Sprayed concrete is used as the first cover layer in the construction of tunnels; it generally is not required to perform any other function. Two examples of successful waterproofing of tunnel constructions are cited below. The first example describes a mine-access tunnel with water ingress from the mountain, while the second outlines the waterproofing of a pressurized water tunnel. In the tunnel sections under consideration, waterproofing was achieved by polymer modification. An inspection after a two-year service life revealed that impermeability was undiminished. The second example describes the renovation of a pressurized water tunnel, where water loss from the tunnel into the mountain was reduced. After two years of operation, an inspection showed that the sprayed-concrete shell was still intact.
