A gunite pool is built with a concrete blend that consists of sand, cement, and water. (Shotcrete is a similar blend, but also contains pea gravel.)

Construction crews spray the material through a high-pressure air hose onto a reinforcing network of steel bars to form a thick, rock-hard pool shell. Both gunite and shotcrete pools are engineered concrete creations that provides superb design flexibility and lasting durability.
