Shotcrete, or spraying concrete, can be done
with most REED Concrete Pumps and all REED Gunite Machines.
Both shotcrete methods are used on applications such as:
1. Concrete Repair (Bridge Repair, Infrastructure Repair, Etc)
2. Mine Support (sprayed concrete walls and ceilings)
3. Swimming Pool Construction - Sprayed Concrete Shells
4. Tunnel Construction
5. Parking Garage Repair and Concrete Building Repair
6. Retaining Wall Construction
7. Foam Panel Shotcrete Building Systems
8. Refractory Material Spraying - Refractory Lining
9. Skateboard Park Construction
11. Artificial Rock Construction
12. Zoo Construction
13. Slope Stabilization
14. Concrete Dome Construction
With "wet-process shotcrete" a low-slump concrete
mix is pumped with a Concrete
Pump to the end of the pipeline where a special
is attached. That shotcrete nozzle introduces compressed
air to the concrete. This compressed air typically
comes from a 165-185cfm air compressor - sold separately.
The addition of the compressed air adds velocity
to the concrete so it sprays out of the nozzle.
This velocity, combined with the low slump of the
shotcrete mix, allows the concrete to be sprayed
on slopes, vertical walls, and overhead.

known as "dry process shotcrete", uses
a different process than the concrete
pumps listed above. Gunite machines use
air pressure to convey dry material from the machine through the hose
to the nozzle where water is added.
