Abstract: The invention relates to a method for reinforcing a civil engineering structure, comprising the following steps: —coating a surface of the structure with a first layer of resin in a fluid state, having a particle size distribution, termed first particle size distribution, —applying a layer of a dry woven fabric with a weight per unit area greater than or equal to 600 g/m2, termed high-grammage woven fabric, to the coated surface while the resin is still in the fluid state, by exerting on the woven fabric a pressure sufficient to impregnate it with resin, —coating the woven fabric with a second layer of resin, termed closure layer, in a fluid state, having a particle size distribution, termed second particle size distribution, which is less than or equal to the first particle size distribution.

Abstract: The invention relates to a method for erecting a structure 0 comprising at least two prefabricated concrete elements 1, 2, the method comprising: installing a first concrete element 1; placing a second concrete element 2 with at least one spacer 4 maintaining a gap between respective end faces 104, 203 of the first element and second element; tensioning at least one bar 105, 3 held on the first and second elements and passing through the gap maintained by the spacer, and introducing a hardenable interface product 5 into said gap. The method thus makes it possible to move off the critical path relating to the erection the need to wait, between two assembly operations, for the joints between the assembled pieces to have hardened. Incidentally, a significant reduction in the time taken for erecting such a structure is obtained.
