UKCSA cast stone manufacturing Full Members aim to produce products which resemble natural stone as closely as possible.
The colour and texture of most natural stone can be matched using crushed rock fines and / or carefully selected and graded natural sands, usually mixed with white cement.
The range of shades is sometimes extended by the use of grey cement and pigments.
The material can be cast either as a homogenous mix or a two part mix comprising a facing of cast stone and a backing of grey cement and aggregate.
