Helical Tiebacks: Retaining Wall & Earth Retention Products
Retaining walls, excavation support systems, and earth retention projects depend on anchoring solutions that deliver dependable performance under demanding site conditions. Intech Anchoring Systems supplies helical tiebacks for retaining wall and earth retention applications, supporting contractors, engineers, geotechnical professionals, and project managers with high-quality products, engineering expertise, and project support from planning through installation.
Helical tiebacks offer an efficient alternative to many traditional anchoring methods by delivering immediate load capacity with minimal site disturbance.

Engineered Tieback Systems That Help Keep Projects Moving
Earth retention projects often involve complex soil conditions, restricted access, groundwater concerns, and demanding construction schedules. Selecting the right anchoring system early helps reduce delays while giving contractors greater confidence during installation. Helical tiebacks are frequently specified because they install quickly, can be proof-tested immediately, and eliminate the curing time associated with concrete anchor systems.
Rather than performing installation, Intech Anchoring Systems works alongside your project team by supplying engineered products, technical guidance, equipment options, and application support. This collaborative approach helps engineers and contractors select tieback systems that match project requirements while improving constructability.
Helical Tiebacks from Intech Anchoring Systems
A helical tieback anchor is a segmented deep foundation system with helical bearing plates welded to a central steel shaft. The load is transferred from the shaft to the soil through these bearing plates.
Tieback anchors are installed by rotating the anchors into the ground with rotary drilling equipment. Once the minimum depth is reached, the capacity can be determined by reading the installation torque and correlating it to the holding capacity ratio.
Did You Know?
Our helical tieback system’s capacity can reach up to 55,000 pounds per anchor.
Benefits of Using Helical Anchors
- High production capabilities
- Minimal vibration or displacement of soil during installation
- Instant load capacity
- Installation Torque continuously monitored
- No spoils removal (ideal for contaminated site conditions)
- Easily installed in areas with limited access
Our expert team of geotechnical and structural engineers bring years of experience to provide educated support for your unique job site.
Helical Anchor Installation
A helical anchor is used to resist tensile loading. For these tension-only anchors, square shaft helical anchors are the logical choice. The helical anchor is segmented with helical bearing plates welded to a central steel square shaft.
The load is transferred through the shaft to the soil through the bearing plates. Anchors are coupled together with couplings, and the only limits to installation depth for these anchors are soil conditions such as density. Engineers can achieve whatever depth makes sense economically.
Since the plates are helical, they do not auger but rather screw into the soil with minimal disturbance. Helical bearing plates have a standard 3″ pitch and are spaced at far enough distances that they bear load independently of one another; therefore, the load capacity of one is not influenced by adjacent plates.
Helical Wall Anchoring System
The success of the Helical screw anchors is based on decades of similar use of anchors by electrical utilities. The proven reliability and engineered predictability of the system’s performance give you anchors that are permanent, economical, and hassle free. Engineered for dependability and long-term stability, our Helical Wall Anchor System features exclusive anchoring techniques, tools, designs, and sizes that make other foundation methods a thing of the past. It provides a smart, cost-effective solution for bulging, bowing, or cracked walls.
There is no grout used, so installed anchors can be tested immediately, and concrete trucks or grout pumps are not required. They can be installed in almost any weather using conventional drilling equipment. Anchors from Intech Anchoring Systems have predictable holding strength in all soils. We know because we’ve tested.
The Helical Retaining Wall Anchor System components include Lead Helix, Extension(s), Anchor Termination, and Wall Plate (or C-channel for blocked foundations).
The installation steps include:
- The foundation is prepared for anchor installation by drilling 3″ diameter holes at each anchor location from the inside to the outside.
- After the helical anchor is screwed into the inactive soil, it is then extended through the drilled hole in the wall.
- From the inside, a wall plate (or a steel 6″ C-channel for blocked foundations) is attached to the anchor and tightly secured.

Frequently Asked Questions About Helical Tiebacks
What are helical tiebacks used for?
Helical tiebacks are commonly used to stabilize retaining walls, support excavation shoring systems, reinforce slopes, and provide earth retention for temporary or permanent structures.
Why are helical tiebacks often selected instead of concrete anchors?
They install faster, require no concrete curing time, create minimal site disturbance, and can typically be proof-tested immediately after installation.
Can helical tiebacks be used in restricted-access jobsites?
Yes. Their installation process often requires smaller equipment than traditional anchoring methods, making them well suited for sites with limited access.
How is the capacity of a helical tieback verified?
Installation torque is monitored during installation and correlated to anchor capacity, allowing contractors and engineers to verify performance as the anchor is installed.
Does Intech Anchoring Systems install helical tiebacks?
No. Intech Anchoring Systems supplies helical tieback products, engineering support, equipment solutions, and technical guidance for contractors, engineers, and project teams.
