Block Paving Layer in Kingsdown

Block Paving Layers in Kingsdown — what to expect

For householders across Kingsdown, the standard of block paving installation in SN2 has matured considerably over the past decade, with local contractors now routinely preparing a properly screeded grit sand bed over a compacted sub-base before laying tegula blocks in either a herringbone or stretcher bond, depending on the driveway’s proportions and load requirements. The full process, as practiced by established Wiltshire installers, begins with excavation and the careful levelling of a MOT Type 1 sub-base, which is then consolidated with a plate compactor to prevent future settlement, before the screeded grit sand bed is struck off to a consistent depth of around forty millimetres. Edge restraints are not an afterthought in this part of the county; competent firms invariably set concrete-haunched edge courses along any boundary or adjacent path, as a poorly supported perimeter is the most frequent cause of later slippage and unevenness in the surface. Once the blocks are laid and vibrated into place, the finishing stage involves brushing kiln-dried jointing sand into the gaps and then re-compacting the whole area, often followed by a further application of sand to top up any voids left by the vibration process. For those with an older driveway that has developed dips or moss in the joints, a lift and relay service is a practical alternative to a full re-lay, where the existing blocks are carefully lifted, the bed re-graded and re-tamped, and then the original blocks are reused with fresh edge restraint. More recent additions to the trade in Kingsdown include the use of polymeric jointing, which sets to a firm, yet permeable, binder that resists weed growth and ant activity for several years, though this requires precise dry conditions during application. Regardless of the chosen method, sealing is often recommended after a few weeks to enhance the colour of the blocks and to make future cleaning easier, though it is not always essential for a sound, level finish. For a calm and considered decision, it is always wise to obtain a few written quotes from the established trades in the SN2 district, as this allows one to weigh up the proposed depths, materials and warranties without any pressure.
