Sand Under Existing Liner

I just removed my old liner to replace it. The center of the ground is much lower than the rest of the pool. Can I just use sand to raise that up? The ground is already sand. What is that best technique for leveling the sand?

Hi Rob

Sand is fine for raising an area a couple of inches. Any more than that I would use dirt with sand over it.

I use the back side of a rake to do the first smoothing of the sand. I follow that up with a soft push broom. The broom makes the sand very smooth. The sand can then be watered and packed, and then broomed again just before the liner installation.
