Expandable liners are only made in the overlap style because the amount of overlap will vary depending on the depth you have dug down. It’s pretty much the same as a normal overlap liner except it has a higher wall section. The wall portion’s height will vary according to how much deeper the hole is than that of a normal flat bottom pool.

Due to the imprecise way the liner is placed into the swimming pool (differing amounts will overlap the walls and need to be trimmed after installation), it is not possible to buy a beaded expandable liner. This is because beaded  liners have to be attached precisely at the top of the pool wall. This means you can’t have an expandable pool liner with a top tile or top print pattern but must choose a solid color or full pattern. For full article and installation instructions, click link.
