The cover system for waste containment facilities is designed to minimize infiltration and erosion and control egress of decomposition gases from municipal solid waste. The cover system must have an erosion control layer underlain by an infiltration control layer.

Integrated with geomembrane protection PRS-Neoweb™ geocells create impermeable, durable impoundment berms for waste containment and treatment. PRS-Neoweb slope protection is used to maximize the capacity of modern municipal solid waste landfills, by allowing significantly steeper and higher covers. This includes the protection and stabilization of steep slope surfaces and reinforcement of subbase of bottom liners.

PRS-Neoweb creates a soil stabilization system that holds the infill material in place and prevents mass movements by providing tensile reinforcement. PRS-Neoweb also improve the structural and functional behavior of soil infill materials. Filled with concrete, PRS-Neoweb is an environmentally safe and non-corrosive solution for mining waste, chemicals, slurry and sludge.
