Rockfaced Blocks

Rockfaced blocks are highly decorative, close textured and extremely durable solid Dense Concrete Blocks manufactured at our Barnetts (Buglawton) plant in Congleton, Cheshire. They are a light coloured facing block whose rippled rock appearance on one face makes them an attractive option for exterior facing applications.

Their increased strength and density results in a very resilient and durable product with increased weatherproofing than a conventional dense concrete block. In commpn with all concrete blocks, they are not however completely waterproof which must be allowed for during design.

Produced to BS EN 771-3 these blocks are available in 100mm thick only with one pattern.
