Our pool is old and needs a tremendous amount of work, we also don't use it anymore. We have decided to fill it in and landscape the back yard. I understand there are rules and codes to do this correctly so the pool doesn't pop out of the ground. I am considering doing it myself and want to find out how to go about it. We have alot of 6 inch colored concrete decking around the pool and would like to break it up and use it as part of the fill if possible. Can you advise us on how to fill in a pool.
