PROBLEM TO BE SOLVED: To form a resin film enough to guard ultraviolet light by coating of mesh woven or knitted fabric for civil engineering having a prescribed scale of mesh with a resin and retain tensile strength by forming a specific film laminate sheet and subjecting a film part to punching processing. SOLUTION: A thermoplastic resin film (thickness is preferably 0.5-10mm) 2 is attached along the both faces of mesh like woven or knitted fabric 1 using polyester, polypropylene, polyethylene, nylon and aramid fiber and pressure is applied thereto by a heat press machine or calender roll 5 and the thermoplastic resin film is melted and bonded to the mesh-like woven or knitted fabric 1 by heating to form a film laminated sheet 3 and the film part is punched and the mesh woven or knitted fabric for engineering works having scale of mesh from 2mm×2mm to 200mm×200mm in both of weft and warp is coated with a resin. Furthermore, tensile strength of mesh sheet 4 has 1-20tf/m in both of weft and warp.
