The inaugural meeting of the United Kingdom Cast Stone Association (UKCSA) was held on 20th February 1991, following discussions during late 1990 between the leading manufacturers of cast stone at the time. UKCSA was formed as an independent trade association to increase specifiers’ and contractors’ awareness and confidence in cast stone and to establish and maintain the highest standards of product quality and usage. In February 2021 the Cast Stone Association celebrated its 30th anniversary as the guardian of quality for cast stone, and has grown to become the first point of reference for all matters regarding cast stone. UKCSA is an ethically, socially and environmentally responsible trade association. The Association represents the leading UK manufacturers of cast stone, and associated trades . All cast stone manufacturing Members must comply with the criteria established by the Association as a condition of membership.
