ABSTRACT:
A system for removing soil gases, including radon, and moisture from the proximity of building foundations is disclosed. In one embodiment, a network of grooves is scored in the top surface of a cement slab foundation. Tubing with filtered openings for the inlet of gases and moisture is buried in the groove network with the openings at the top surface of the slab. The tubing is connected to a vacuum pump which discharges gases and moisture. When an impervious floor covering is placed on top of the cement slab, the vacuum system prevents blistering or bubbling and other failure of the flooring from accumulations of gases and moisture under it.
In another embodiment, an array of tubes connected to the vacuum system passes through basement walls and is buried in the soil in proximity to a building foundation. Fluid collectors are provided at the ends of the buried tubes for gases and moisture diffusing into the collectors from the soil.
