Even if waterproofing is only a small amount of the whole cost of the project, it is a key component of the structure for the high impact of possible damages and inefficiencies. Therefore, the long-term efficiency of this component is of great importance. In this paper, two important aspects have been developed to correctly consider this issue.
Moisture protection and waterproofing
Published in Gary Anglin, Introduction to Estimating, Plan Reading and Construction Techniques, 2019
The NRCA defines damp-proofing as the treatment of a substrate to “resist the passage of moisture”. Waterproofing is defined as the treatment of a substrate or structure to “prevent the passage of water under hydrostatic conditions” (which means the presence of water and water pressure).

Physical and numerical models of pressure during waterproofing injections with polymer into concrete fractures

Waterproofing injections consists in the injection of a polymeric product with a pump inside the fracture. A constant flow or injection pressure is used. A sealing product is sometimes applied on the fracture trace at the concrete surface to keep the polymer inside the fracture (Trout, 2006). The target viscosity is generally low to ensure the penetrability of the liquid throughout the fracture (Emmelin et al., 2007; Karol, 2003). Acid, detergents or solvents are sometimes used to clean the fracture before the injection, but the importance of cleaning and the fluid that should be used remain controversial (Trout, 2006; von Fay, 2015). The polymeric products that are generally used in all types of injections are epoxy, acrylamide, resorcinol-formaldehyde, calcium acrylate (Association française des tunnels et de l’espace souterrain [AFTES], 2005; U.S. Army Corps of Engineers, 2004) and polyurethane (Andersson, 1999).
