I have a home in East Austin with a pool first built in 1965. The pool is 5-sided and geometric, about 101' in diameter and 18k gallons.
The last homeowner resurfaced the midcentury gunite pool with fiberglass about 6 years ago. When the last owner had the fiberglass installed, they also had structural cracks in the original pool shell repaired, the plumbing redone, new coping put on, and the tile repaired. In corresponding with the last owner, they had the fiberglass installed because of shifting in the soil and a perpetual need/threat to repair the pool. The soil where I currently live shifts and moves every season. The home I live in had foundation repairs with piers along the slabs and the whole nine yards because that's just what happens in Central Texas.
Currently, the fiberglass is failing and has failed multiple times and is popping off from underneath. The whole deep end is spongy like a trampoline. I have been saving money for some time to have this repaired and have contacted 19 contractors in my area for a remodel and am totally lost.
I am have had 12 contractors come look at the pool, I'm not joking when I say I've got equal advice on four topics:
1. 3 contractors won't touch it because of a combination of the fiberglass and the soil movement
2. 3 contractors say take off the fiberglass, drill hydrostatic holes, fix any structural repairs, and put some kind of bead quartz on it and don't worry about the movement in the soil
3. 3 contractors say call the original fiberglass company and have them come and resurface the pool but no matter what it will need perpetual fixing because fiberglass isn't good no matter which way you slice it
4. 3 contractors say to have a vinyl liner installed as that is the only way to mitigate the movement in the soil, it's what they do in Louisiana and other Southern states
Do any of you live in a clay soil area? Can any of you offer some advice on this decision? I'm terrified I'll make the wrong choice and wind up having to do this all over again in three years.
Thank you so much for reading!
