Abstract
A reinforced civil engineering structure is formed by embedding in soil one or more horizontal layers of a flexible, integral, plastics material mesh structure having oriented strands and transverse members with relatively large mesh openings. In the mesh structure, the orientation of the strands penetrates into the zones of the intersections of the strands and transverse members but the intersection zones have portions which are unorientated or substantially less orientated than the mid-points of the strands. The mesh structure has been formed by stretching a sheet of starting material having a thickness of not less than 1.5 mm and a pattern of holes whose centers lay on a square or rectangular grid, the stretching being parallel to one of the axes of the grid. The soil engages in the mesh openings, and the mesh structure provides good slip resistance properties and good stress transmission paths.
