CHANCE® helical tiebacks are a pre-engineered mechanical anchoring system for permanent and temporary shoring. The success of the helical anchor tieback system is based on decades of similar use of CHANCE anchors in the electric utility industry. Capacities up to 200,000 pounds per anchor are obtainable with this “instant” tieback shoring method. CHANCE tiebacks offer a fast, cost-effective and simple solution for any tieback project.
Let’s do a comparison of the three main advantages of CHANCE tiebacks versus the conventional grouted tendon methods:
In addition to these main points, other items that give helical tiebacks an edge over grouted tendons is there is no need for dewatering for below water table applications. Helical piles can be installed with smaller equipment - even with the same equipment that would be used for a grouted tendon. Additionally, no casing or grouted sock is needed when working on non-cohesive soils, and no concrete or grout pump is required.
Remember that the use of cement itself is extremely hard on the environment. The cement industry is one of the largest contributors to greenhouse gases on the planet. As the world shifts to eco-friendly construction solutions, a tieback system that will not involve the use of grout is a win-win for everyone. Read more about sustainability with helical piles.
