A gas collection grid for use at landfills having a gas-producing waste pile, including a lower geocomposite positioned over the gas-producing waste pile, a protective layer of soil is positioned over the lower geocomposite. An upper geocomposite is positioned over the protective layer of soil such that the protective layer of soil is positioned between the lower and upper geocomposites. An impermeable geomembrane is positioned over the upper geocomposite. A cruciform gas collector conduit grid is positioned within or atop the protective layer of soil and has a plurality of collection orifices formed adjacent the vertical openings formed in the protective layer of soil. The impermeable geomembrane is non-perforated adjacent the collection orifices and the cruciform gas collector conduit grid is adapted for delivering collected gas laterally from beneath the geomembrane rather than vertically through the geomembrane.

A solar energy system for use with tufted geosynthetics on a substantially flat surface having a racking structure with bases and attachments for frictional seating to a tufted geosynthetic ground cover system, a bifacial solar panel mounted to the racking system and electrically connected to a connection box for communicating electrical current to an electricity power conditioner of an electrical current grid generated upon exposure of the solar panel to ambient light. A method of using a solar energy system with tufted geosynthetics cover system is disclosed.

Solar energy system for use with tufted geosynthetics

A solar energy system for use with tufted geosynthetics on sloping ground without the use of a traditional racking system. A frame attaches to the tufted geosynthetic cover to provide a flap and a solar panel secures to the flap directly or through a polymeric layer that attaches to the frame positioned between the flap and the tufted geosynthetic land cover with the solar panel adhesively attached to the polymeric layer. The solar panel being attached to the tufted geosynthetic land cover generates energy upon exposure to light. A method of securing a solar panel to a tufted geosynthetic land cover system for generation of energy is disclosed.

A system for covering various types of ground where water and wind erosion protection are needed comprises a composite of at least one geotextile tufted or knitted with synthetic yarns (forming a synthetic turf), an open grid mesh, and a geo-filter (filter fabric). The filter fabric is positioned in direct contact with the ground surface, the open grid mesh is positioned over the filter fabric, and the synthetic turf is positioned over the open grid mesh. The system provides a beneficial erosion protection that does not require maintenance and can be used to cover slopes without requiring vegetative support and/or a topsoil layer. An optional sand layer can be placed atop the synthetic turf as desired as infill to ballast the material and protect the system against wind uplift.

A gas vent for a landfill includes a sub-surface gas collection manifold for collecting sub-surface gas from beneath a geomembrane. Preferably, the collection manifold includes a plenum for receiving sub-surface gas. A conduit is connected to and extends upwardly from the plenum, with the conduit communicating with the interior volume of the plenum and having an upper discharge end. The conduit is adapted and provided for communicating sub-surface gas from within the interior volume of the plenum through the geomembrane. A low-pressure relief valve is operative for opening when positive pressure exists within the conduit. The low-pressure relief valve comprises a valve membrane normally resting upon a seat and which is lifted off the seat by low positive pressure.

A method for covering a site with synthetic turf includes laying down a first elongate strip of synthetic turf, laying down a second elongate strip of synthetic turf, with the second elongate strip of synthetic turf is laid down substantially adjacent to the first elongate strip of synthetic turf in a manner such that a portion of the second elongate strip partially overlays a portion of the first elongate strip forming a lap joint. The method also includes the step of applying heat and/or pressure to weld the first elongate strip of synthetic turf to the second elongate strip of synthetic turf along the lap joint.

A mechanically stabilized earth (MSE) wall and/or synthetic grass cover including alternating layers of granular fills and soil reinforcement geo-grids; a wire wall facing; and a synthetic grass cover for covering the wire wall facing, the synthetic grass comprising a geo-textile backing and a plurality of synthetic grass blades comprising synthetic yarns tufted into the geo-textile backing and having a length and density sufficient to substantially shade the geo-textile backing from solar UV rays.

Synthetic grass cover for MSE walls

A synthetic ground cover system for erosion control to be placed atop the ground, including a synthetic grass which comprises a composite of one or more geotextiles tufted with synthetic yarns and an impermeable backing/layer. The synthetic ground cover also includes a sand/soil infill ballast applied to the synthetic grass and a binding agent applied to the sand/soil infill to stabilize the sand/soil infill against high velocity water shear forces.

A near-surface collection manifold for extracting and/or venting sub-surface gas from beneath a geomembrane includes a plenum defining an enclosure with an upper portion. A conduit extends upwardly from the upper portion of the plenum, the conduit communicating with the interior volume of the plenum and has external threads for receiving a threaded nut thereon. The conduit is adapted and provided for extending through an aperture in the geomembrane for withdrawing sub-surface gas from within the interior volume of the plenum and through the geomembrane. A gasket having an opening formed therein is slipped over the conduit and above the geomembrane so that the geomembrane is sandwiched between the gasket and the upper portion of the plenum. A threaded nut is fitted to the conduit and above the gasket for securing the gasket against the geomembrane, thereby sealing the geomembrane to the upper portion of the plenum.

A passive valveless gas vent for a landfill includes a sub-surface gas collection manifold for collecting sub-surface gas from beneath a geomembrane. The collection manifold includes a plenum for receiving sub-surface gas, and the plenum defines an interior volume. A conduit is connected to and extends upwardly from the plenum, with the conduit communicating with the interior volume of the plenum and having an upper discharge end. The conduit is adapted and provided for extending through an aperture in the geomembrane for communicating sub-surface gas from within the interior volume of the plenum through the geomembrane. A hood is positioned adjacent an upper portion of the conduit and defines a discharge chamber therein into which gas from the discharge end of the conduit is discharged. The hood also has a discharge outlet for venting gas from within the discharge chamber to atmosphere.
