Following the acquisition of the Johnston Quarried Group in January 2022, the Group established its England Platform focusing on quarried and mined limestone for the construction market.

Johnston is a specialist quarried materials supplier producing construction aggregates and premium quality building stone, as well as agricultural lime for soil improvement. Its aggregate products are typically used in infrastructure projects, with its unique Cotswolds Ironstone and Bath Stone used in specified high-end housing applications. The business currently consists of four quarries, three mines and two separate stone processing sites located across the Southwest, Oxfordshire, and Lincolnshire. Johnston has access to tonnes of freehold and leasehold reserves giving it an average life of over 40 years.
