What is Shotcrete?
Shotcrete is a method of applying concrete by spraying it at high velocity onto a surface. It is used for tunnel linings, retaining walls, and slope stabilization. The process can be dry-mix or wet-mix, depending on how water is added. Shotcrete offers high strength, low permeability, and rapid application.
History of Shotcrete
This technology was originally invented in 1907 by an American taxidermist named Carl Akeley. He used a dry-mix process until the 1950s, when a better wet-mix process was introduced.
Gunite vs. Shotcrete
Gunite is a term that refers to only the dry-mix application process. Shotcrete is an all-inclusive term that can be used to refer to both the dry-mix and wet-mix processes.
Applications of Shotcrete
Shotcrete is widely used in tunnel linings, canals, slope stabilization, swimming pools, skate parks, and structural repairs. Its ability to adhere to various surfaces and shapes makes it ideal for complex structural support needs.
Advantages of Shotcrete
Shotcrete offers rapid application, excellent bonding to surfaces, versatility in construction projects, reduced formwork needs, and the ability to apply on complex shapes and in tight spaces, enhancing structural integrity and durability.
