Tie-Back Anchors

A pre-engineered tieback system for earth retention supplied by the largest manufacturer of anchors in the world 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 200,000 pounds per anchor are obtainable with this system. Proven on hundreds of applications these cost effective tiebacks can be tested immediately. No concrete to wait for curing! This saves time and money plus improves schedules.

TEAM Foundation Systems Ltd. personnel can show you the advantages on specific applications.
