Block Paving Layer in Mole Hill

Block Paving Layers in Mole Hill — what to expect

In Mole Hill, a drive or patio laid in block paving tends to start with a thorough dig-out and a well-compacted sub-base, and local installers across the CB8 district know the local clay and chalk soils well enough to get that part right first time. From there, the work typically moves on to a screeded grit sand bed, onto which the blocks are placed by hand in either a herringbone bond for strength on driveways or a simpler stretcher bond where the traffic is light, with tegula blocks often chosen for their gently curved face and ease of replacement. Edges are set on concrete-haunched edge courses so that the whole surface stays put under load, and a plate compaction pass tightens everything up before the joints are dealt with. Sand is brushed into the gaps and compacted again, but for areas that see a lot of footfall or the odd spill of oil and rain, a polymeric jointing sand is a sensible upgrade because it sets firm and keeps weeds out. Over time, a surface laid on weak ground can settle in patches, which is where a lift and relay service becomes useful: the blocks are taken up, the bed corrected, and the lot laid back down so the surface finishes level. Sealing is another matter common around here, given the damp Suffolk winters, so a good quality sealant is often worked into the blocks after a clean, to hold off moss and staining. When the job runs from foundation to finish in one go, the sequence matters more than speed, and that is what local contractors in and around Mole Hill tend to concentrate on. Anyone looking for this sort of work can ask for a few quotes and compare what is offered, including any guarantee on the sand bed and the jointing, before committing.
