GeoVent Sub-Slab Venting System
Venting systems are typically installed in conjunction with a vapor barrier when volatile or explosive gases are present. GEOVENT is a low-profile pressure relief, trenchless collection and venting system designed to improve venting efficiency and reduce installation costs. GEOVENT has several advantages over trenched installations and can be used as an “active” or “passive” venting system depending on the specific project. GEOVENT can alleviate the accumulation of gas vapors under the slab and is used for the removal of radon and other harmful volatile compounds.
GeoVent Advantages
-
Installed directly on subgrade eliminating costly trenching and potential interference or damage to existing underground utilities
-
Placed in closer proximity to the vapor barrier allowing for more effective venting of any accumulated vapor
-
Greater opening area per lineal foot of pipe and integral filter fabric allowing for higher ventilation efficiency
-
Installed at a higher elevation reducing susceptibility to inundation from perched groundwater that may accumulate beneath the building foundation
-
Flow characteristics meet or exceed that of a typical trenched installation. the overall capacity of the system is far in excess of typical gas flux rates
How it Works
GeoVent is a 3-dimensional vent core that is wrapped in a non-woven, needlepunched filter fabric and is used with GeoVent End Outlets, reducers, and pipework components to form part of a passive and active sub-slab venting system.
GeoVent can be installed directly onto the subgrade to eliminate trenching and potential interference or damage to existing underground utilities.
