In building construction, waterproofing is a fundamental aspect of creating a building envelope, which is a controlled environment.
Roofing materials are generally designed to be water-resistant and shed water from a sloping roof, but in some conditions, such as ice damming and on flat roofs, the roofing must be waterproof. Even the roof covering materials, siding, foundations, and all of the various penetrations through these surfaces need to be water-resistant and sometimes waterproof.
Many types of waterproof membrane systems are available, including felt paper or tar paper with asphalt or tar to make a built-up roof, other bituminous waterproofing, EPDM rubber, hypalon, polyvinyl chloride, liquid roofing, and more.
Walls are not subjected to standing water, and the water-resistant membranes used as housewraps are designed to be breathable to let moisture escape. Walls also have vapor barriers or air barriers.
Damp proofing is another aspect of waterproofing. Masonry walls are built with a damp-proof course to prevent rising damp, and the concrete in foundations needs to be damp-proofed or waterproofed with a liquid coating, basement waterproofing membrane (even under the concrete slab floor where polyethylene sheeting is commonly used), or an additive to the concrete.
A potential problem in earth sheltered dwelling is too much humidity, so waterproofing is critical. Water seepage can lead to mold growth causing significant damage and air quality issues. Properly waterproofing foundation walls is required to prevent deterioration and seepage.
