I'm working on plans for our in-ground pool install, and I've already determined I am not going to backfill with dirt like is common around here. I want to do structural backfill to prevent settling in the future, and to allow us to have the concrete apron poured without waiting for it to settle. I haven't seen anything definitive on the best material for backfill. The concrete guy I've been talking to suggested something like #2 crushed stone would be good because it is self-compacting, and it's good for drainage, so I wouldn't have water sitting around by the pool walls. That made sense to me. However, my pool installer says that runner crush is better because it has poor drainage, and would act as a barrier preventing ground water from getting around and then underneath the pool, which could potentially cause the liner to float. Of course runner crush is cheaper, but the labor is much more expensive since you have to compact it every foot or so. Which is the right way to go? Or would either be pretty much fine?
Might be worth noting that the ground in my area is like clay, and the spot the pool is going in can be somewhat wet in the spring months.
