I've had these in my garage/office for the past 18 months. Quite happy with them especially for the price but they have warped in places, mainly under my chair and desk and on hot days they expand and bulge. I probably should have left more of a gap round the edges. Will be looking in to replacing with stable mats.
3 packs should do it
wow that's way better value than the Chad Valley offer at Sainsbury.
I am useless at maths. How many packs do I need for 8ft x 8ft. I was thinking of under my grandsons pool.
