Help pool liner install

[Ed Kaz]

I am trying to install a expandable pool liner in my 24' pool. The kids would like a deeper pool and since I am replacing the liner anyway ...The question I have is what can I place under the liner where the slope for the deep part goes? I had looked at the geotextile(I think thats the way it's spelled),but I do not think it will lay flat and cause wrinkles. Should I just use sand again? The reason I would like the liner underlament is to pervent roots and grass (have big tree near pool).

Thanks for any help Ed

I think you need to use sand. I bet if I'm wrong, someone will surely correct me.

It's been many years since I did that but I didn't use anything.

My old liner rotted just above the water line due to the sun. So I cut the old liner to make an apron all around the pool to cover the new liner. That worked quite well.

our 24-ft diameter x 4' deep round pool is above ground with a flat bottom and sand under liner.

not sure about your description, but here's a google search:

Ed, it looks like the geotextile should work see:

BUT......be advised....nature works in mysterious ways.
