What is block paving?

Block paving consists of individual units, usually concrete or clay, set closely together on a prepared foundation. Each block is laid on a compacted sub-base (typically crushed stone or hardcore) and a sand bed, with sand also brushed into the joints between blocks to lock them in place. This interlocking system distributes weight evenly and allows for some movement without cracking.

Standard block sizes range from 200 x 100mm to 225 x 112mm, though larger and smaller options exist. Blocks can be laid in various patterns: herringbone, basket weave, running bond, and perpendicular arrangements are common choices. The choice of pattern affects both the appearance and the structural performance of the finished surface.

Block paving differs from poured concrete slabs or rigid paving because the individual units can shift slightly without compromising the surface. This makes it popular for driveways, patios, and pathways in the Cheltenham area, particularly on properties where ground movement or settling is a concern. The material also offers straightforward repair: if one or more blocks become damaged, they can be replaced without affecting adjacent sections.

When installed correctly by a qualified contractor, block paving typically lasts 15-25 years or longer. Over time, weeds may emerge in joints and the sand bed may need occasional topping up. Find local block paving contractors to assess your site and recommend the best material and layout for your needs.
