DCP-Bolt

Characteristics

The DSI Double Corrosion Protected Bolt (DCP Bolt) is a pre-tensioned & post-grouted rock bolt. It allows for immediate ground support using an expansion shell and has a high density corrugated polyethylene (HDPE) sheath along the bar length that provides long term corrosion protection and load transfer. The system can also be provided with triple corrosion protection (TCP Bolt) using special anti-corrosion bars, galvanizing or epoxy-coating.

• The expansion shell allows for mine heading without immediate grouting
• The DCP bolt’s grooved anchor nut allows for grouting after preloading
• Integrated hex drive nut with grouting channels and domed washer
• Anticorrosion over the full bolt length for long-term protection
