I’m confused... if they built the area up, what is the retaining wall for? To keep weight of pool from displacing the dirt it is sitting on?I decided to do option 1 but the guys kind of messed me up a little. They leveled out the area but they dug out the grass but built it up instead of down!! Now I have to get a retaining wall in and the cheapest option is to use lumber vs cinderblocks but the lumber will last probably 10 years he says.. either way I'm not happy about that and I will negotiate the price down if possible. They are coming back in 2 days to put in the retaining wall. I'll add pictures then. Thanks everyone for your suggestions
I would insist that they do what you originally asked them to do.
