215mm Hollow Dense Concrete Block 7.3N

215mm hollow dense concrete block with a compressive strength of 7.3N/mm², measuring 440mm x 215mm x 215mm. Manufactured from a dense aggregate mix with central voids, it combines reliable load-bearing strength with easier handling and reduced dead weight compared to solid units. The hollow format also allows reinforcement or insulation to be introduced into the cores, making it a versatile option for foundations, external walls, partitions, and structural walls above or below DPC.
