Shotcrete

• Shotcrete concrete uses compressed air to shoot concrete onto (or into) a frame or structure.

• Shotcrete is mortar or (usually) concrete conveyed through a hose and pneumatically projected at through a shortcrete nozzle with high velocity onto a surface. Shotcrete undergoes placement and compaction at the same time due to the force with which it is projected from the nozzle.

• It can be impacted onto any type or shape of surface, including vertical or overhead areas.

• Shotcrete is frequently used against vertical soil or rock surfaces, as it eliminates the need for formwork.

• It is sometimes used for rock support, especially in tunneling.

• Shotcrete is also used for applications where seepage is an issue to limit the amount of water entering a construction site due to a high water table or other subterranean sources.

• This type of concrete is often used as a quick fix for weathering for loose soil types in construction zones.
