A pre-engineered tieback system for earth retention simplifies the challenges for contractors. These tieback anchors are installed by rotating the anchors into the ground with common rotary drilling equipment.
Once the minimum depth is obtained the capacity can be determined by reading the installing torque and correlating it to the holding capacity ratio.
Capacities to 110,000 pounds per anchor are obtainable with this system. Proven on hundreds of applications, these cost effective tiebacks can be tested immediately. There is no need to wait for concrete to cure! This saves time and money as well as improves schedules.
Advantages for our tieback system include:
Installed anchors can be proof-tested immediately -- no waiting for grout to cure.
Anchors can be installed in almost any weather, with conventional drilling equipment.
No concrete trucks or grout pumps are required.
Predictable holding strength in all soils.
The success of the helical tieback system is based on decades of similar use of anchors by electric utilities.
The proven reliability and engineered predictability of the system's performance give you tiebacks that are positive, economical, and hassle-free.
