Block paving fails for predictable reasons: jointing sand washes out, individual blocks sink as the sub-base settles, and weeds establish in the open joints. On older semi-detached homes common in Chigwell, original block paving driveways are now showing these signs after years of use. Lifting the blocks is the first step, but it is what the removal exposes that matters, a compacted, level sub-base in good condition is a very different starting point from one that has shifted or become waterlogged.
Once the blocks are removed and disposed of, the sub-base is inspected for compaction, drainage gradient, and any soft spots. Where the existing base is sound, it is cleaned and prepared for the resin bound surface. Where it has failed, it is broken out and rebuilt to the correct depth and compaction before any resin work begins. Front drives in Chigwell frequently feature traditional edging and kerb arrangements that are assessed at this stage and repositioned if needed.
With the base confirmed and edge restraints set, resin bound aggregate is mixed and trowelled across the surface to a consistent depth and drainage fall. The finished surface is permeable, weed-resistant, and has no open joints for sand to wash from. The itemised quote separates block removal, base preparation, edging, and the resin bound finish so every stage of the cost is visible before work starts.
