e.vent is a composite low profile pressure relief and collection system designed to mitigate the buildup of methane gas and contaminated vapor under an overlying structure. e.vent is most commonly designed to operate passively, but may also be designed as an active system when conditions require. e.vent features a lightweight, three-dimensional, highly flexible polypropylene core and a non-woven geotextile filter fabric. The filter fabric is bonded to the polypropylene core to prevent fine substrates, such as sand, from clogging the vent pipe.


Cost effective alternative to traditional trenched PVC or ADS pipe systems

Placed directly below the barrier system to drastically reduce vapor accumulation under the structure

Can operate as a passive system with the ablity to activate in the future
