Block Paving Layers in Merton — what to expect

For homeowners across Merton and the surrounding EX20 district, a well-laid block paving driveway or patio represents a considerable investment, and the quality of the initial installation determines how gracefully it ages through Devon’s wetter months. Local contractors typically begin by excavating to the correct depth, then laying a compacted sub-base before screeding a perfectly level grit sand bed upon which the blocks are set, often in a herringbone bond for maximum structural integrity or a simpler stretcher bond for a more contemporary, linear aesthetic. The edges are always the weak point, so a reputable Merton installer will secure the perimeter with concrete-haunched edge courses, ensuring the whole surface resists lateral movement over time. Once the tegula blocks are laid, the entire area is subjected to a thorough plate compaction, which interlocks the units and settles them firmly into the sand bed. After a few weeks of normal use, some homeowners notice slight settling or a few blocks becoming loose; rather than tolerate a wobbling trip hazard, a lift and relay service is often the most practical remedy, where the affected blocks are carefully removed, the underlying sand is re-levelled and re-screeded, and the blocks are then replaced and compacted once more. The final stage, jointing, is where many less experienced hands fall short: sweeping kiln-dried jointing sand into the narrow joints and then re-compacting is essential, and for an even more durable finish, many local installers now recommend polymeric jointing, which sets to a firm, weed-resistant seal after a light watering. This sealing step not only locks the joints but also protects the block faces from oil stains and frost damage, keeping driveways looking neat for years. For anyone in the wider Devon countryside considering a new driveway or simply wishing to rejuvenate an existing tired surface, the simplest way forward is to request a few independent quotations from the trusted installers listed here and compare their approach to preparation, drainage and final jointing before making a decision.
