Five Star Structural Concrete Gunite – High-Performance Dry Process Shotcrete Repair
Five Star Structural Concrete Gunite is a high-strength, dry-process shotcrete repair mortar designed for rapid and permanent structural concrete repairs. Engineered for superior adhesion, it provides excellent freeze/thaw resistance, sulfate resistance, and corrosion protection. With high early strength development and the ability to be coated in as little as 8 to 24 hours, it is ideal for industrial shutdown repairs, vertical and overhead applications, marine structures, and load-bearing concrete rehabilitation. The single-component formulation ensures consistent application and long-term durability in demanding environments.
Key Features:
- High early and ultimate compressive strengths
- Single-component, dry-process shotcrete formula
- Excellent freeze/thaw and sulfate resistance
- Superior adhesion for structural integrity
- Minimal rebound for efficient application
- Can be coated within 8 to 24 hours
- Designed for vertical and overhead repairs
- Corrosion-resistant with very low chloride ion permeability
