The fiber reinforcing member 120 includes three layers of a lattice porous layer 121, a bristle layer 122, and a honeycomb porous layer 123. The lattice porous layer 121 has a lattice structure to form a plurality of through holes. The lattice layer 122 is formed on the lower side of the lattice porous layer 121 and the honeycomb porous layer 123, A honeycomb structure is formed to form a plurality of through holes.

When the concrete surface 10 and the sheet 110 are adhered to each other with the adhesive or mortar without the fiber reinforcement member 120, the adhesive or the mortar is cured and shrinks due to the water pressure applied to the back surface of the concrete, A gap is generated between the upper and lower portions 110 and groundwater flows into the gap and the gap gradually expands. In order to solve this problem, in the present invention, the fiber reinforcement 120 is positioned between the concrete base 10 and the sheet 110 to prevent the occurrence of a gap. The fiber reinforcement 120 has an adhesive or mortar Since the permeable adhesive or mortar is cured to increase the bonding force between the concrete base surface 10 and the sheet 110 at the time of shrinkage.

Accordingly, the mutual coupling force between the concrete base plate 10 and the lining composite panel 100 according to the present invention is strengthened, so that it is possible to prevent delamination and peeling as well as defects due to water leakage.

It is preferable that the through hole of the grid porous layer 121 is formed to be smaller than the through hole of the honeycomb porous layer 123 so that the grid porous layer 121 has a dense grid structure, It is robust and easy to use.
