Systems for Subgrade Walls/Floors

SWEPCO Waterproofing Systems are installed at the construction stage. The systems for walls are installed on the outside surface of the walls; these systems are not for use on the inside walls of existing buildings that are already leaking. The Waterproofing Systems for floors are installed on the concrete sub-floor and are then covered with a concrete wear surface.

Which SWEPCO Waterproofing System to select depends on whether the structure is subjected to hydrostatic pressure, and if so, the amount of hydrostatic pressure (hydrostatic head). There are dampproofing systems for structures with no exposure to hydrostatic pressure as well as reinforced waterproofing systems to protect against hydrostatic pressure up to 30 ft. (9.14m) of hydrostatic head. Generally, the greater the hydrostatic head, the more material (and the more layers) in the system.
