Reconstructed stone

The UKCSA is the guardian of quality for cast stone. It acts to establish and maintain the highest standards of product quality and usage and represents the leading manufacturers.

Cast stone is a special form of simulated stone, a high-quality facing material synonymous with reconstructed stone. According to the UKCSA, cast stone is any material made with natural aggregates.

Cast stone is made by using either the semi-dry or wet-cast method. It must meet the requirements of BS 1217 or the requirements of the UKCSA standard. The UKCSA developed this standard with a mix design of 35MPa. This is 40% above the basic British Standard and ensures the strongest cast stone available, with outstanding durability and site handling. It also means being able to predict precisely the performance of cast stone as a structural material. Whether design details are standard or bespoke, they can be tailored exactly to specification.

The UKCSA standard includes third party verification, comprising a rigorous regime of product testing and plant inspections.
