Retaining wall question

[babzog]

Scratch my last post... called the pool company today and they said no backfill on the pool.

Not even on the bottom plates and rail - all must be exposed otherwise the warranty would be void. Well, if there were a warranty on it, it would be void. Since it's a used pool and has been moved, much of the original warranty is moot. Still, I want to construct this thing properly, so I'm thinking of sticking with the wall, though I'm still on the fence.

If I went with backfilling, am I okay to do so in a heavy frost area or is this one of the reasons why I shouldn't? The lady at the pool co. said that the backfill would prevent the pool from moving properly during a frost heave. Anyone here have experience with a backfilled pool in a frost area?

If I went with the wall, how then, would I construct the drain in the space (2') between the retaining wall and pool wall? If I dig down too close to the pool wall, would I compromise the soil's strength, leading to a potential collapse?

Anyone have pics of such a drain?
