Block paving that has cracked, sunk, or shifted has usually done so because the sub-base beneath it has moved or failed to drain correctly. Peterborough’s clay-heavy ground is a common cause, clay expands and contracts with moisture, gradually destabilising the base. Overlaying a new surface on top of this does not fix the underlying movement; it reproduces the same failure in the new material within a few years.
Removal starts with lifting the existing blocks and clearing the jointing material. The sub-base is then inspected for compaction, drainage performance, and level. Where the sub-base has failed, it is repaired or rebuilt to the correct specification before anything else proceeds. This inspection stage is what separates a lasting installation from one that begins to crack and sink again within a season.
Once the base is confirmed sound, edge restraints are set to the correct drainage falls and the resin bound aggregate is mixed and trowelled across the surface. The finished surface is permeable, weed-resistant, and requires no re-sanding or re-jointing. Every quote separates block paving removal, sub-base inspection and repair, and the resin bound finish as individual line items.
