My backyard is sloped downward and I'm pouring 3 retaining walls in a U-shape then filling in with dirt to then pour a flat patio with a firepit. I rented a backhoe and I dug out 24 inches below grade on all 3 sides and the highest point of the wall will probably be 4 feet above grade a the bottom that runs parallel with the house and obviously about 2 week below grade. My question to the board is two-fold 1) is that deep enough for the project I'm looking to do? I'm going to backfill with dirt and then use a compactor to flatten. 2) Does anyone know of any good concrete companies that could pour these 3 walls not only correctly, but are reasonably priced?
Thank you in advance.
