Shotcrete Innovation at Charlotte Airport: Speed, Strength, and Savings
As infrastructure demands grow, forward-thinking engineers are turning to shotcrete for its performance, flexibility, and visual impact. The Charlotte Airport North End Around Taxiway project is a prime example of how structural and architectural shotcrete can outperform traditional concrete systems.
Reengineering for Efficiency
Originally specified with a cast-in-place facing system, the project’s retaining wall design was value engineered to utilize sculpted shotcrete instead. Boulderscape collaborated with project stakeholders to optimize both performance and aesthetics without compromising structural integrity.
Key Project Details
- 8,350 sq. ft. of soil nail shoring
- 8″ thick structural shotcrete with a 5,000 PSI mix
- 2″ thick architectural shotcrete overlay
- Charlotte Ashlar finish in Gray Speckle color scheme
- Completed in a record 8-day installation timeframe
- Delivered an average of 34% savings over traditional wall finishes
Why Shotcrete Was the Smarter Choice
Choosing shotcrete enabled faster installation, fewer construction delays, and a more refined final appearance. The hydration-stabilized 5,000 PSI mix allowed placement in variable weather conditions, while still achieving optimal bonding, strength, and finish quality.
Aesthetic Precision with Structural Integrity
The use of sculpted shotcrete allowed Boulderscape’s finish team to apply the Charlotte Ashlar texture seamlessly across the wall surface. Unlike cast-in-place concrete, shotcrete made it possible to create a consistent, high-relief finish that visually enhances the surrounding airport landscape.
Benefits Beyond Cost and Time
Beyond savings and speed, shotcrete offers long-term durability and versatility. Boulderscape’s approach ensures:
- Fewer joints and form lines
- Reduced construction waste
- Superior weather adaptability
- Design flexibility for custom finishes
Conclusion: Shotcrete as a Modern Infrastructure Standard
The Charlotte Airport project underscores the evolving role of shotcrete in civil infrastructure. Its structural strength, fast turnaround, and ability to deliver architectural finishes make it a premier solution for projects demanding both performance and visual appeal.
With over three decades of experience, Boulderscape continues to lead the way in redefining how shotcrete is used on high-profile public works.
