Abstract
Abstract A ground cover for controlling soil erosion and retarding vegetation growth on sloped ground includes a plurality of spaced apart water control baffles and a series of thin, sheet-like membranes between pairs of the water control baffles. The ground cover is secured to the ground by a plurality of ground engaging fasteners. The water control baffles preferably include a vertical leg having a plurality of apertures therethrough, and a ground engaging leg, which is substantially horizontal to the ground, for receiving the ground engaging fasteners. The membranes allow water to flow through the membrane while preventing erosion of the soil underneath the membrane.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
65 words
A ground cover for controlling soil erosion and retarding vegetation growth on sloped ground comprising: a thin, sheet-like membrane; and a water flow control baffle comprising a vertical leg having a plurality of planar apertures therethrough; said membrane for placement on the sloped ground with said water flow control baffle placed thereon to control soil erosion and to retard vegetation growth on the sloped ground.
Claim 2
Dependent Claim
65 words
A ground cover for controlling soil erosion and retarding vegetation growth on sloped ground comprising: a thin, sheet-like membrane; and a water flow control baffle comprising a vertical leg having a plurality of planar apertures therethrough; said membrane for placement on the sloped ground with said water flow control baffle placed thereon to control soil erosion and to retard vegetation growth on the sloped ground.
Claim 3
Dependent Claim
52 words
A ground cover according to claim 1 wherein said water flow control baffle further comprises a ground engaging leg substantially horizontal to the sloped ground, said ground engaging leg having a plurality of apertures therethrough for receiving a corresponding plurality of fastening means for securing the ground cover to the sloped ground.
Claim 4
Dependent Claim
27 words
A ground cover according to claim 2 wherein said vertical leg and said ground engaging leg of said water flow control baffle define an L-shaped cross section.
Claim 5
Dependent Claim
27 words
A ground cover according to claim 2 wherein said vertical leg and said ground engaging leg of said water flow control baffle define a T-shaped cross section.
Claim 6
Dependent Claim
25 words
A ground cover according to claim 1 wherein said membrane is water permeable to allow water to flow through the membrane into the sloped ground.
Claim 7
Dependent Claim

Claim 8
Dependent Claim
29 words
A ground cover according to claim 1 wherein said water flow control baffle further comprises a brace fixed at one end to said vertical leg and extending outwardly therefrom.
Claim 9
Dependent Claim
16 words
A ground cover according to claim 7 wherein said brace has at least one aperture therethrough.
Claim 10
Dependent Claim
36 words
A ground cover according to claim 1 comprising: a plurality of said water flow control baffles spaced apart; and a plurality of said membranes, each positioned between a pair of said plurality of water control baffles.
Claim 11
Dependent Claim
42 words
