Use this 3 part SimpleSpecs™ master specification to specify bituminous waterproofing in sheet form on below-grade walls and decks.

Waterproofing is a “peel-and-stick” product applied to solid surfaces, including concrete and masonry on below-grade walls and plaza decks. This type of waterproofing must be covered by soil or other construction. Bituminous sheet waterproofing comes in roll form with a release paper and is self-adhering.

Waterproofing is inherently self-sealing, so small punctures and fastener holes do not require special treatment. The material is 36 inches wide and requires numerous lap joints, which can be the weakest part of the system.

This waterproofing requires a protection course to prevent damage during backfilling and placement of overlying construction. A drainage course applied over the waterproofing reduces hydrostatic pressure, thereby reducing the possibility of leaks. Some drainage boards can also act as a protection course.
