  • Waterproofing

    Waterproofing is the combination of materials or systems that prevents water intrusion into structural elements of a building or its finished spaces. Waterproofing membranes consist of waterproof plastic, rubber, or coated-fabric materials. These materials, when properly installed, are used in a system to prevent the ingress of water into foundations, roofs, walls, basements, buildings, and structures.

  • Above-Grade Vs. Below-Grade

    Most above-grade materials are breathable in that they allow for negative vapor transmission. This is similar to human skin; it is waterproof, allowing you to swim and bathe but also to perspire, which is negative moisture transmission. Most below-grade materials will not allow negative transmission and, if present, can cause the material to blister or become unbonded. Below-grade products are neither ultraviolet-resistant nor capable of withstanding thermal movement experienced in above grade structures, Whereas below-grade materials are not subject to wear, above-grade materials can be exposed to wear such as foot traffic. Below-grade products withstand hydrostatic pressure, whereas above-grade materials do not.
