Shotcrete and Guniting

Dry-mix shotcrete is a highly efficient and cost-effective way to apply concrete or mortar, for both new construction and repair. Properly applied, it's structurally sound and durable. But it requires specialized knowledge, skill and experience. It's not a job for just any contractor.

Dry-mix shotcrete can be successfully applied on virtually any surface: flat or curved, vertical or sloped, even overhead.

Apollo Industrial Services Division has been successfully applying dry-mix shotcrete since 1995, and this is still the most popular method of application. The setup can be established where access is difficult as equipment can be located up to 1000 feet from the substrate. In most applications this method is more cost effective than wet-mix as it reduces the need for cranes, forms and pumps.


Wet-mix shotcrete involves pumping of a previously prepared concrete, typically ready-mixed concrete, to the nozzle. Compressed air is introduced at the nozzle to impel the mixture onto the receiving surface. The wet-gun procedure generally produces less rebound (waste material that falls to the floor), and dust compared to the dry-mix procedure. The greatest advantage of the wet-mix process is that larger volumes can be placed in less time.

Apollo Industrial Services Division is an experienced applicator of both methods and our projects include but are not limited to:

  • Four Season Hotel Roof Domes (Drymix)
  • Doha North Sewage Pumping Station, PS70 Sump (Wetmix)
  • Doha Zoo, Alligator Pool Area (Drymix)
  • Amonia Storage Tanks, Um Said (Drymix)
  • Doha City Centre Shopping Mall, (Dry Mix)
  • Gas Recycling Project, Dukhan (Drymix)
