What is the average cost of a resin driveway in Dorset?
As of 2026, the average cost for a high-quality resin bound driveway in Dorset is between £60 and £90 per square metre. This rate applies to overlaying an existing surface. If full excavation and a new sub-base are required, costs typically range from £120 to £150 per square metre.
2026 Cost Estimates by Driveway Size
To give you a realistic idea of the total investment, here are the estimated costs for typical driveway sizes in the Dorset area.
| Driveway Size | Type of Installation | Estimated Price Range |
| Small (20m²) | Overlay (Existing Base) | £1,200 – £1,800 |
| Small (20m²) | Full Excavation | £2,400 – £3,000 |
| Medium (50m²) | Overlay (Existing Base) | £3,000 – £4,500 |
| Medium (50m²) | Full Excavation | £6,000 – £7,500 |
| Large (100m²) | Overlay (Existing Base) | £6,000 – £9,000 |
| Large (100m²) | Full Excavation | £12,000 – £15,000 |
Note: These prices are estimates. For a precise figure, a site survey is always required.
Understanding the 3 Main Cost Factors
When we prepare a quote at PRO Dorset Resin, we analyse three specific variables. Understanding these will help you see exactly where your money is going.
The Existing Sub-Base (The Foundation)
The most critical factor is what lies beneath. The condition of your current driveway dictates the work required.
- Resin Overlay (Cost-Effective): If you have an existing concrete or tarmac surface that is structurally sound (no cracks or sinking), we can often install the resin layer directly on top. This is the entry-level option, usually sitting at the £60–£80/m² range.
- Full Excavation (Premium): If you have a grass lawn or a damaged driveway, we must excavate the area and install a new permeable Type 3 sub-base and asphalt course. This ensures the driveway won’t sink, but it increases labour and material costs significantly.

The Size of the Area
Economies of scale apply to driveway installations.
- Small Paths (Under 20m²): These often have a higher cost per square metre due to fixed logistical costs—it costs us the same in fuel and crew time to get the mixing trucks to the site, whether the job is small or large.
- Large Driveways (Over 50m²): Larger areas often see the price per metre drop, as the fixed costs are spread over a bigger area.
UV-Stable Resin vs. Non-UV
At PRO Dorset Resin, we prioritise UV-stable aliphatic resin, but it is important to know the difference in market pricing.
- Non-UV Resin: Cheaper upfront, but will yellow and discolour when exposed to sunlight (known as the “bronzing” effect). We rarely recommend this for exterior driveways.
- UV-Stable Resin: Costs slightly more but guarantees the stone colour remains true for the lifespan of the driveway. We consider this essential for protecting your investment in the Dorset sun.
Are There Hidden Costs?
To be fully transparent, here are two often-overlooked factors that can influence the final quote:
- Edging: Resin needs a solid border to cure against. If your driveway doesn’t have existing walls or curbs, we may need to install brick, steel, or stone edging.
- Manhole Covers: We recommend replacing standard covers with “recessed trays.” These allow us to fill the cover with resin, blending it seamlessly into the driveway for a premium look.
Why is a Site Survey Necessary?
Because resin bound surfacing relies on a chemical cure, the ground conditions must be thoroughly checked for moisture and stability. We offer free site surveys across Dorset to assess:
- Drainage requirements (ensuring your driveway remains SUDS compliant).
- Sub-base integrity (checking for hidden cracks).
- Access for machinery.
