Abstract
A cover system is provided for waste sites and environmental closures, in which the cover system comprises a synthetic grass and an impermeable geomembrane that can be applied without the use of heavy earthwork equipment as temporary or final cover to control odors, erosion, gas migration and contaminate migration. The invention allows installation on very steep slopes and does not require the use of an extensive anchoring system to resist wind uplift or slope failure.
