First complete the steps for your pool kit assembly up to the liner installation step. You may need to install some of the top rails for stability of the pool wall, especially on a windy day. Next use the plastic coping strips to hold the overlap liner in place. The JBD liner has the plastic coping strip made into the liner so you will skip the next step of these instructions for a JBD liner. Use this link for the UBD liner instructions.
Throughout the United States there are different topographies and landscapes. When building an in ground pool an installer must take this into consideration. The different soils can cause for different materials to be used. During excavation there might be water problems wherein the water table is too high. The excavator can stop and dig a small hole and place a sump pump in the hole while getting rid of the problematic water. To protect the liner and also to create a nice smooth bottom the installer will mix a base to go underneath the liner and on top of the soil.
When someone decides to get an in ground pool for their yard, the first thing to decide is what type of pool. You can choose between a gunite, fiberglass, or vinyl liner pool. All three choices come in a variety of shapes and sizes.
