Thank you for your response. That's how I feel about it, too. I think it should be filled in. Even if it doesn't need to be done, just for peace of mind, it will be worth it.

Hello, I'm looking for some advice on a project I'd like to hire someone to undertake. We have an ingound, indoor pool that we don't use often. We'd like to turn the room into a rec room that could be used year round. Obviously, we'll need a floor over it. I've spoken to one builder already, and have others lined up to come over and check it out too. The liner is shot, btw. The first builder had an interesting solution to the problem, but said we didn't need to fill in the pool with anything. (He wants to cut into the concrete about 6" and lay galvanized steel flooring across it, and then pour concrete on top to make it level with the existing concrete floor.) I'm worried that if I don't fill in the pool with any type of fill, the dirt/sand will slide due to the water table moving it. Any ideas? Should I fill it in, at least part way to keep the dirt/sand from moving? The pool is 14,000 gallons and would take a tremendous amount of fill to fill it all the way up. (Not to mention the task of getting the fill from the truck to inside the building...) SO, what do you think? Fill it in all the way, part way, or none of the way? Thank you all for your help and advice.
