Block Paving Layer in New Town

Block Paving Layers in New Town — what to expect

For homeowners across New Town, the difference between a driveway that settles within a year and one that remains true for a decade usually comes down to the quality of the sub-base and the patience of the installer. Local block paving specialists in the SN8 district understand that the Marlborough area’s free-draining chalk and flint soils require a properly compacted hardcore layer before a single tegula block is placed. The standard approach involves laying a screeded grit sand bed onto that sub-base, then setting the blocks in a herringbone or stretcher bond, depending on whether the drive is predominantly curved or straight. Edge courses are always concrete-haunched to prevent lateral creep, and the whole surface is finished with a plate compactor, which is run over the paving several times to bed the blocks down fully. What many residents miss is that these are not dry-laid surfaces; after compaction, kiln-dried jointing sand is brushed into the narrow joints, then the area is compacted again to settle the sand. Where older drives in New Town have sunk or grown mossy in the joints, a lift and relay service is often the most economical solution rather than a full replacement, and a professional crew can lift, re-level, and re-lay the existing tegula blocks to restore a flush, even surface. For those who prefer a low-maintenance finish, polymeric jointing sand is increasingly popular in Wiltshire, as it hardens on the surface to resist weed growth and ant excavation, though it requires a dry, warm day to cure properly. Sealing is another matter entirely; a good water-based sealer will lock the jointing sand and deepen the block colours without leaving a glossy sheen. Any reliable contractor in New Town will first inspect the drainage falls and the existing edge restraint before quoting, since a haunched concrete edge that has failed will undermine any new work. It is always worth asking a few local installers to look at the drive, to compare the methods they propose, and to compare quotes before committing.
