Quality & Standards

All Ilam stone products are cast in timber, resin or steel moulds. All moulds are constructed to a high degree of accuracy from workshop drawings produced in house using the latest CAD facilities. Our own skilled mould makers produce most of the moulds required.

Many individual designs are inspired by classical architecture or more decorative styles. These unusual sizes, intricate or irregular shapes and special colours can,in most cases, be made to suit your particular project. We will liaise with your designer or architect to create purpose-made products to your specifications.

Sourced from naturally occurring high-grade limestone and sandstone aggregates together with cement, pigments and waterproofing agents, Ilam Stone Architectural Cast Masonry is manufactured to BS 1217:2008 specification for ‘Semi Dry’ products. Kiwa Construction Material Testing, a Derby-based independent laboratory, carries out periodic testing of products for both crushing strength and capillary absorption. Copies of the results are available on request.
