Abstract: 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.

Abstract: 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 geo-textiles tufted with synthetic yarns. 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.

Abstract: A system for covering (i.e., closing) various types of sites where waste is deposited comprises a composite of one or more geotextiles that are tufted with synthetic yarns and an impermeable geomembrane, which is comprised of a polymeric material. The geotextiles can comprise polypropylene or polyethylene. The cover can include wind-resistant textured synthetic blade-like elements, such as vertical filaments, secured over a low-permeable polymer liner backing. Advantageously, the system does not rely on piled-on weight to resist wind forces and the cover can be deployed over a large area with little or no ballasting or anchoring. Optionally, the cover includes vertical filaments attached to the liner to break the wind aero-dynamics on the exposed cover. With this system, it is believed that the wind velocity on the impermeable surface (membrane) now becomes turbulent near the surface of the cover, thus greatly reducing the actual wind velocity at the liner surface and decreasing associated uplift.

Abstract: A geocomposite covering for placement atop the ground and includes a lower carrier layer and an intermediate layer of particulate material positioned above the lower carrier layer. A synthetic turf is positioned over the particulate material and is affixed to the lower carrier layer to contain the particulate material between the lower carrier layer and the synthetic turf. The synthetic turf is affixed to the lower carrier layer by one or more of stitches, needle-punched staple fibers, linking fibers, heat bonded fibers, or mechanical fasteners. The particulate material can include clays, cementitious materials, granular material, powder-like material, and the like.

Abstract: A synthetic ground cover method includes placing a synthetic grass atop the ground, the synthetic grass including a composite of one or more geo-textiles tufted with synthetic yarns. The synthetic ground cover method also includes applying an infill ballast to the synthetic grass by spreading the infill ballast over and onto the synthetic grass from a moving vehicle. The infill ballast can be sand, soil, or a binding infill (such as cementitious materials).

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
