To learn more about the variety of capabilities TOPCOR Companies has to offer, explore the list below. 


TOPCOR is one of the leading contractors in providing shotcrete services for structural repair applications. We utilize ACI certified (certification process a joint venture between ACI and ASA, American Shotcrete Association) nozzlemen to perform shotcrete repairs. Our experienced crews are led by superintendents who are or have been ACI certified nozzlemen.

Dry Process

Dry Process utilizes pre-blended or damp materials, placed into delivery equipment. Compressed air conveys material through a hose at high velocity to the nozzle, where water is added. At high-impact velocity, material is consolidated onto the receiving surface.

Wet Process

Wet process incorporates all ingredients, including water, and is thoroughly mixed prior to placement into the delivery equipment. Wet material is pumped to the nozzle where compressed air is added to provide high velocity for placement and consolidation of the material onto the receiving surface.

Process Benefits

The Properties of both wet and dry process shotcrete can be further enhanced through the addition of many different additives or admixtures.

Although the hardened properties of shotcrete are similar to conventional cast-in-place concrete, the nature of the shotcrete placement process provides additional benefits, such as excellent bond with most substrates and instant or rapid capabilities, particularly on complex forms or shapes.

Additional Benefits include:

  • Little or no formwork is required
  • Cost effective method for placing concrete
  • Ideal for irregular surface applications
  • Allows for easier material handling in areas with difficult access
