Shotcrete is a method of applying concrete projected at high velocity primarily on to a vertical or overhead surface. The impact created by the application consolidates the concrete. The shotcrete process requires less formwork and can be more economical than conventionally placed concrete. Shotcrete is applied using a wet- or dry-mix process.
Gunite is made of sand, water, and cement, and is applied in layers using a specialized spray gun. Gunite swimming pools are popular for their versatility in shape, as well as their durability. Because of this, gunite is the most common pool type seen at many resorts, and now, homes.
