Figures 1 and 2 illustrate cross-sectional views of the civil engineering sheet of the present invention. FIG. 1 shows an example in which the cross-sectional shape of the convex portion is semicircular, and the water-permeable layer and the water-impermeable layer are integrated by full-surface bonding. Further, FIG. 2 shows an example in which the cross section of the convex portion is trapezoidal, and the water-permeable layer and the water-impermeable layer are partially joined and integrated at the convex portion. FIG. 3 is a cross-sectional view illustrating a case where the present invention is applied between shotcrete, which is a structural base material, and lining concrete. 1: Civil engineering sheet, 2: Permeable layer, 3: Impermeable layer,
4: Convex portion, 5: Shotcrete, 6: Lining concrete.
