The Difference between Damp-Proofing & Waterproofing

at | Category: Uncategorized

Damp-proofing is a low-cost method of retarding water infiltration and should by no means be confused with actual waterproofing. Often people will use those terms interchangeably and mistakenly assume that they mean the same thing.

Damp-proofing will not protect a basement and house foundation from flooding. Instead it acts as a complementary method to waterproofing. It helps prolong the effectiveness of a waterproofing job by retarding water inflation and strengthening the waterproof membrane.

Damp-proofing involves the spraying of liquid asphalt or tar based compounds into the foundations of a wall. The asphalt based products are designed to block water vapor transmission and that is basically the extent of their capability. Damp-proofing compounds generally become brittle after they dry and if cracks develop in your walls, they are unable to bridge these gaps.

To permanently stop water and water vapor from entering your foundation walls, you need to waterproof them. Waterproofing will prevent flooding from occurring and will bridge foundation cracks when they start to occur. Unlike the brittle tar-based compounds, waterproofing materials retain their elasticity and some variants of waterproofing actually have self-sealing properties.
