What is block paving?

Block paving uses discrete rectangular or shaped blocks, typically made from concrete or clay, laid tightly together in set patterns across a properly prepared foundation. Unlike poured concrete or large stone slabs, each block sits individually on a sand layer above compacted stone, allowing for flexibility and drainage.

The method requires a precise base of hardcore (broken stone) and sand to ensure blocks remain level and stable. Blocks interlock through their edge joints and are held in place by friction and edge restraint (kerbs or borders). The pattern chosen affects both appearance and performance. Common arrangements include herringbone and stretcher bonds, each distributing weight and water differently across the surface.

Block paving suits driveways, patios, and pathways in residential and light commercial settings. Its main advantage over solid surfaces is drainage: water passes between joints into the base layer rather than pooling on top, making it practical for Cheltenham's climate. Individual blocks can also be replaced if damaged, whereas a cracked slab requires larger repair work.

Proper installation matters significantly. The base needs adequate compaction, and joints must be filled with kiln-dried sand or polymeric sand to lock blocks in place and prevent weed growth. When installed well, block paving surfaces are durable and require only routine maintenance like sweeping and occasional re-sanding.
