A Low-Profile Solution for Stabilizing Bowed Foundation Walls

In many cases, traditional wall anchors provide reliable support, but not every property has the space required for exterior anchor installation. That’s where helical tie-back systems come in. At Anchored Walls, we offer helical tie-backs as a proven solution for stabilizing bowed or leaning basement walls, especially on properties with limited access.

Repair options for your home.

What Are Helical Tie-Backs?

Helical tie-backs are long, steel shafts with screw-like helices that are drilled diagonally through the foundation wall and into dense, load-bearing soil. Once installed to the proper depth and torque, these anchors provide permanent lateral resistance against outside soil pressure. They’re mounted to the interior wall with a steel bracket and can be tensioned to restore and stabilize the wall’s position.This system is ideal for homeowners who need strong, low-profile wall reinforcement without disturbing exterior landscaping or hardscaping.

When Helical Tie-Backs Are the Right Choice

Not all foundation problems can be solved with the same tool. Helical tie-backs are often the best option in situations like: Limited yard space or adjacent property lines Concrete patios, driveways, or additions that prevent excavation Reinforced concrete or block walls requiring deeper anchoring Tight access conditions where traditional anchors can’t be used Our team will evaluate your home’s layout, soil conditions, and wall structure before recommending the right system. In some cases, helical tie-backs can be used alongside other solutions for comprehensive wall repair.

How the Installation Works

Installing helical tie-backs begins with a detailed inspection to determine anchor placement and torque requirements. Our team then drills the tie-backs through the foundation wall at an engineered angle and depth, anchoring them securely into stable soil beyond the zone of pressure.Once installed, each tie-back is connected to an interior bracket and carefully tensioned. The result is immediate resistance against soil pressure and long-term protection from further inward movement. In many cases, we’re able to straighten the wall as part of the process.Unlike temporary bracing methods, helical tie-backs offer a permanent structural solution, and installation can usually be completed with minimal disruption inside the home.

After getting bids and talking with a few different contractors regarding what we needed for waterproofing our basement, I was feeling pretty overwhelmed, anxious and stressed out. Elliott was a breath of fresh air. He's a very nice, respectful guy. He is very knowledgeable and was easy to talk to. After speaking with him, I felt more at ease and less anxious about the whole process. Because of Elliott, we plan to move forward with Anchored Walls for our basement waterproofing.

“Anchored Walls did anchors and a full water-proofing system on my dad’s lake house. They were so great to work with from their sales team (Matt), to their front office (Maddy & Deb), their production manager (Lucas), and the foreman and his crew (Kyle & Sopheak). Their GM, Brad, even checked in to make sure everything…”

Are foundation cracks serious or just cosmetic?

Some small, vertical cracks may be normal settling, but if a crack is widening, leaking water, or forming a stair-step or horizontal pattern, it could signal a structural issue. It’s always best to have cracks professionally evaluated to determine whether repair is needed.

What causes foundation problems in the first place?

Most foundation issues are caused by changes in the soil around your home. Drought, heavy rain, poor drainage, and construction on improperly compacted soil can all lead to movement under your foundation. Over time, this movement creates stress on the structure and leads to cracks, shifting, or settling.
