SOIL COVER MEMBRANE WITH A PLURALITY OF DISCREET, DISTRIBUTED, AND ADHERED DISCRETE ROUGHNESS ELEMENTS, AND METHOD

Abstract

A ground cover (10) comprising an elongated thermoplastic membrane (12) having a thickness (18) and a plurality of discrete structural roughness elements (28) fixed (by fusion or adhesive) at spaced intervals with respect to an upper surface of the membrane to define a high profile with a distal extension of the high profile spaced vertically from the upper surface for improved resistance to wind shear forces. The ground cover is manufactured by a method comprising the steps of (a) forming an elongated thermoplastic membrane; and (b) fixing (by fusion or adhesive) a plurality of discrete structural roughness elements to define a high vertical profile for improved resistance to wind shear forces.
