PROBLEM TO BE SOLVED: To provide a sheet for civil engineering materials excellent in impact resistance to gravel by enhancing chemical resistance of para aramide base fibers. SOLUTION: The sheet for civil engineering materials comprises a mesh sheet composed of sheath-core structural yarns comprising high-strength fibers which have≥20 cN/dtex of tensile strength at break,≥450 cN/dtex of tensile modulus, covered with fibers composed of other materials, at least the high-strength fibers are coated with a synthetic resin.
