What is Shotcrete?

Shotcrete is a process of applying spray concrete projected at high-impact velocity onto a receiving surface. The shotcrete process requires less formwork and can be more economical than conventional cast-in-place concrete. Shotcrete, or pneumatically placed concrete, is used in new construction and repairs and is suitable for restricted space, difficult-to-reach areas, and complex shapes.


Gunite is the dry-mix only process in which pre-blended materials are placed into the hopper and compressed air conveys the material through the hose to the nozzle, where the nozzleman controls the addition of water immediately prior to application. Mixing is consolidated as the material touches the receiving surface by the high-impact velocity, through manipulation of the nozzle by a very skilled nozzleman. Shotcrete refers to the dry-mix process and the wet-mix process in which a previously prepared mixture, typically ready-mixed concrete, is pumped to the nozzle. Compressed air is then introduced at the nozzle to propel the mixture onto the receiving surface. The dry mixture of gunite uses relatively larger aggregate, while the wet mixture of shotcrete usually contains smaller aggregate.


Shotcrete has high compressive strength, low permeability, and high durability. It creates an excellent bond with most substrates and flexible placement, particularly on complex forms or shapes. Shotcrete also has the ability to access restricted space and difficult-to-reach areas, including overhead and underground. Shotcrete has the adaptability to repair surfaces that are not cost-effective with other processes and the speed of application reduces labor costs and eliminates downtime. It can also reduce or eliminate crane time and reduces the time and cost associated with formwork.


The Construction Specifications Institute is the organization that publishes the MasterFormat. This publication is the specifications-writing standard for most of today's construction and commercial building design projects in North America. Certification Programs include:

  • 03 37 00 Specialty Placed Concrete

  • 03 37 13 Shotcrete

  • 03 37 16 Pumped Concrete

  • 03 37 19 Pneumatically Placed Concrete

  • 03 37 26 Underwater Placed Concrete

Shotcrete Uses


Shotcrete is highly durable and watertight which makes for a perfect pool shell. The flexible placement of underwater placed concrete, or shotcrete, allows every pool to have a unique shape.


Shotcrete knows no bounds. Design your custom creation free of the constructability limitations and costliness of cast-in-place concrete. Shotcrete is ideal for retaining walls. With its high compressive strength, using shotcrete for the construction or repair of structural shotcrete walls eliminates crane time and reduces costs associated with formwork and labor.


Shotcrete offers slope protection. Structural shotcrete is applied to rock slopes to protect a surface that, if left untreated, would slide or fail. Because shotcrete is pneumatically applied concrete, the material is consolidated against the receiving surface to fill cracks and prevent loose material from falling. Soil Nailing is an engineered method used to stabilize existing slopes and to construct or repair retaining walls from the top down. Soil nails are reinforced bars installed in soil mass and are followed by the application of structural shotcrete walls.


Shotcrete provides a quick and cost-effective means of channel construction, as it provides the ability to access restricted space and difficult-to-reach areas, including overhead and underground.
