Abstract

PURPOSE: To intercept spring water by a method wherein projecting parts are provided on one surface of a base sheet made of a water-impermeable material, while a water-permeable material is stuck fast on the other surface, and thereby passages are formed on both surfaces of the sheet. CONSTITUTION: A base sheet 2 made of hard synthetic resin which has projecting parts 2b shaped like projecting-truncated-cone-shaped projections, disposed discontinuously and regularly and formed integrally to be hollow, on one surface of a base part 2a of a flat sheet made of a water-impermeable material such as vinyl chloride, is molded and a water-permeable material 3 of nonwoven fabric or the like is stuck fast on the other surface of the sheet 2. A waterproof sheet 1 is constituted by forming water passages 5 and 6 on both surfaces of the sheet 2 respectively. According to this constitution, spring water or the like can be discharged by providing the sheet 1 between primary concrete and secondary concrete and, therefore, the durability of an underground structure can be improved.
