Possible to dig out old swimming pool and put in a new one? (conversion, build)

[cityflair]

We like a house that previously had a pool that was filled in. We want a pool. I can see the exact outline of the old one. They drilled holes in it, put in pea gravel, then dirt, then mulch. The concrete surround is still in decent shape. I heard of someone else's project; digging out some of the dirt and inserting a formed fiberglass pool. Is this possible? Cost? Thanks!

"you might get away with it..."
but have enough budget ready to do it right before you start.

right = completely starting over with an empty hole in the ground.
budget = cost to demo and haul off all that is there PLUS the cost to build a new in ground pool.

is it a fiberglass or vinyl liner pool? All of the old concrete deck would need to be broken out and if it is a concrete pool, the pool would need to be broken out. i wouldnt recommend putting another vinyl liner or concrete/gunite pool as you wont have solid virgin ground to work with unless you made it much larger and deeper. you can however drop in a fiberglass pool which only requires pea gravel to set in or washed sand both of which are 100% compactable. It's completely doable but expect to pay 30-40k. Ive done it several times as i worked for a pool company for 5 years. You wont be able to reuse the concrete deck that was around the pool or be able to form fit it inside of the pool but you can putt in a fiberglass of any size or shape you want provided you remove all of the old pool and fill the voids with pea gravel.

I got some more information... The company we are going to use has already done a similar installation in this area and the homeowners are pleased with the results. They cleaned it out and put in a vinyl liner. I am hoping to visit this pool. The poolman is going to check out the site soon. Thanks for your comments!

ive done a few conversions to concrete pools with a rubberized pvc liner but never vinyl liner straight to concrete. i would think that would wear through the liner pretty quickly. good luck though, hopefully they didnt fill the pool in because it cracked or floated out of the ground when draining it.
