Tarmac To Resin Driveway Conversion Questions

Yes, if the tarmac is structurally sound. The surface needs checking for crack depth, soft spots, and drainage before any resin is applied. Where the base passes that check, an overlay avoids a full dig-out.

Not always. If the base is stable and draining correctly, the resin bound finish can go over the existing tarmac. If the inspection finds movement or structural failure, removal is needed and quoted as a separate stage.

They can if left untreated. Cracks and weak areas are filled and remediated before the bonding layer is applied. Skipping that step allows the crack to continue moving and reflect through the resin finish.

A site survey is the only reliable way to check. The specialist looks at crack pattern and depth, sub-base stability, surface softness, and drainage falls. That assessment determines whether an overlay will hold.

A resin bound surface is permeable, so rainwater drains through rather than running off. This satisfies Essex planning guidance on SuDS-compliant surfaces for front driveways over five square metres, meaning no planning permission is typically required.

Cracks widen with freeze-thaw cycles and vehicle loading. Soft spots grow as water gets beneath the surface. The longer the tarmac is left, the more likely the base deteriorates to the point where an overlay is no longer viable and a full dig-out becomes unavoidable.
