Waterproofing vs. Dampproofing

  • Did you know that there is a significant difference between waterproofing and dampproofing? Dampproofing simply slows down water penetration, but will not completely waterproof your foundation. Dampproofing, however, does protect against water vapor transmission. For the value based homeowner, dampproofing is an alternative to waterproofing, usually done with an easy to spray-on membrane, which dries into a seamless coating. Mar-Flex’s DampFusion Water Based acrylic dampproofing membrane is an economical solution to many damp basement or foundation issues. Value priced for the everyday consumer.
