Abstract
An object retention form liner is described for use in holding and transferring objects, such as thin bricks to the finished surface of concrete structures. The form liner is produced by strategically positioning a plurality of bricks in a face-up position in a flat, shallow mold. Recesses sized to fit the bricks can be provided in the surface of the mold with a sealing ridge provided between each of the recesses. The bricks are positioned in the recesses and a liquid elastomeric material is poured into the mold to cover the bricks. Reinforcing fiberglass mesh can be embedded in the elastomeric material to provide additional tensile strength to the liner. Upon setting, the liner and retained bricks are removed from the mold and the liner can be stored, shipped or used in concrete construction. The liners are attached to the inside surface of concrete forms and the bricks are held rigidly in place while the concrete is poured and sets. Upon removal of the form and liner, the bricks remain permanently embedded in the surface of the concrete structure providing an improved aesthetic appearance. Through the gasketing effect that is obtained by embedding the outer surface of the bricks …
