Existing construction
If the current driveway has uneven sections, ask the survey to establish whether the base needs repair or replacement.
Why it matters for your resin driveway: Photograph defects and previous patches so the retained layers and any rebuilding can be discussed separately. For a resin driveway, it can affect preparation, base suitability, drainage, edging and the finished level under vehicle use.
Useful photograph: the whole existing surface plus close views of cracks, movement or patches.
