Resin-Bound Driveways: What You Need to Know

Resin-bound vs resin-bonded

These sound the same but are very different:

• Resin-bound: stones are mixed with resin before laying, then trowelled smooth. The finish is smooth, permeable and has no loose stones. This is what most people mean by a resin driveway.
• Resin-bonded: a layer of resin is spread on the base and loose stones are scattered on top. It has a rougher, gravel-like texture, isn't permeable, and loose stones can come away over time.

How thick is it laid?

Driveways: usually 18mm, with smaller stones (typically 1–3mm and 2–5mm, sometimes 6mm).

Paths and patios: often 15mm.

It sounds thin, but the strength comes from the base underneath, not the resin layer.

What base does it need?

Resin-bound must go on a sound, stable base – usually tarmac or concrete. It can go over an existing surface if that is in good condition with no cracks, movement or sinking. Otherwise you need a new base: typically around 150mm of compacted MOT Type 1 (or a permeable Type 3 sub-base if you want the whole driveway to drain) with a layer of porous tarmac or concrete on top. Laying resin over a failing base is the most common reason resin driveways crack.

How much does it cost?

For a professional installation, expect roughly £60–£120 per m² in 2026, depending on the resin system, the stones, and how much base work is needed. A typical 60m² driveway often lands somewhere in the region of £3,500–£5,500. New base work adds to that.

How many kits for DIY?

DIY kits are sold as bags of stones with a matching tub of resin. A typical kit covers roughly 3–3.5m² at 18mm. The Resin-Bound Driveway Calculator works out how many kits you'll need for your area and depth. It's a job to take on only if you're confident. Resin starts curing quickly once mixed, so you need a mixer, a team and a plan for each section.

Pros

• Smooth, modern finish with lots of colour options
• Permeable, so usually doesn't need planning permission in front gardens (on a permeable base)
• No loose stones or ruts
• Weeds struggle to grow through it
• Wheelchair- and pushchair-friendly

Cons

• Needs a sound base, which can double the cost if yours needs replacing
• Hard to patch invisibly
• Can't be laid in rain, frost or very cold weather
• Cheaper resins can yellow in sunlight – ask for UV-stable (aliphatic) resin for lighter colours
• Quality varies a lot between installers

Choosing an installer

Ask what resin system they use, whether it's UV-stable, what base they'll lay on, what the guarantee covers, and to see driveways they laid a few years ago. Be wary of very cheap quotes – the savings usually come from skipping base preparation.
