Exposed Vent Detail

In certain circumstances gases can accumulate under a geomembrane and cause uplift. A gas venting system can prevent damage to the liner when uplift is predicted. A geo-net or geotextile vent layer is provided under the liner and up the slopes. At the top of the slopes a vent is provided to allow the gas to escape to atmosphere. The detail in this drawing shows a typical gas vent at the top of a slope in an exposed geomembrane. A drawing for a backfilled geomembrane vent is also available.
