Wall lining method and system

A system of lining a wall face of a landfill site comprising a series of concrete panels assembled into a wall close to the face to be lined, and a plurality of ground anchorages attaching the wall panels to said face, the anchorages being pretensioned to provide the required resistance to hydrostatic pressure, and the void between the wall and the face being filled with free-draining material, wherein the panels are cast in molds and have a synthetic low permeability sheet incorporated into one or both sides of the panel during the casting process, and the concrete panels are assembled above a mass concrete foundation channel constructed adjacent the base of the face to be lined.

A method of lining a wall face of a landfill site comprising assembling a wall of concrete panels close to the system face to be lined by ground anchorages 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, wherein the panels are cast in molds and have a synthetic low permeability sheet incorporated into one or both sides of the panel during the casting process, and each panel is an irregular hexagon.
