Abstract
A mat for covering soil comprising a lower fabric layer, an upper fabric layer superimposed over the lower fabric layer, and a water absorbing material interposed between said lower fabric layer and upper fabric layer. The mat contains tubular segments containing fabric and hydraulically setting cement. The cover, when wetted, becomes ballasted by the absorbed water and the tubular elements harden to form rigid ribs that hold the mat in conformity with the surface of the underlying soil.
