Abstract: Α 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 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.
