Hi D_Rail
What you might find is the max. is 80mm and I would think there would be areas with less
Generally this thickness is suitable for Garage hardstands... drive ways should be 100mm with reinforcement mesh
Sorry to say,I would be limiting the driveway to light vehicles only delivery trucks will crack the drive and the mesh will be the only thing holding it together
Did you get any warranty?
Thanks again! It's like my land is vexed with concrete issues. You're right on variability. It ranges from 65mm to 90mm and that's just along the edges! The bill hasn't been paid yet so not sure how it will be resolved - I'm unsure what rights we have but we would have thought we're within our rights to request it be dug up and reinstalled?
