Shotcrete for Structural Concrete Restoration
Strengthening Parking Structures for the Long Haul
High-velocity concrete application that strengthens structural elements and extends service life in active parking facilities.
What Is Shotcrete and Why Is It Used in Parking Structures
Shotcrete is a method of applying concrete using high-pressure air to spray a mix of cement, aggregates, and water onto a surface. In the context of parking garage rehabilitation, it enables efficient structural repairs in overhead, vertical, or hard-to-access areas without the need for conventional formwork.
By bonding tightly to the existing concrete, shotcrete restores strength and function where deterioration or spalling has occurred. It’s ideal for structural components like beams, walls, columns, or soffits within the garage environment.
When We Use Shotcrete in Garage Repairs
Shotcrete is especially effective when access is limited or where forming and pouring would be impractical. This method offers reliable adhesion, reduced downtime, and adaptability to complex geometries found in multi-level garage structures.
Common applications in parking garage restoration include:
Restoring damaged concrete on overhead or vertical surfaces.
Reinforcing areas with spalled or delaminated concrete.
Repairing structural walls or ceilings where rapid set-up is required.
Performing targeted concrete infill after hydrodemolition.
Performance Benefits of Shotcrete
When structural performance and access limitations intersect, shotcrete is often the most effective solution. While the process varies slightly between wet-mix and dry-mix applications, shotcrete delivers consistently strong results when applied by experienced crews:
Excellent Bond Strength
Creates a strong interface with existing concrete.
Application Flexibility
Ideal for overhead, vertical, and complex surface repairs
Speed of Application
Reduces time on site versus traditional form-and-pour.
Structural Integrity
Restores load-bearing capacity in damaged zones
Why It Works for Parking Garage Restorations
Canmar uses shotcrete as part of its garage rehabilitation toolkit because it provides a reliable solution for structural restoration in demanding site conditions. Our crews are trained in its application and experienced in coordinating this work within active, partially occupied garages, minimizing disruption while reinforcing durability.
Whether repairing the underside of suspended slabs or stabilizing vertical walls within confined areas, shotcrete delivers results without extensive demolition or downtime.
