Damp Proofing

What is damp?

There are many causes of damp. Most damp is caused by the ingress of moisture. Moisture ingress can be caused by leaking pipes, high water tables in the ground, water penetration from sprinklers, water seepage through window frames or water seepage through cracked walls. Damp can be detected by sight, smell & damp surveying equipment.

Why should damp be treated?

There is common belief that painting over damp resolves the damp problem. This is a MYTH. Finding the source of the damp & investigating the cause of the damp is CRITICAL. Treating damp without thorough investigation & proper diagnosis will only waste money. Trapped moisture in damp walls if not treated will divert into other areas making the damp problem bigger.

If not treated, Damp can be harmful to the structural integrity of buildings. There are various types of damp with different effects. Treatment for each type of damp therefore differs.
