DENSE CONCRETE BLOCKS

Cellular offer a lower weight alternative to Solid Dense Concrete Blocks with an improved thermal performance.

These Dense Concrete Blocks are manufactured to BS EN 771-3 using high quality class 2 aggregates. These group 2 units are blinded on one bed face to allow for a full bed of mortar and their lower weight means easier manual handling. They are available in ‘Standard’ or ‘Paint-grade’ finishes.
