when the plaster is removed and the thickness is found to surpass this, additional costs may occur for dubbing out coats of rendering which will be needed to bring the fresh plaster up to the level of the current plaster.

This may increase the cost of the work undertaken due to time, labour and materials involved. In the event of this occurring you will be made aware of this before any further work commences.
