Methods and apparatus for providing linings on concrete structures

Abstract

Methods and apparatus are provided for lining one or more surfaces of concrete structures during fabrication thereof. A structure-lining apparatus comprises a plurality of structure-lining panels and a plurality of concrete-anchoring components. The panels, which may extend in longitudinal and transverse directions, are interconnected to one another in edge-to-edge relationship at their transverse edges to line at least a portion of the interior of the structural form. The concrete-anchoring components extend in an inward/outward direction from the panels. The concrete-anchoring components may: be integrally formed with the panels; connect to the panels via suitably configured connector components; and/or connect edge-adjacent panels to one another. The concrete-anchoring components may comprise concrete-anchoring features which may extend in the longitudinal and transverse directions (e.g. in a plane parallel to the panels) to provide concrete-anchoring surfaces. In particular embodiments, the concrete-anchoring features comprise a stem which extends in the inward/outward and longitudinal directions and, at a distance spaced apart from the panels in the inward/outward direction, one or more leaves which extend in the longitudinal and transverse directions to provide anchoring surfaces. Concrete is then poured into the form on an interior of the lining panels and allowed to solidify in the form. As the concrete solidifies, the concrete-anchoring components bond the lining panels to the resultant concrete structure.
