Block Paving Layer in Kellaways

Block Paving Layers in Kellaways — what to expect

When it comes to block paving installation in Kellaways, local contractors understand that the heavy clay soils and variable drainage of Wiltshire demand a properly prepared sub-base before a single tegula block is laid. A typical driveway or patio project here begins with excavation, followed by a compacted hardcore layer and a screeded grit sand bed, which is then graded to a precise fall so rainwater runs clear of the house and into the nearest soakaway. The blocks themselves are usually set in a herringbone bond for maximum load-spreading strength on vehicle areas, or a stretcher bond where a more linear, contemporary look is preferred for garden paths. Every install will have concrete-haunched edge courses along the perimeter, as these are what hold the whole construction together when the plate compactor passes over the surface, vibrating the blocks into a firm, even finish. However, not every job in Kellaways is a brand-new installation; many older driveways in the SN15 district have sunk in places or seen their sand joints washed out over the years. For those, a lift and relay service is the practical answer, where the affected blocks are carefully lifted, the bedding re-screeded and re-compacted, then the same blocks are put back to preserve the existing colour blend. Once the surface is true, the final stage is jointing with either kiln-dried jointing sand brushed into the gaps, or a polymeric jointing compound that is activated with a light mist of water to form a firm, weed-resistant seal. A good sealant applied after this protects the blocks from moss growth and frost damage, though it must be allowed to cure in dry weather. Householders in Kellaways considering any of this work would do well to ask a few local firms how they handle the compaction and edge restraint, and then compare quotes before making a decision.
