ABSTRACT:
A method of constructing a swimming pool which includes the steps of forming an excavation of desired size and shape in the ground, the excavation including a footing area, placing polyethylene film over the footing area and a portion of the remaining excavation surface, setting a wall member on the footing area, pouring a concrete footing on the footing area to embed a portion of the wall, applying a groove-forming device to the wall, pouring additional concrete to form the pool bottom, removing the groove-forming device to expose a groove, and filling the groove with caulking material. An alternative method of forming the pool bottom includes the steps of spraying layers of polyurethane foam on the excavation to form the pool bottom.
