ABSTRACT:
A radon mitigation method and system for mitigating the migration of radon into a building structure which includes an in-ground collection basin (200) formed in the foundation of the building structure. A liner (300) is located within the basin (200) with the liner (300) having both a sub-basin portion (320) and a rim portion (310). The rim portion (310) of the liner (300) forms a plenum chamber (400) between the liner (300) and the basin (200). The liner rim portion (310) is sealed to the basin (200) by a seal (410). A conduit (417) leads out of the building structure to remove gas from the plenum chamber (400). A pump (13) is operatively connected to the conduit (417) to exhaust gas through the conduit (17) to remove any radon within the plenum chamber (400) to the outside of the building structure.
