• Wet-mix shotcrete tunnel lining
• Underground metro and rail tunnels
• Slope protection shotcrete
• Cavern and shaft lining
• Shotcrete where worker safety is a priority

Advantages

• Alkali-free — significantly safer for workers vs conventional accelerators
• Reduced rebound loss — more economical
• Better long-term strength retention vs alkali accelerators
• Low dust and spray irritation risk
• High early strength development
