Waterproofing vs Damproofing

Applied Technologies' waterproofing products offer many advantages over dampproofing. For decades foundations were only dampproofed, which only stops water vapor. Water under hydrostatic pressure can still push its way though a dampproofed foundation. Also, dampproofing is brittle and cannot bridge cracks in a foundation.

Many people call this "waterproofing", but it is not.

On the left: Damproofing is unable to bridge over cracks that develop in the foundation, letting water into the basement.


On the right: Applied Technologies foundation waterproofing membranes have rubber polymers that allow the waterproofing to span cracks in a foundation, thus preventing water from entering a basement.

To stop water from entering a foundation, waterproofing needs to be seamless, stretch over cracks and withstand water under hydrostatic pressure caused by heavy rains. Spray applied polymer-modified asphalt exterior foundation waterproofing stops water on the outside, before it can get into a basement.

J-Cote Waterproofing Membrane, J-Cote Waterproofing System, Hydra-Guard Waterproofing Membrane, and the Hydra-Guard Waterproofing System are ICC-ES evaluated foundation waterproofing materials that meet these criteria.
