Abstract
A cladding for a partially-overhanging substrate, such as a tunnel wall which comprises in sequence, from the tunnel wall, a drainage means, a sprayed polymeric membrane and a final layer of concrete. The cladding gives an effective cladding in conditions where the tunnel walls suffer from running water at the time of cladding, is easier to apply and requires less material.
