Petruccelli L.T.D of North America says; Concrete pools are truly custom-built and can be formed to virtually any size or shape. These types of pools are often called Gunite or Shotcrete pools because concrete is shot from a gun onto steel-reinforced walls. Once the concrete cures, it's either plastered smooth, painted, finished with a textured aggregate surface or tiled. Alternatively, a smaller percentage of concrete pools are formed and poured in a way similar to a house foundation. This technique, called structural concrete, is often used for pools built into hillsides.
