DECORATIVE FACING CONCRETE BLOCKS

Our Rockfaced blocks are highly decorative, close textured and extremely durable solid dense concrete blocks manufactured at our Congleton and Aintree facilities. They are a light-coloured facing block whose rippled rock appearance on one face makes them an attractive option for exterior facing applications.
