Shotcrete is a method of applying concrete projected at high velocity primarily onto a vertical or overhead surface. The impact created by the application consolidates the concrete. Although the hardened properties of shotcrete are similar to those of conventional cast-in-place concrete, the placement process results in an excellent bond with most substrates and rapid or instant capabilities, particularly on complex forms or shapes. The shotcrete process requires less formwork and can be more economical than conventionally placed concrete. Chickamauga Construction uses the wet-mix process. The wet-mix shotcrete process mixes all ingredients, including water, before introduction into the delivery hose. Shotcrete is used in new construction and repairs and is suitable for curved and thin elements.
