Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
86 words
A flexible, rollable mat adapted to be unrolled along a surface supporting a body of water, said mat comprising: a flexible, generally sheet-like matrix fabricated from a polymeric material and having a plurality of discrete particles of a weighting material retainably embedded therein, the density and amount of said weighting material being sufficient to cause the mat to sink beneath the body of water; said mat further including a plurality of spaced apart openings extending therethrough and configured to allow passage of water and gas therethrough.
Claim 2
Dependent Claim
86 words

Claim 3
Dependent Claim
44 words
A mat as in claim 1, wherein the density and amount of weighting material confers sufficient density to the mat so as to cause compression of the surface upon which it is disposed so that water is displaced therefrom and said surface is firmed.
