ABSTRACT:
A method of lining a wall face comprises assembling a wall of concrete panels (16) close to the face to be lined, attaching the panels to the face to be lined by ground anchorages (12) pretensioned to provide the required resistance to hydrostatic pressure, the anchorages being grouted into the face at one end, and anchored to the respective panel at the other end, and filling the void between the wall and the face with free-draining material (14). The invention also relates to a system of lining a wall face using concrete panels and ground anchorages. Preferably the panels are cast in molds and have a synthetic low permeability sheet (29) incorporated into one or both sides of the panel during the casting process.
