1. The angle between the spray head and the rock interface should be kept vertical,In this way, the rebound rate can be minimized.2. The gun face must be kept at 1-1.5 meters from the rock face,Never exceed 1.5 meters, the best distance is 1 meter,Guarantee the minimum rebound rate.3. The amount of
Gunite applicationFor gunite (dry-mix), the builders load the pre-mixed dry material into the hopper of the delivery equipment. They use compressed air to send the material to the nozzle, where it mixes with water. Then it sprays out at super high velocity, which compacts the material on placement.
Concrete pools are often referred to as “gunite” pools, but then what’s shotcrete? Are gunite, shotcrete, and concrete all the same thing? Not to worry… all will be revealed. (Doesn’t that sound ominous? I love it.)Quick refresher: concrete is a mix of water, cement, sand, and a coarse aggregate, wh
Benefits of using the dry-process include:· Easy setup, shutdown and cleanup.· On-site control of materials.· Conveying distances from the gun can be up to 1,000 ft horizontally or 500 feet vertically.· The wet-process includes first thoroughly mixing and introducing all ingredients, including water

What is Shotcrete？
Shotcrete, gunite or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique. It is typically reinforced by conventional steel rods, steel mesh, or fibers.
Shotcrete is usually an all-inclusive term for both the wet-mix and dry-mix versions. In pool construction, however, shotcrete refers to wet mix and gunite to dry mix. In this context, these terms are not interchangeable.
