Heads-up: Your widest run is 5.0 m — rolls are 4 m wide, so you'll have a seam. Plan it where foot traffic crosses the seam, not along it, and use joining tape + adhesive — not just pins. Why it matters: Sand infill (kiln-dried) is mandatory for pets, kids and high-traffic — without it the pile flattens within months and the grass slides on the base.
