In short: resin bound is a smooth, permeable, trowelled mix with no loose stones. Resin bonded is a textured, gravel-look finish that is not permeable and can shed stones as it wears. For most homeowners wanting a permeable, low-maintenance drive, resin bound is the usual choice.
Side by side
| Resin bound | Resin bonded | |
|---|---|---|
| How it is made | Stone and resin mixed, then trowelled | Resin spread, loose stone scattered on top |
| Finish | Smooth, even, seamless | Textured, like gravel |
| Loose stones | None when laid correctly | Excess removed; some loosening over time |
| Permeable | Yes, if the base drains | No |
| Planning (front garden over 5 m²) | Usually no permission needed if base drains | Needs drainage to a permeable area, or permission |
| Base | Permeable build-up, or sound tarmac or concrete | Sound, impermeable tarmac or concrete |
| Feel underfoot | Smooth, good for wheels | Rougher, can be harder on bare feet |
How to tell which a quote means
Quotes and adverts often say just "resin driveway". Ask directly whether the installer will mix stone and resin and trowel it (bound) or scatter stone onto resin (bonded). If they talk about "scattering" or "broadcasting" the main aggregate, it is bonded. A fine anti-slip grit scattered on a bound surface is different and normal.
Planning
Because bonded surfaces are impermeable, a bonded front driveway over 5 m² that drains onto the road needs planning permission in England under the 2008 rules. Bound surfaces on a permeable base do not. See our planning permission guide.
Frequently asked questions
Which is cheaper?
Resin bonded generally uses less material and is often cheaper per m² for the surface layer. The base is the larger cost in either case.
Is resin bonded ever the better choice?
It gives a rougher, gravel-like texture that some people prefer, and is used on some steep slopes for grip. It must go on a sound, impermeable base such as concrete or tarmac.
