What is the meaning of shotcreting?

Shotcreting is a construction technique that involves the application of concrete or mortar through a hose and pneumatically projecting it at high velocity onto a surface, such as a wall or a slope. This method is often used for reinforcing structures, such as tunnels, Swimming Pools, and retaining walls, due to its ability to adhere to irregular surfaces and provide a strong, durable finish. Shotcrete can be applied in a dry or wet mix form, depending on the specific requirements of the project.
