Expandable Liner Base

How should the bottom be landscaped on a 27' round pool for an expandable liner?


Hi. There are two basic designs for round pool deep ends. One way is to put the deep area off two one side. The page below illustrates a deep end done in this way.

The other way is to dig the deep area out of the center of the pool. With both styles you need to make sure you always have about a foot and a half of walk way before digging the deep area. This means that you start at the sidewall and come in a foot and a half before starting the slope to the deep area.



The slope you put on the deep area is an important consideration. It needs to be sloped, not straight up and down. You need enough of a slope to be able to pack it with sand.

I use a washed mortar sand for all my deep ends. Once the deep area is shaped you should damped the area. You should then wet the sand before spreading it out. Once the sand has been smoothed onto the slopes I wet it down once more before installing the liner.
