All TexaBrick manufactured stones are the light weight exact replica of the original natural stone and the main advantage of stone veneer siding made from synthetic materials is that they are less expensive. Our manufactured stones are modeled from natural stone, to truly capture it’s beauty, texture and style. Usually made from a mixture of Portland cement, natural aggregates, and iron oxide pigments for coloration. The liquid mixture is poured into molds, where it sets into a stone-like shape. Once formed, each of the stone pieces can be set into mortar in much the same way natural stone is. The result is a durable, fireproof, very solid material that looks incredibly realistic and designed to be low maintenance.
