Block Paving Layer in Cambridge

Block Paving Layers in Cambridge — what to expect

For homeowners across Cambridge and the surrounding villages, the longevity of a block paved driveway or patio depends far more on the quality of the preparation beneath the surface than on the blocks themselves, and local installers in this part of Norfolk understand that distinction well. A proper installation begins with a well-compacted sub-base, followed by a screeded grit sand bed that is levelled meticulously to ensure a uniform fall for drainage, before tegula blocks or, for that matter, any rectangular paving unit, are laid in a herringbone bond to spread the load of vehicles effectively, with a stretcher bond reserved for lighter-use paths. The edges, where so many jobs fail, are finished with concrete-haunched edge courses to lock the whole area together, and the entire surface is then subjected to multiple passes with a plate compactor to settle everything into place. When a driveway has been down for a decade or more, a lift and relay service is often the more cost-conscious approach, where the blocks are carefully lifted, the old sand bed is replaced, the edges are re-haunched if needed, and the blocks are realigned before the plate compactor returns for a thorough consolidation. Fresh installations will then receive a sweeping of kiln-dried jointing sand, vibrated into the gaps, and for those who prefer a more robust finish, a polymeric jointing product is brushed in and activated with water, which hardens to resist weed growth and ant infestation, though it must be applied on a perfectly dry day to be effective. Sealing the blocks themselves, whether they are tegula or another tumbled style, is a final step that some choose for a subtle sheen and to make oil spills easier to clean, but it is a task best left to the same experienced hands that did the laying. Across the NR10 postcode area and the wider Norfolk market, contractors are consistently busy, and the simple way to make an informed choice is to look at the finish of the joints and the straightness of the edging on completed work, and then to invite a few different installers to assess the site and provide their own written quotations side by side.
