- Shotcrete is the process of depositing the mortar on the prepared surface by jetting it with high pressure applied pneumatically or by spraying.
- In short, it is mortar conveyed through pump applied with high pressure onto a required surface.
- It undergoes placement and compaction at the same time because of the pressure raised from nozzle.
- One can impact it onto any type or shape of surface including vertical or overhead areas.
- It is more economical than the conventional concrete because it requires less formwork.
- It has excellent bonding capacity with a number of materials.

The properties of shotcrete are same as for conventional concrete.But some of the properties are different over the conventional one which are as follows:
- Shotcrete is strong and durable.
- It is resistant to disasters, fires, mold, insects, and vermin.
- It has low permeability.
- One requires less formwork.
- One needs no vibrations for consolidation.
- Cost effective.
Following are the various practical applications:
- Firstly, One uses it in highways and railroad tunnels.
- Used in mining operations.
