Damp Proofing in construction is a type of moisture control applied to build walls and floors to prevent moisture from passing into the interior spaces. Dampness problems are among the most frequent problems encountered in residences.

If the damp is left untreated the issues become much worse, in some cases causing structural damage leading to significant repair costs with builders and surveyors. When left untreated, the unfortunate fact is that the damp invariably becomes more severe and will eventually cause structural damage leading to higher repair costs in the long run. When diagnosed promptly the underlying causes of the damp in your home can be addressed and treated both effectively and cost-effectively. When you first notice you’ve got a damp problem, that’s the right time to take action and call a damp proofing specialist.

Dampproofing is a coating, usually asphalt-based, that is either sprayed on or hand applied to the outside of the wall. Though less frequently recommended in modern residential construction, it is still an acceptable form of treatment in many situations. The drawbacks include an inability to seal larger cracks or holes left by form ties and the potential for damage by coarse or careless backfill. But with proper surface drainage, correctly installed foundation drains at the footing, and the absence of hydrostatic pressure to drive water infiltration, dampproofing can supply adequate and long-lasting protection for many crawl spaces and basements.
