What is the proper material to use when back filling a semi inground pool? The pool will be about 26" deep. 16'x24' oval with a deck half way around. One installer wants to use all sand with some river rock ontop to finish it, the other installer just wants to use the excavated dirt. The over dig around the pool will be about 24" wide x 26" deep. It is a clay/sand mixture.
Ready to get this going
