I always thought you needed a minimum 3-6" of base? Feeling a little uneasy now. I specifically avoided other contractors who told me they only install a 2" base . He's been fairly professional and trustworthy so far so I didn't think to scrutinize the work on the day he was installing it until the next day when I noticed the pavers seemed very low relative to my existing wood deck skirting.
Do you think it is possible that it will be fine or am I guaranteed to have a settlement issue in a few years? He has another area to complete later so we can still have a discussion about it... but I imagine he is going to tell me how he installed it is fine and that he will refuse to do any rework.
He installed large format slab pavers if it makes any difference.
