PURPOSE:To improve the water permeability and settleability in water of a sheet by using a sheet formed integrally of a woven fabric and/or a nonwoven fabric of a synthetic resin filament and hydraulic substance for civil construction work. CONSTITUTION:A sheet for civil construction work is the one formed by integrating a woven fabric and/or a nonwoven fabric of synthetic resin filaments and a hydraulic substance. The woven fabric is formed by weaving bulky filaments and has enough voids to be packed with a hydraulic substance in the same amount as its own weight. The nonwoven fabric is formed by bundling filaments into a form of sheet by needling, etc., having enough bulkiness and voids to be filled with a hydraulic substance in an amount more than its own weight. The hydraulic substance used is composed of cement, mortar, etc. The hydraulic substance is permeated into the woven fabric and/or the nonwoven fabric to obtain a sheet so as not to float on water for civil construction work. |
