Below Grade Waterproofing
Below-Grade waterproofing is the construction practice of applying membranes and coatings to the foundation walls of the structure under street or ground level, as part of the building envelope. It can go by other names such as below-ground or basement waterproofing.
Effective waterproofing and water management techniques goes hand-in-hand to keeping the below grade areas leak free. An astute project owner would ask: What below grade waterproofing methods and processes should be used to ensure the quality and performance of the finished building(s)?
The goal of damp proofing is to prevent moisture fro passing through the concrete walls into the interior space of your basement or crawl space. Most modern homes have a damp–proof coating, which was installed to meet local building code requirements as the home was being constructed.
Elastomeric coating is an above-grade exterior wall or roof coating that is approximately 10 times thicker than paint. It forms an incredibly thick yet flexible coating that helps waterproof the exterior of a structure. Unlike other types of coatings or paints, it can bridge hairline cracks to complete an airtight waterproof seal. It is a suitable material for use on surfaces such as stucco, concrete, masonry and more. Elastomeric coatings can be used on walls as well as roofs. When the elastomeric coating is applied it is in liquid form, it completely dries, hardens and bonds to the structure and yet remains flexible, moving, bending and flexing as the structure underneath moves, bends and flexes. In addition to providing a waterproof protective coating to a structure, it also helps protect the structure from damage. Elastomeric coating is chemical and mildew. It can be tinted to a number of colors and retains its color very well long-term. For these reasons, it helps maintain the appealing look of the exterior of the building and wards off the less appealing look of damage, wear and tear.
