What it is
Block paving uses individually-laid concrete or clay blocks (typically 200x100x50mm or 200x100x60mm) interlocked over a granular sub-base and bedding course, with kiln-dried sand vibrated into the joints to lock the system. The interlock - not the bedding - is what carries load.
Who it's for
Homeowners wanting a hard-wearing, repairable, vehicle-capable driveway or front-garden surface. Particularly suited to family homes with multiple cars, properties needing distinct parking and pedestrian zones, and conservation areas where colour and texture flexibility matters.
When it's needed
Replacing tarmac that has failed at the edges or cracked, converting front garden to off-street parking, after a new dropped kerb is installed, or when an existing block driveway has lost its sub-base integrity and is rutting under wheels.
Why professional installation matters
A block driveway done correctly will take 5+ tonnes per axle daily for 20+ years. Done badly, it ruts within a single winter under a family car. The variables - sub-base depth, edge restraint, bedding gradation, jointing sand and compaction - are invisible once finished, which is exactly why most failures originate there.
