Find out what to ask about cracking, drainage and levels before considering a resin overlay.

An overlay depends on what is already there
An existing driveway is not automatically a suitable foundation just because it looks reasonably flat. Cracks, movement, loose patches and unresolved drainage problems need investigation. Ask whether the base is structurally sound and compatible with the proposed system before comparing overlay prices.
Check the extra height and the drainage route
Adding a new finish changes the surface level. That can affect garage thresholds, door clearance, access covers and the way water moves at the entrance. A permeable resin bound layer on an impermeable base does not automatically create a fully permeable driveway. The installer should explain the drainage arrangement and whether remedial preparation or reconstruction is needed. Keep the quote specific about repairs, cleaning, preparation and exclusions so that “laid over existing” describes a assessed construction choice rather than a shortcut.
Your project checklist
- Point out cracks, movement and puddles during the survey.
- Check finished levels at every threshold and cover.
- Ask why retaining the existing base is appropriate.
Can every concrete or tarmac drive receive resin bound?
No. Compatibility, condition, levels and drainage must be assessed for the actual site and chosen system.
