Steel that reaches past the problem and holds on.
Helical tie-back anchors screw into the dense soil behind your seawall and tie the wall to it, with every anchor proving its capacity as it goes in.
Let's take the first step toward solid ground.
A local specialist will evaluate your foundation, walk you through the findings, and send a clear estimate. No cost, no pressure.
What to know about helical tie-back anchors, and when it's the right call.
Think of a helical tie-back as a giant screw set sideways into the hillside of soil behind your seawall. The helix plates pull the shaft through the weak, water loaded soil near the wall and into the competent ground beyond it, and the installation torque is the honest broker: soil strength shows up directly as resistance, so capacity is measured during installation rather than assumed afterward. Once the target torque is reached, a marine grade anchor plate connects the shaft to the wall face and the assembly is tensioned. From that moment the wall is no longer resisting the soil pressure alone; the load travels through the anchor into ground that is not going anywhere. Multiple anchors spread the restraint across the wall so pressure cannot concentrate at one weak point, and because the system does not rely on the wall's own deteriorating materials for strength, it works even on aging walls whose original tie rods have failed. Tiebacks hold a wall that is worth holding, which is why the sequence around them matters. Ground that has been washing out gets stabilized first with void filling marine foam, and the whole system starts from a written condition assessment that measures the lean, maps the soil loss, and names what is pushing. The service overview lives on our anchoring page.
The symptoms that usually lead to helical tie-back anchors are on the seawall repair problem signs page, alongside the other signs that point to the same underlying cause.
How we install helical tie-back anchors.
Free evaluation and anchor plan
A specialist measures the wall's movement, assesses the soil and the old anchor rods, and specifies anchor count, spacing, and target capacities in writing.
Prepare the wall connections
Connection points are prepared on the wall face as part of our seawall anchoring service, sized for marine grade hardware.
Drive each anchor to verified torque
Hydraulic drive equipment rotates each helical anchor through the weak soil into dense ground, and driving continues until the torque reading proves the required capacity.
Connect and tension
Each anchor is fastened to the wall with marine grade plates and tensioned, drawing a leaning wall back toward plumb where it is safe to do so.
Verify and finish
The wall's position is checked against the starting measurements, connections are sealed against corrosion that ages exposed steel, and the site is cleaned.
Care and expertise from a team that's been doing this since 2011.
When the fix is helical tie-back anchors, the installer matters as much as the method. Dalinghaus crews handle seawall repair and related structural work in coastal California, and nothing else.
Foundation repair, concrete leveling, and crawl space repair are our entire focus. Not a sideline.
More than 2,000 projects on the clay and desert soils of California, Arizona, and Nevada since 2011.
CSLB License #983851 in California, ROC #330307 in Arizona, and License #0089738 in Nevada. Look us up with the state before we ever set foot on your property.
Warranty terms come in writing with every proposal, and the terms that apply to your job are stated in that job's paperwork. Ask your project specialist during the free evaluation.

A steel shaft with screw shaped plates that is driven at an angle into the stable soil behind a wall, then connected to the wall face and tensioned. It gives the wall a mechanical hold on ground beyond the soil that is pushing it, restoring the lateral restraint the wall has lost.
