Rainwater and drainage
If the current surface holds puddles, record their location and investigate levels and drainage before selecting a finish.
Why it matters for your resin driveway: Show the direction of falls, where water gathers and every visible channel, gully or discharge point. For a resin driveway, it can affect preparation, base suitability, drainage, edging and the finished level under vehicle use.
