Abstract: A cover system for preventing water ingress having a geomembrane layer and a wind-disturbing open-pore layer thereon and defining an asperity extent, said open-pore layer for forming in situ an air-flow turbulence zone between the geomembrane layer and a boundary space proximate the open-pore layer as a transition from turbulent flow of wind in the turbulence zone to laminar flow of the wind remote from the geomembrane layer, said open-pore layer inducing disturbance of a wind flow into and through the layer, whereby a suction force on the geomembrane is disturbingly broken by turbulent wind shear events therein and exerted downward pressure deflections, wherein the wind speed and pressure differential lessen and the geomembrane resists uplift. A method of covering a large area surface with a cover system that resists wind uplift is disclosed.

Abstract: A turf joining system including a first piece and second piece of a synthetic turf and a bridge support. The first and second pieces have side edges which are closely adjacent each other. The bridge support heat welds to the overlying first and second pieces to form an elongated first heat weld and elongated second heat weld each proximate and spaced from the respective side edge to define a water channel therebetween. A method of sealing a plurality of synthetic turf pieces together is disclosed.

Abstract: A photovoltaic module with bottom mounting brackets attached to a first side and each having an extending flange with a top surface of a first character and top mounting brackets attached to a second side and each having an extending flange that defines a bottom surface of a second character, the flanges of the top mounting brackets extending over and engaging the flanges of the bottom mounting brackets of another of the photovoltaic modules, whereby the interconnected modules resist sliding separation during installation. A method of holding adjacent photovoltaic modules during installation on sloped surfaces is disclosed.

Abstract: An elongated plate having a rail and defining lateral wings on opposing sides and a plurality of spaced-apart tabs extending below a plane defined by a bottom surface of the plate for engaging a tufted geotextile ground cover, said rail for receiving a fastener for engaging a bracket of a photovoltaic module thereto. Alternatively, a pair of U-shaped racks support adjacent photovoltaic modules in a series on a support surface, comprising a base and a pair of opposing elongated legs each having a support plate for supportingly engaging a respective one of two adjacent photovoltaic modules, and the base including spaced tabs projecting at an angle to dispose a respective distal end vertically spaced from a bottom surface of the base, for engaging a portion of the support surface.
