I had a builder lay a patio 3x3m last week (Marshalls Argent Smooth slabs). Since then most of the slabs have become noticeably uneven both underfoot and when putting garden furniture out. When he laid the first few they looked a bit wonky but he said they would even out and not be noticeable when joining compound was in between the slabs. He also said that because the slabs were so heavy some had sunk but if they are all the same weight would they not all sink the same amount? He used our old patio slabs crushed up and flattened as the sub base and then laid each slab individually on cement mix. Being smooth granite the slabs are not riven where I would expect some unevenness. Should I ask him to take them up and start again or is it usual to have some some rise and fall? We have already has some to do's with him over other things he has done badly in the garden so don't want anymore unneeded run in's. Thanks for any advice in advance.
