Resin Bound Driveways
A seamless, permeable driveway surface made from natural stone aggregate bound in clear UV-stable resin, laid over a prepared base.
What resin bound surfacing actually is
Resin bound surfacing is natural stone aggregate, usually a blend of granite, quartz or marble chippings, mixed with a clear polyurethane resin in a forced-action mixer and trowelled out on site while wet. Every stone is coated, so the finished surface holds together as a single seamless mat with small voids between the stones that water passes through.
That last point is what separates it from almost every other driveway surface. It is permeable by construction rather than by drainage design, which is why it sits outside the planning restriction on impermeable front garden surfacing in England.
It is not the same thing as resin bonded surfacing, despite the names. Resin bonded is a layer of resin spread onto a base with dry stone scattered over the top, giving a rougher, loose-looking finish that is not permeable and sheds stone over time. The two are frequently confused, sometimes by people selling them.
What a proper installation involves
The base determines the lifespan, and it is where a cheap quote is usually cheap. Over an existing driveway, the surface is assessed for structural soundness, cleaned, any cracks cut out and repaired, and edges formed. Over bare ground, the area is excavated to depth, edge restraints set, and a permeable sub-base of open-graded stone laid and compacted in layers, usually with a binder course over it.
The resin and aggregate are then mixed in measured batches and trowelled to a consistent depth, typically 15 to 18 millimetres for a driveway taking vehicles. Depth matters: a surface laid thin to stretch the materials will fail under wheel loading regardless of how good it looks on the day.
Because it is mixed and poured wet, the work is weather dependent. The surface needs to be dry and above roughly five degrees while it cures, and rain within the first few hours can ruin a fresh pour. A competent installer reschedules rather than gambling, and it is worth being suspicious of one who does not.
Curing and first use
You can usually walk on a new resin bound surface after around six hours, and drive on it after 24 to 48 hours depending on temperature. Colder conditions extend both. Turning a car sharply on the spot should be avoided for the first week or so, since a power-steering scuff on a green surface can mark it.
The surface reaches full strength over the following days. Beyond that, maintenance is minimal: an occasional wash, and prompt attention to any oil spill rather than letting it sit.

Common questions
How long does a resin bound driveway last?
A properly installed surface on a sound base is generally expected to last in the region of fifteen to twenty years. The dominant variable is the base, not the resin: a well-laid surface over a poor sub-base will fail long before a well-based one, and no resin system compensates for ground that was never prepared. Sunlight is a secondary factor, which is why the binder should be a UV-stable polyurethane rather than a cheaper epoxy that ambers over time.
Does a resin driveway go green or grow weeds?
Far less than gravel or block paving, but it is not immune. There is no soil in the surface and no joints for seeds to root in, so weeds cannot establish from below the way they do between blocks. What can happen is that airborne dirt and organic debris collect in the surface voids over years, and moss or algae take hold in permanently shaded, damp spots. An occasional wash deals with it, and keeping overhanging vegetation cut back does more good than any treatment.
Can it be repaired if it gets damaged?
Yes, though a repair is usually visible. Damaged areas can be cut out and refilled with a fresh batch of the same blend, which bonds to the surrounding surface. The honest caveat is colour: a new pour against a surface that has weathered for several years rarely matches perfectly, and the join tends to show for a while before it settles. Keeping a note of the exact aggregate blend used makes a future repair considerably easier.
Is resin bound slippery when wet?
No, and it generally performs better than a smooth sealed surface. The finish is open textured rather than polished, which gives it grip in the wet. This matters a great deal on the sloping driveways common around Plymouth and Torquay. Where a gradient is significant, aggregate size and mix can be adjusted to increase texture further, which is a conversation to have on site.
