Wind uplift-resistant surface cover systems and method

The cover system as recited in claim 5, wherein the fibers occupy a minor portion of the thickness of the assembly and define in a majority portion of the thickness a plurality of air-flow pathways through the open-pore layer.

A method of reducing wind uplift of a cover system preventing water ingress into a surface, comprising the steps of:

• (a) providing a geomembrane layer;
• and
• (b) overlying the geomembrane layer with a wind-disturbing open-pore layer that defines an asperity extent, said open-pore layer for forming in situ an air-flow turbulence zone between the upper surface of the geomembrane layer and a boundary space proximate the open-pore layer, which boundary layer defines a transition from a turbulent flow of wind in the turbulence zone to a laminar flow of the wind remote from the geomembrane layer, said open-pore layer for inducing disturbance of the wind flow into and through the open-pore layer, whereby a suction force on the geomembrane is disturbingly broken by a plurality of turbulent wind shear events therein and said plurality of turbulent wind shear events exerting downward pressure deflections, wherein the wind speed and pressure differential lessen and the geomembrane resists uplift.
