Due to its level placement, high and low spots are eliminated, allowing improved water flow through the smooth interior surface of each lineal channel. Drainage is provided to both the exterior and interior sides of the foundation. Crossovers provide a connection between the inner and outer channels. Drain outlets allow water to exit the exterior channel through a drainage pipe, or the interior channel to a sump pit.
FORM-A-DRAIN also allows for a means of radon reduction. With simple adaptations, the same system, already in place, can perform as a radon reduction system. Lineals form a complete loop around the foundation, which is in conformance with the EPA’s “Model Standards & Techniques for Radon Control in New Residential Buildings.” Click on the "Installation" link at left to download our Installation Manual for complete details.
