SOLID DENSE CONCRETE BLOCKS

Our Solid Dense Concrete Blocks with a ‘Standard’ finish provide an excellent surface for mortars, renders and plasters. They are the most durable and resilient block in our product range, making them perfect for higher strength, acoustic and highly resilient applications.

Dense blocks are available in two finishes, the ‘Standard’ texture finish provides an excellent surface for mortars, renders and plasters, whereas the ‘Paint-grade’ close textured finish provides a smoother surface, making this ideal for internal paint-grade applications.

Dense Blocks are readily available in a design of solid, cellular and hollow configurations offering a flexible choice of design requirements with a standard face size of 440mm x 215mm. All dense blocks are manufactured from high quality class 2 aggregates, consisting of up to 30% recycled raw material and are suitable for use above and below damp-proof course (DPC).

Dense blocks are manufactured to BS EN 771-3 and are ISO 9001 Quality Assured, ISO 14001 Environmentally Certified and hold BES 6001 ‘Excellent’.
