The process starts with a site survey covering base condition, existing drainage fall, and ground stability. Huntingdon properties often have older concrete or tarmac that needs assessing before an overlay is possible. Where the existing base is sound, preparation involves cleaning, crack repair, and priming. Where it is not, excavation removes the old surface and a compacted MOT Type 1 sub-base is laid to the correct depth for the ground conditions.
Aggregate is selected at survey stage from physical samples, allowing colour and stone size to be matched against the property’s brickwork or boundary materials. The resin binder and aggregate are mixed together, then hand-trowelled to a consistent finish across the surface. Edge restraints are installed before the resin layer to hold the material at the perimeter and define the finished line.
Drainage fall is checked before the resin is applied, water needs to clear the surface towards a channel or boundary, not pool at the base of the house. On new Cambridgeshire builds, drainage patterns are assessed as part of the survey. Cure time before vehicle use is typically 24 hours in dry conditions. The permeable structure of a resin bound surface means it meets SuDS rules, removing the need for planning permission on most front driveways.
