Chance Tie Backs

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.

What we do

Chance anchor tieback systemContractors are using the Chance anchor tieback system for these reasons:
  1. Installed anchors can be proof-tested immediately -- no waiting for grout to cure.
  2. Install in almost any weather, with conventional drilling equipment. No concrete trucks or grout pumps required.
  3. Predictable holding strength in all soils.
The success of the screw anchor tieback system is based on decades of similar use of CHANCE 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.

Wall Anchors

Chance anchor tieback systemScrew anchors can help prevent wall movement by holding the wall when soil swells and the resulting pressure pushes against the wall.

Retaining walls can be designed using screw anchors with a modest increase in cost. Proven and building code accepted, these anchors will keep retaining walls from moving.


Helical Anchors

Basement walls can be repaired using helical screw anchors. This is accomplished by drilling a small hole for the anchor rod to pass through the basement wall, and then excavating a hole outside to place the bearing plate. A small high torque motor then rotates the screw anchor system into the soil. Once depth and predetermined torque is achieved, the anchor is terminated and a plate is mounted inside the basement wall to hold the wall in place. If the wall needs to be moved, then sufficient soil must be removed to allow the wall to move.

The CHANCE Screw Anchor saves time, money and is a proven answer to wall retention.
