Hi everyone, great forum with, wow, lots of info. Been reading for months trying to piece together what I want. However my situation is very unique, at least it seems to be. I have talked to several PBs and have not found anyone really interested in tackling the job.
So, I live in Biloxi, MS in a waterfront home, a home that had serious flood damage in Katrina and had 2' of water in our basement in Aug from Isaac. I know I can't build the pool high enough to avoid all flooding like we saw with Katrina but I do want to build it high enough to defeat the every couple year flooding like we saw with Isaac. So I'm looking to build the pool within a retaining wall. Pool depth not to exceed 5'.
What I want to do is install a pool basically on top of the undisturbed ground just removing the upper part of the slope as needed, next build a retaining wall around it, then install a french drainage system within, and finish up by backfilling with clean crushed gravel compacted in lifts. Of course after that I would have a deck poured. My thought is flood water could enter and exit the cavity without the backfill getting sucked out.
I'm open to vinyl, fiberglass, or gunite/shocrete but we really like gunite.
So my questions are:
1. Does my gravel backfilled retaining wall concept sound feasible? Suggestions...
2. Which type of pool would install and work best in a wall as described?
3. If I build the pool lower, no wall, and it did flood, what kind of problems could I expect? Just cleanup? Which type of pool would do best?
4. Will a flooded pool pop out of the ground? Liner float up?
Here a few photos of my home and the pool design with wall that I'm thinking of. Thanks for any help.
