Embodiment Construction

[0030] The present invention provides a covering or closure system for various types of waste deposits. As mentioned above, these waste sites can include earth mounds, landfills, phosphogypsum stockpiles, heap leach pads, mining waste, soil stacks, and the like.

[0031] In the present invention, artificial grass is used in combination with an anti-seepage geomembrane to provide a new and useful covering system. This combination (sometimes called a composite material) can be used for both slopes and tops of waste yards.

[0032] The cover system of the present invention represents an innovative and economical approach for hazardous waste and solid waste landfills and other environmental enclosures. These facilities typically require closure with a final cover consisting of layers of soil and geosynthetics. The purpose of the cover system of the present invention is to prevent exposure of waste to the environment, increase collection of landfill gas, and minimize infiltration...

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.

Description

[0001] This application is a continuation-in-part of U.S. Patent Application Serial No. 11 / 900,831, filed September 13, 2007, which in turn claims the benefit of U.S. Provisional Patent Application Serial No. 60 / 844,576, filed September 14, 2006 rights and interests. technical field [0002] The present invention relates to covering systems for waste disposal sites and other environmental enclosures. In a more specific aspect, the present invention relates to a closed covering system for waste disposal sites and other environments, wherein the covering system comprises artificial grass and an impermeable geomembrane. In another more specific aspect, the invention relates to such a covering system comprising a drainage system comprising a synthetic drainage assembly. [0003] In this application, the following terms should be understood as having the assigned definitions: [0004] *Waste Sites— Refers to soil slopes and sites where waste accumulates, such as landfills, phosph...
