ABSTRACT:
A permanent form-drain network adapted for radon remediation. A permanently installed form-drain system is partially piecewise modified and adapted to collect and remove radon gas from sub-slab, as well as basement and similar near-subterranean, portions of building. The partial piecewise modification of an existing form-drain includes adapting existing connector elements of the form-drain with vent tubes and differently molded pieces such as offset transition conduits and "T" shaped divergent conduits. The method for installing the invention conceives of the use of a radon accretion zone gas barrier made of an impermeable membrane.
