GeoVent - Gas Venting System

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.

Used in conjunction with Liquid Boot® or CoreFlex™ gas vapor barrier systems, GeoVent™ can alleviate the accumulation of gas vapors under the slab.

GeoVent™ is designed for use as active or passive under-slab venting when used with all CETCO gas vapor mitigation systems.

• Installed directly on subgrade eliminating costly trenching and potential interference or damage to existing underground utilities.
• Placed in closer proximity to the gas vapor barrier allowing for more effective venting of any accumulated gas vapor.
• Greater opening area per linear 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.
