What is block paving?

Block paving consists of small rectangular or decorative concrete or clay units laid individually on a bed of sand, which sits above a compacted sub-base of stone or similar material. The blocks interlock or sit tightly together, creating a continuous surface that can move slightly without cracking, unlike rigid alternatives such as poured concrete or asphalt.

The key advantage of block paving is its flexibility and drainage. Because each unit is independent, the surface can expand and contract with temperature changes without generating stress cracks. Water drains between the joints into the sand bed and sub-base, making it suitable for areas with wet climates like Cheltenham. If a single block becomes damaged, it can be replaced without affecting the rest of the surface.

Block paving is widely chosen for driveways, patios, and garden paths because it offers visual appeal (available in various colours and finishes), practical durability, and a relatively long lifespan with proper installation and maintenance. The method differs fundamentally from concrete slabs (which are larger and rigid) or tarmac (which is fluid-applied and less permeable).

Professional installation is important to ensure the sub-base is properly compacted and the sand bed is at the correct depth and firmness, as poor preparation can lead to sinking or movement over time.
