Roadstone Forticrete Abbeystone is one of the most recent developments in our Architectural Masonry range. Abbeystone adds a natural weathered appeal to the classic masonry finish.

Our unique process that gives the product a natural weather look involves shot blasting the surface of the units to expose the natural grains in the granite sands and aggregates used to produce this product.
