Can You Repair a Resin Bound Driveway?
Updated: 3 days ago
Yes. Most cracks, holes and loose patches in a resin bound driveway can be repaired by cutting out the damaged area and relaying it with a matched mix. Where the damage is widespread, it usually means the base underneath has failed, and then the real fix is to relay that section or the whole drive rather than keep patching.
Resin bound driveways are strong and low-maintenance, but they are not immune to wear and damage. Over time, cracks, loose stones, and discolouration can appear. Many of these problems can be fixed without replacing the entire surface.
Common Types of Resin Driveway Damage
Cracks and Chips
Cracks can be caused by heavy loads, ground movement, or sharp impacts. Small ones can be repaired with a resin mix matched to the original surface.
Loose Stones
Loose aggregate is usually a sign of surface wear or poor installation. Spot repairs work for small patches, but widespread loosening often means resurfacing is needed.
Discolouration
Colour changes can come from non-UV-stable resin going amber in sunlight, chemical spills, or using the wrong cleaning products. This type of damage is usually cosmetic but can be difficult to correct without resurfacing.
What Causes Resin Driveway Damage?
In order of how often they turn out to be the cause:
Base movement. The resin layer is only 18mm or so thick, so it follows whatever the base does. A sub-base that was never compacted properly, or soft spots that weren't dug out, settle and crack the surface above them.
Laid over cracked tarmac or concrete. Resin over a sound old surface is fine; resin over a cracked one isn't. The old cracks reflect up through the new layer, often within a year or two.
Laid too thin. The resin layer should be at least three times the size of the largest stone, which means 18mm or more for a 6mm blend on a driveway. Thinner layers crack and shed stone under tyres.
Non-UV resin. Cheaper resins yellow in sunlight, which shows up as an amber cast that cleaning will not shift.
Poor mixing or wet weather on the day. Too little resin in the mix, or rain on the uncured surface, leaves a weak, crumbly or milky patch.
Point loads and dry steering. Skip corners, jack stands and turning the wheel while stationary can mark or scuff the surface.
The first three are the ones that lead to repeat repairs, because patching the surface does nothing about what's underneath. Our guide to resin driveway problems goes through how each one shows itself.
How Resin Driveway Repair Works
A proper resin driveway repair is a contractor job rather than a homeowner one. In outline:
The damaged area is cut back to a clean, straight edge with sound resin all round.
Any failed base under it is dug out, refilled and compacted.
The edges are primed so the new resin bonds to the old.
A fresh batch of resin and stone, matched as closely as possible to the existing blend, is mixed in a forced-action mixer to the system's ratio.
The mix is trowelled in to the full depth, finished to the same level and texture, and left to cure.
Keep cars off the repair until it has cured, which on a warm dry day is usually 24 to 48 hours.
Can You Repair a Resin Driveway Yourself?
Homeowners can attempt very small repairs if they have the correct materials, such as a resin repair kit for a chip or a small hole. Anything bigger is harder than it looks. Two-part resin has a short working time once mixed, the ratio has to be right, and the stone blend needs to match a surface that has weathered for years.
Achieving a good colour and texture match is challenging even for installers. Poorly matched repairs may be more noticeable than the original damage, so for anything larger than a hand-sized patch, call the original installer first, especially if the drive is still under guarantee.
When to Consider Resurfacing
If the damage is spread across much of the driveway, patching may be less effective than resurfacing. Where the base is sound, a new resin layer can go over the existing surface to restore both strength and appearance. Where the base has moved, the old surface has to come up, because a new layer over a failing base will crack in the same places.
What Does a Resin Driveway Repair Cost?
Small repairs are usually priced per job rather than per square metre, because most of the cost is getting a crew and a colour-matched mix to site. The price climbs when the damage comes from the base, since the failed section then has to be cut out, the base rebuilt and the resin relaid. Relaying a whole drive costs about the same as a new one, which is why it pays to find out why the surface failed before paying for the fix.
Preventing Future Damage
Avoid leaving heavy vehicles in one place for long periods.
Put a board under skip corners, jack stands and motorbike stands.
Avoid dry steering, especially in hot weather.
Use gentle cleaning methods to prevent erosion; our guide on how to clean a resin driveway covers what's safe.
Sweep regularly to stop grit from acting as an abrasive.
Resin bound driveways can be repaired in most cases, especially when the damage is localised. If yours keeps cracking in the same places, the base is the problem, and that is what we look at first on a site visit. We lay resin bound driveways on a properly prepared base with UV-stable resin, and every job carries our 10-year guarantee.
