Final cover Final cover is a multilayered system of various materials which are primarily used to reduce the amount of storm water that will enter a landfill after closing. Proper final cover systems will also minimize the surface water on the liner system, resist erosion due to wind or runoff, control the migrations of landfill gases, and improve aesthetics.〔Sharma, Hari and Reddy, Krishna. 2004. Geoenvironmental Engineering: Site Remediation, Waste Containment, and Emerging Waste Management Technologies. John Wiley & Sons, Inc., Hoboken, New Jersey.〕 A final cover system can include a top soil layer composed of nutrient rich soil, a protective layer to reduce the effects of freeze/thaw, a drainage layer which moves storm water, a barrier layer, and a grading layer. == Cover integrity == For a final cover system consisting of a geomembrane, an analysis of the mechanical properties of the geomembrane should be conducted to ensure cover integrity is not jeopardized by localized subsidence, bending, and cover slope stability.
