CertainTeed New Construction Concrete
Footer Foundation Systems
Form A Drain is a patented,
all-in-one, stay in place, system that forms the foundation footing, provides
drainage and can be adapted to provide a sub-slab radon reduction system. In
addition to providing a superior footing, Form A Drain creates an ideal
drainage system, one that is parallel to the footing and below the foundation
wall. It also conforms with the EPA's "Model Standard & Techniques for
Radon Control in New Residential Buildings" and ASTME 14565-92 Standard Guide
for Radon Control Options for the design and construction of new low-rise
residential buildings
