A smooth top does not prove a sound base
Cracks, sunken wheel tracks and soft edges can point to problems below the visible surface. Covering those symptoms may improve appearance temporarily without correcting their cause. During a Horsham site survey, ask the contractor to explain whether the existing construction can be retained or needs rebuilding.

The specification should address excavation where needed, the supporting layers, edge restraints and the finished levels. Vehicle loads and access arrangements influence the design; do not assume every domestic driveway can use an identical build-up. Ask how water will be kept away from the garage and where any drainage channel discharges. A continuous tarmac finish still needs a water-management plan. Before accepting a quote, make sure preparation and surfacing are priced together, with exclusions clearly stated rather than hidden behind a low resurfacing figure.
Your project checklist
- Show the installer existing cracks and settlement.
- Confirm driveway levels at doors and pavements.
- Request written preparation and drainage details.
Is resurfacing always cheaper than replacement?
It may involve less work, but it is suitable only where the existing structure and levels support the proposed finish.
