# Can Resin Be Laid Over an Existing Driveway?

One of the most effective ways to reduce the cost of a new resin driveway is to avoid excavation by overlaying the existing surface. But this isn't always possible. Here's when it works and when it doesn't.

## Overlaying Tarmac

Tarmac is one of the best surfaces for a resin overlay. If your existing tarmac is stable, reasonably level, and free from significant cracks or potholes, resin bound can be applied directly on top. This can save you [£25–£50 per m² in groundwork costs](/driveway-groundwork-cost-uk).

The tarmac must be clean and dry. Any loose areas or major cracks should be repaired before the resin is applied. Most installers will assess the suitability during a site survey.

## Overlaying Concrete

Concrete is an excellent base for resin bound, provided it's in good condition. Check for rising damp, major cracks, and stability. Small hairline cracks are usually acceptable, but anything wider than 3–5mm should be repaired first.

## When Excavation Is Needed

You'll need full excavation and a new sub-base if:

-   The existing surface is unstable, heaved, or badly cracked
-   There are drainage problems or standing water
-   The surface level needs adjusting for door thresholds
-   The existing surface is gravel, grass, or bare earth
-   Block paving has shifted significantly

The best way to find out whether your existing driveway is suitable for an overlay is to request a professional site survey. Use our [cost calculator](/resin-driveway-calculator) for an estimate with and without groundwork.
