Fibreglass pool with concrete piers

Has anyone had experience putting a fibreglass pool in with concrete piers?
We are in Melbourne with a small backyard and bad soil (lots of fill and high water table). We’ve been told by concrete pool builders that we will need extra piers put in but we can’t afford a full concrete pool. Our fibreglass pool installer said we need engineering for concrete piers but they’ve never done an install like that before. Another pool installer told me it’s really difficult / tricky job to put fibreglass on concrete piers. Is it doable?

Hi, Yes I did it back in 2012 with narellan pools. worked perfectly and didnt seem too tricky so I cant understand why they are saying it is difficult.

Ours even had to be retained 1800mm above our courtyard, didnt move at all

You will love a quality fibreglass pool

good luck

Thanks so much for your reply!! Good to know it can be done.

Could be tricky if there is a shallow water table maybe screw piles would be a better option
