Description

Our 140mm Solid Dense Concrete Blocks are the professional choice for structural work where strength and stability are the primary requirements. Wider than the standard 100mm block, this 140mm unit is ideal for constructing foundations, heavy-duty retaining walls, and the inner leaves of external cavity walls that require high load capacity.

Manufactured from dense aggregate concrete with a compressive strength of 7.3N/mm², these blocks are extremely durable and resistant to moisture. Their high mass makes them particularly effective for sound insulation in separating walls (party walls) and flanking walls. They are suitable for use both above and below the Damp Proof Course (DPC) and as infill for beam and block flooring systems.
