Specifying Cast Stone with Confidence

The UK Cast Stone Association (UKCSA) has a guidance note to specifiers and users on the characteristics of cast stone that can influence the choice in terms of supplier and type of cast stone units.

Choosing the right supplier

As with any building material, it’s important you can trust the manufacturer and choose a product that meets the relevant standards. Most cast stone manufacturers operate without adequate quality assurance or testing regimes and may not be working to the proper standards. Specify cast stone from this kind of supplier and you could be asking for trouble.


Cast Stone Acceptability Guidance

Cast stone is trying to replicate the appearance and character of quarried stone and cast stone items are manufactured with natural products and colour variations are inevitable and should not be a cause for rejection.

Carbon Footprint

Sustainability Statement

In terms of sustainability, cast stone performs well in both production and within its life cycles. The material is highly durable, non-toxic, re-usable and requires virtually no maintenance or repair over its long lifespan.
