Surface staying tacky or soft
If a resin driveway never fully hardens, or feels tacky in warm weather months after installation, the resin-to-aggregate ratio was almost certainly wrong, or it was laid too thick in one pass and never cured through properly.
This is a mixing and application fault, not something that improves with time. It usually means the affected area needs to come up and be relaid correctly.
Patchy or blotchy colour
Uneven colour usually comes from batches being mixed to slightly different ratios, resin being laid in patches that were allowed to skin over before the next patch joined it, or UV-unstable resin discolouring unevenly with sun exposure.
Using a UV-stable aggregate resin from the outset and laying continuously rather than in disconnected sections avoids this.
Stone loss and a rough, gritty surface
Loose stone underfoot, or the surface feeling gritty and shedding aggregate, points to under-mixing — not enough resin coating each stone to bind it into its neighbours.
A small amount of loose grit right after laying while excess is swept off is normal. Ongoing stone loss months later is not.
Cracking and pooling water
Resin-bound systems are laid over a rigid base — usually tarmac or concrete — so cracking almost always follows a crack or movement in that base underneath, telegraphing up through the resin.
Pooling suggests the falls weren't set correctly during laying, or the porous structure has become clogged with fine debris and moss, reducing how quickly water drains through it.
- Tacky or soft surface: wrong mix ratio or laid too thick
- Patchy colour: inconsistent batching or non-UV-stable resin
- Loose stone underfoot: under-mixed resin, not enough binder
- Cracking in a straight line: base movement below, not a resin fault
- Standing water: falls not set, or pores clogged with debris
What a genuine fix looks like
Localised staining or minor stone loss can sometimes be topped up in place. Widespread tackiness, colour blotching or stone loss usually can't be repaired invisibly — the affected area needs to be cut out and relaid to match.
Where the base underneath has failed, resin is a poor thing to keep patching over; the base needs addressing first or the same crack reappears.
When to consider a full replacement
If the problems cover most of the driveway, or the base beneath is failing in several places, a full strip-out and relay — done to the correct spec — is usually more cost-effective than a string of partial repairs that never quite match.
Frequently asked questions
Is resin a bad choice of surface?+
No — well-installed resin-bound surfacing is genuinely durable. Most complaints trace back to poor mixing or preparation, not the material.
Can a tacky resin driveway be left as it is?+
It won't cure on its own. Left alone it stays soft, picks up dirt and marks more easily, and generally gets worse rather than better.
Will a repaired patch match the rest of the driveway?+
We match aggregate and resin colour as closely as possible, but subtle differences can be visible, especially on an older, weathered driveway.
Does jet washing fix stone loss?+
No — jet washing can make it worse by stripping more loose aggregate. It won't rebind stone that's already coming away.
Do you offer a guarantee on resin work?+
Yes, our resin installations carry our 10-Year Guarantee, and there's No Deposit Needed to book the work in.
