This year I'm planning to finally redo my IG pool that has badly cracked concrete deck. I have a few questions/concerns :
- The huge cracking/shifting most probably came from an unstable base. How can I make sure this never happens again? (concrete or helical pile footings?)
- Would the problem have happened anyways with another type of decking? (I live in Montreal, Canada)
- What is the optimal construction technique for a steel/vinyl pool and decking?
- Is concrete decking required under pavers anyways, to keep it all level?
- Any considerations when choosing the vinyl?
- My main drain seems usesless (poor suction); it goes back to the skimmer. Is this design obsolete now?
- When I bought the pool, one of two return valves was broke and couldn't be repaired without breaking the concrete, so I didn't repair. How could this be avoided this time? Pavers over returns?
- My pump and filter are currently lower than the decking level, under my home's wood deck. Is this good practice?
I basically want a bullet proof pool with a low total lifetime cost, and I'm not very good at maintenance (lack of time).
Thank you for your help!
