Abstract
Abstract An improved landscape fabric is disclosed consisting of a sheet of thermoplastic material in which a plurality of alternating hollow ridges and valleys are formed. Each of the ridges is defined by a pair of upright sidewalls and an interconnecting top. A plurality of spaced apertures are formed through each of the upright walls at its juncture with an adjacent valley, being disposed to permit the flow of water and air therethrough to the underside of the sheet while inhibiting the passage of light therethrough. The improved fabric has extensibility and flexibility during installation, permitting it to conform to the area to be covered without having to be fabric itself.
