Article describes a cast-in-place concrete wall system that delivers the beauty of stone at a fraction of the cost. The patented wall system uses form liners molded from natural rock surfaces to produce a deep-relief pattern in concrete that replicates an actual stone-and-mortar wall. Available in a variety of patterns, the liners can be bolted onto standard concrete wall forms and are made of a durable urethane that provides multiple reuses. The liners come in a 2x6-foot size for straight walls and in various corner, post and filler sizes. For easier stripping, the liners can be coated with a nonstaining release agent.
