Learn / Gunite & shotcrete
Shotcrete is concrete or mortar placed pneumatically. Gunite is the commonly used name for the dry-mix process. Both dry-mix and wet-mix are forms of shotcrete.
Dry-mix process
Dry ingredients are carried through a hose by compressed air. Water is added at the nozzle before the material reaches the prepared surface.
The process is often used for repairs and work involving frequent starts, stops, or relocation.
See our foundation applications →Wet-mix process
Concrete is mixed with water before entering the pump. Compressed air at the nozzle helps project the material onto the surface.
The process is often selected for continuous placement and larger production requirements.
Discuss a commercial application →The process is only part of the repair
Either method needs an appropriate mix, sound surface preparation, suitable equipment, skilled application, and curing. Reinforcement, anchorage, and thickness follow the project requirements.
The name of the process alone is not a guarantee of strength, waterproofing, or structural suitability. The condition of the existing structure and the repair design come first.
Tell us the structure, repair area, material, access, and expected production. We will discuss the application rather than recommend one method for every job.
