Driveway Groundwork Cost in the UK
Groundwork is often the hidden cost in a driveway project. Understanding what's involved — and what it costs — helps you budget realistically and avoid surprises when quotes come in.
Groundwork Cost Breakdown
| Work | Cost Per m² | 50 m² Cost |
|---|---|---|
| Excavation (150mm depth) | £15–£25 | £750–£1,250 |
| Sub-base (Type 1 MOT, compacted) | £15–£30 | £750–£1,500 |
| Skip hire (spoil removal) | Flat fee | £200–£350 |
| Membrane installation | £2–£5 | £100–£250 |
| Total groundwork | £25–£50 | £1,250–£2,500 |
When Is Groundwork Needed?
Groundwork is needed when the existing surface isn't suitable as a base for resin. Common scenarios include:
- Existing surface is gravel, grass, or bare earth
- Concrete or tarmac is severely cracked, heaved, or unstable
- Drainage is poor and water pools on the surface
- The driveway level needs adjusting for door thresholds or gutters
- There's no existing hard surface at all (new build or garden conversion)
Can You Avoid Groundwork Costs?
If your existing tarmac or concrete is in good condition — level, stable, and free from major cracks — resin can often be applied directly over it. This can save you £1,000–£2,500 on a typical driveway. A professional installer will assess your surface during the site survey and advise whether an overlay is possible.
