ABSTRACT:
A gas capping liner system is described which encompasses a top channeled component and a bottom perforated layer component. The top channeled component has a plurality of alternating longitudinally extending channels. The channels are of two types, (1) structural for supporting the weight of overburden clay and topsoil above the liner and (2) gas-receiving, which permit the landfill gas to be collected. The perforated layer component is positioned such that the perforations are located above the gas-receiving channels.
