Shotcrete is a method of applying concrete by high velocity projection primarily on to a vertical or overhead surface. The impact created by the application consolidates the concrete and eliminates the use of formwork for a quicker turnaround.

Certified Excellence

Benefit from the expertise of Dumoulin & Associates: our applicators are certified by the American Concrete Institute (ACI).

Processes followed

We offer you two methods of shotcrete application:

  • The dry process: the most common way to undertake repairs. The dry ingredients are mixed directly, in a hose, with the water in the spray. A perforated ring in the hose allow the ingredients to mix.
  • The wet process: normally involves conventionally prepared concrete or mortar and requires a concrete pump and compressor.

Shotcrete uses

  • Concrete structural repairs, such as bridges, viaducts, dams, reservoirs, train or metro tunnels, marine structures and multi-level parking garages
  • Repair and covering of sewer pipes, storm sewers and sanitary sewers
  • New constructions: slope stabilization, soil nailing, covering the walls of tunnels, pools and all other concrete constructions
