It is worth determining the place of the pool near the water supply for the convenience of filling with water. Tape, pegs and cord determine the boundaries of the pool. By the way, now many began to install fabric rollers, they are not very expensive. When developing a pit, you should know that the depth is one and a half meter enough, and the necessary slope of the walls of at least three degrees. A good tamping of the bottom of the pool is 45% of its durability. A layer of sand is followed by at least thirty centimeters and sheathed with wood, tin or plastic formwork. Between the soil and the formwork, pour a concrete solution reinforced with a metal mesh. We align the bottom, observing a small slope for drain, cement with water. By the way, the installation of a drain pipe involves a slope of at least five degrees. The pool is ready!
