Shotcrete Technologies Shot Tech Robotic Arms, Supplies and Expertise
Today, mining companies, contractors and engineers have come to rely on the quick, effective method of pneumatically applied concrete known worldwide as shotcrete. It is a key component of many civil and mining projects. Smart contractors know that if shotcrete is applied correctly using the right equipment, additives and technical support, a solid foundation is built for a successful project. That is why it is so vital to work with a knowledgeable, experienced shotcrete partner.
Shotcrete Technologies has been providing quality products and services to the industry since 1979. The leader in shotcreting for underground projects, infrastructures and new construction, Shotcrete Technologies has a clear advantage over competitors. Shotcrete is all we do. While other companies sell all types of concrete additives and equipment, only Shotcrete Technologies maintains a singular focus on shotcreting products and services.
Our service starts long before the spraying begins. Expect our professionals to be involved from start to finish to ensure you receive the most efficient and cost-effective shotcreting. Our teams have worked all over the world on projects including:
- Trasvases Manabi Water Project, Ecuador
- The Red-Line Hollywood Station, Los Angeles, California
- San Roque, Philippines
- Gold Mines, Elko, Nevada
- Tren Urbano, Puerto Rico
- Asian and African Parks, Disney World
- Mission Valley Transit, San Diego, California
- Wine Caves, California
Our process-oriented approach includes working with the top people in the industry on project specification, mix design and material-handling logistics.
Shot-Tech robotic arms and nozzles
As an innovative leader in the industry, Shotcrete Technologies offers you a line of quality products, including:
- Shot-Tech robotic arm – this innovative, remote-controlled spraying arm may be used in tunneling, underground and other applications, and may be mounted on many different carriers. It enables shotcrete to be sprayed immediately after blasting, allowing the nozzleman to do a safer, better job
- Shot-Tech nozzle assembly – our nozzle assembly, used with both hand-held and robotic shotcreting, uses a ‘Venturi’ action, as swirling air surrounds the concrete as it travels through the nozzle. This prevents the concrete from segregating and enables you to shoot from greater distances
Shotcrete equipment and accessories
Because every Shotcrete application is different, STI has the ability to “mix and match” your concrete delivery system from batch plants to pumps and auxiliary equipment.
- Mobile batch plants (between 3cy/hour – 15 cy/hour)
- Various carriers; including telehandlers, tractors, etc
- Accelerator pumps and hoses
- Shotcrete hoses, clamps, couplings and reducers, and nozzles
- Shotcrete/concrete pumps
- Training and technical support are also a large part of our Shotcrete arsenal
The Shot-Set 250 Liquid Accelerator is a liquid, non-caustic accelerator that has a proven track record. With dosages of 2% – 5% by the weight of cement, the Shot-Set 250 Liquid Accelerator lowers rebound to 10% or less – even overhead – and allows the nozzleman to place thicker layers.It provides extreme workability. When your shotcreting project calls for super adhesion and high “first-pass” thicknesses, ST-ALKALI FREE is the one. This homogenous liquid accelerator blends easily and completely.
Shaftlining and culvert lining technologies
Shotcrete Technologies has developed a system for lining/repairing all types of culverts, pipes, shafts and tunnels that is quick, non-disruptive (i.e. no excavation), efficient and at a lower cost than conventional techniques.
The system constructs a new permanent ‘in-situ’ lining using a cementitious mix that will develop a compressive strength of 6000 PSI or greater in seven days. The resulting lining will be more acid and abrasion resistant and more impermeable than ordinary concrete.
Essentially, the process relines sections of a pipe or tunnel with a proprietary shotcrete mix using a ‘spinner’ nozzle that uniformly sprays the material onto the surface. A crew of three can do up to 500ft a day in normal circumstances.

Centrifugal Shaft Mining
Conventional dry-mix shotcrete (where water is added at the nozzle) or wet-mix shotcrete (where air is added at the nozzle to pneumatically convey the material to the receiving surface) has long been used for lining horizontal pipes, culverts, and vertical shafts.
