Rainwater and drainage
If the drive slopes towards the street or building, measure falls and include the drainage detail in the quote.
Why it matters for your resin patio: Show the direction of falls, where water gathers and every visible channel, gully or discharge point. For a resin patio, it can affect pedestrian comfort, door connections, furniture space, drainage, edging and installation access.
