Abstract

Abstract A liner for concrete forms and method for making poured concrete walls comprises a liner body constructed of insulative material and shaped for positioning between a pair of interconnected form panels. The liner body has opposing sides, one of which is positioned abutting an interior surface of a first one of the panels. The other side of the liner body as a textured, decorative surface spaced from the other panels, and is contoured for molding concrete poured therebetween. A plurality of similarly shaped liner bodies are placed in a side-by-side relationship along the interior surface of each section of form panels, with the textured surface of each oriented inwardly. Unsolidified cementitous material, such as concrete, is poured into the cavity having a single insert therein or formed between opposing inserts, and is cured to a solidified state. The form panels are disassembled and removed, and the liners on the exterior side of the dried concrete wall are bodily separated therefrom, exposing a contoured, decorative aesthetic, optionally exterior surface portion. The liners on the interior side of the wall are securely attached to the wall, thereby forming an integrated wall structure.
