Abstract
Plastic linings in the form of synthetic polymeric plastic resiliently flexible sheets are disclosed having matingly engagable connector structures along their opposing edges to permit mated engagement of adjoining sheets to form a continuous lining. The sheets have a uniform transverse cross section which extends from one end of the sheet to an opposing end of the sheet to permit extrusion of each sheet. Y-shaped engagement members are preferably provided to better secure the sheet to the surface of a concrete body of a concrete structural element being lined with the sheet. The matingly engaged connectors further provide a compression joint between mated, adjoining sheets. The sheets may also be bonded together along the joints to provide a fluid-impervious seal between the mated sheets. L-shaped synthetic polymeric plastic end members are further bonded to the sheet at corners of the concrete body where the sheets end to provide smooth, protected surfaces for coupling elements together.
