Helical Tiebacks
Tieback Anchors
Tieback anchors are horizontal elements used to reinforce or “tieback” a retaining wall, basement foundation wall, or earth shoring wall such as sheet piling.
The tieback is drilled or often screwed into the earth where the soils are strong enough to support the wall or foundation that is being anchored. Once the tieback is installed to depth, the anchor is secured to the retaining wall or foundation.
Tieback anchors are installed in segments and can be used at worksites with limited access. There are different types of tiebacks used depending on the soil and rock conditions encountered. The loads or capacity required for the tieback will dictate the anchor’s size that is necessary to complete the project.
Projects That Use Tieback Anchors
Tiebacks are the preferred solution for many engineers to support bowed, leaning, or tilted basement foundations and retaining walls. Slope stabilization and earth retention are additional commercial functions of tiebacks. Tiebacks in conjunction with the shoring or retaining wall are critical components to prevent a wall from overturning and resist the force of the earth being retained.
Other projects that utilize tieback anchors include:
- Seawalls
- Shoring
- Retaining walls
- Sheet Piling and Timber lagging walls
- Seawall
Tieback Products Intech Anchoring Trusts
Intech Anchoring has partnered with and supplies only the best materials available for helical tieback anchoring projects. Intech offers the CHANCE Helical Anchor and Piling System. These products save time and money because of their quick and efficient installation. With Intech’s technical support and training, you can have the confidence that the products we supply will do the job right. Upon installation, tieback anchors can be tested to ensure proper load capacity has been achieved.
CHANCE Helical Anchors
CHANCE Helical Anchors are anchors with helical bearing plates welded to a central steel shaft. Because they are helical, they screw into the soil rather than auger or displace the soil. With each rotation of the helix plate, the anchor is advanced deeper into the soil. CHANCE anchors provide a permanent, cost-effective, and hassle-free solution to bowed, leaning, or rotating foundation walls, retaining walls, steel sheet piling, and many other types of earth retention walls.
CHANCE does not rely on grout during installation, or for capacity of the anchor, meaning engineers can test the system immediately. CHANCE helical anchors can be installed in all weather conditions, with standard installation equipment. Each CHANCE tieback can be custom designed to hold back the required load. The Intech engineering team can assist you with selecting the correct size and length of the anchor for your specific project needs.

Project Highlight
Location – Indiana
Product(s) – CHANCE SS150 Tiebacks
Project Type(s) – Retaining Walls
Sector – Health Care
Intech’s Partner installed 24 SS150 tiebacks for retaining walls. What was originally a hot rush project, ended up getting redesigned several times even after shipping the initial material. Thanks to Intech’s Engineering Team, working with engineers from 3 different companies and bringing them all together on the same page, Intech was able to get a final design and material delivery. Due to Intech’s inventory, we were able to adjust and accommodate bolt-on 14” helices. Intech’s Partner was extremely satisfied with our service.
