Waterproofing Membrane

In Plain English

A material applied to foundations and roofs to prevent water from getting into the building.

Definition

A waterproofing membrane is a material applied to below-grade walls, foundations, roofs, and wet areas to prevent water infiltration into the building structure. Common types include sheet-applied, fluid-applied, and crystalline waterproofing systems. The selection of waterproofing system depends on the substrate, hydrostatic pressure conditions, and accessibility for future maintenance.

Example

The below-grade parking garage required a fully adhered waterproofing membrane with 2 inches of protection board before soil backfill.
