Our treatment, often referred to as ‘tanking‘ is sometimes carried out in association with other damp proofing works, which may have been recommended by our damp proofing surveyor so you can be sure you will have no further problems in the future. You will be issued with a detailed report on the extent of the damp together with our recommendations for the best method of treatment for your particular problem.

How Tapco HomeDry eliminates lateral damp penetration

Damp proofing walls below ground level is a very specialist proceedure which is carried out by our trained and experienced operatives who have many years of structural water proofing experience. We use a structural water proofing system which is alkali-resistant synthetically modified cement. This is mixed with styrene-butadiene and water, producing a water proof barrier system against both moisture and hydrostatic ground water. After only 24 hours our finished system is plastered by us in accordance with our damp proof plastering system, ready for decorating. All treatments are covered by our long term guarantee which can be protected by Guarantee Protection Insurance (GPI)

Whether the problem involves a small isolated area or a complete basement conversion ensure it is only carried out by a professional damp proofing company who are members of the Property Care Association (PCA) and Trust Mark (Government Endorsed Standards)
