ABSTRACT:
A system for forming a blocking layer of water-saturated soil surrounding the foundation of a building to be protected from ingress of radon gas or other soil gas contaminents. The system includes at least one set of parallel positive and negative electrodes positioned in the soil, adjacent and spaced from the foundation. Typically, the negative electrode will be positioned closest to the foundation. A low level voltage is applied to the electrodes from a DC power source. One or more sets of such electrodes will be positioned in the soil surrounding the foundation or at least that portion of the foundation most susceptible to gas ingress.
