Have a 14x42 Intex ultra frame pool currently. Looking to get a larger pool possibly an 18 or 20 ft pool. Ground will neeve to be excavated out more than the current 15 ft and leveled. From what Ive read this type of pool cannot have sand used to level it. Is anyone familiar with this type of pool? Also having difficulty locating person to do the job..pool companies only want to install pool and idk if excavation company would just want to do like a normal above ground pool.
