Cracks appearing in a resin-bound driveway
Resin Driveway Cracking: What It Means and How It's Repaired
Resin-bound surfacing is a wearing course, not a structural layer. It is only as stable as the base it sits on, so a crack in the resin is usually a crack in the tarmac or concrete beneath telegraphing upward.
Understanding that changes what a sensible repair looks like.

Reflective cracking
A straight crack that follows a line in the old base, an expansion joint or a former slab edge is reflective cracking. The resin has done nothing wrong — the base is moving.
Patching the resin alone will crack again in the same place unless the joint below is treated or bridged.
Edge and perimeter cracking
Cracking along an unsupported edge points to a missing or failed edge restraint. Resin needs something to lay against; where it feathers out over soil or a soft verge it breaks up.
Installing a proper restraint and re-laying that margin resolves it.
What repair looks like
We cut out the affected area to a clean line, address the base defect, then lay fresh resin and aggregate. Colour matching on a weathered drive is close but never invisible, so on prominent areas we sometimes recommend re-laying a whole bay to a natural break line.
Where the base has genuinely failed, the correct answer is a new base rather than another patch.
Frequently asked questions
Is cracking covered by a guarantee?
Installation guarantees cover the resin system. Movement in a pre-existing base a client asked to overlay is normally excluded — worth checking your paperwork.
Can a crack be filled?
Filling is a cosmetic measure only; the crack will reopen if the base is still moving.
How long should resin last?
A correctly installed resin-bound surface over a sound base should give many years of service, and ours is offered with a ten year guarantee.
