摘要

A surface protective coating for controlling the erosion applied to the floor, coating comprising a flexible support means in the form of a liquid-permeable sheet adapted to the contour of the floor, and a carpet of blocks placed on said support medium or sheet said carpet being constituted by a plurality of blocks arranged essentially abutting side by side, and said carpet having drainage passages that pass through it and extend from an upper surface of said carpet to the lower surface of the same to give communication from said upper surface to said sheet or support means so that the liquid can pass in one direction or the other between said upper upper surface and the ground through said support sheet and said carpet.
