Method and system for radon mitigation
First Claim
1. A method mitigating the migration of radon into a building structure having an in-ground collection basin formed in the foundation thereof and ground moisture drain conduits leading into said collection basin comprising the steps of:
- (a) establishing in said basin a shoulder portion;
(b) establishing a liner member formed substantially of a gas impermeable material, said liner member having a sub-basin portion extending longitudinally from a laterally extended rim portion, said sub-basin portion having a predetermined dimensional configuration;
(c) placing said liner member within said basin, said liner member rim portion engaging said basin shoulder portion;
(d) establishing a plenum chamber between said basin and said liner member by forming a substantially airtight seal at said engagement of said liner member rim portion and said basin shoulder portion, said plenum chamber receiving the discharge from said ground moisture drain conduit;
(e) establishing a gas exhaust conduit extending out of said building structure from said plenum chamber; and
,(f) generating an exhaust airflow from said plenum chamber through said gas exhaust conduit, whereby radon entering said plenum chamber is expelled out of said building structure.

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.

7. A radon mitigation system for mitigating the migration of radon into a building structure having an in-ground collection basin formed in the foundation thereof and a ground moisture drainage conduit leading into said collection basin comprising:
-
(a) a liner member formed substantially of a gas impermeable material disposed within said basin, said liner member having a longitudinally-extending sub-basin portion and a rim portion extending substantially radially outward therefrom, said rim portion contiguously engaging said basin to define a plenum chamber between said liner member and said basin, said sub-basin portion having a predetermined dimensional configuration; (b) means for sealing said engagement of said liner member rim portion and said basin in substantially airtight manner; (c) a gas exhaust conduit coupled to said liner member and leading out of said building structure for the expulsion therethrough of gas from said plenum chamber; and
,(d) means operably coupled to said gas exhaust conduit for generating an exhaust airflow through said gas exhaust conduit from said plenum chamber, whereby radon entering said plenum chamber is expelled out of said building structure. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A radon mitigation system for mitigating the migration of radon into a building structure comprising:
-
(a) a basin member extending through the foundation of said building structure, said basin member having an upper basin portion connected to a lower basin portion by a shoulder portion, said upper basin portion extending sufficiently through said foundation to receive the conduits of said building structure leading from said above-ground drains thereof, said lower basin portion receiving the ground moisture drain conduits of said building structure; (b) a liner member formed substantially of a gas impermeable material disposed within said basin member, said liner member having a longitudinally-extending sub-basin portion and a rim portion extending substantially radially outward therefrom, said rim portion contiguously engaging said shoulder portion of said basin member to define a plenum chamber between said liner member and said lower basin portion of said basin member, said sub-basin portion being adapted to receive therein at least a portion of a predetermined sump pump assembly; (c) means for sealing said engagement of said liner member rim portion and said basin member shoulder portion in substantially airtight manner; and
,(d) means coupled to said liner member for guiding and expelling gas from said plenum chamber and out of said building structure. - View Dependent Claims (15, 16, 17, 18, 19, 20)
