Advantages with the use of Lattice Girders

Lattice girders provide the following advantages:

• Immediate roof support over the excavated section.
• Act as a template assuring a minimum thickness when applying shotcrete.
• Become part of the reinforcement in the shotcrete lining.
• Provide support for spilling, if needed, over the next excavation.
• Work equally well with machine mining or drill and shoot tunneling - no need for major investment in special equipment.
• Are practical supports for a wide range of ground conditions.
• Can be erected within a few minutes by a small crew without special handling equipment.
