The Supportworks Geo-Lock™ Wall Anchor System permanently stabilizes your basement walls, offering the best opportunity to straighten the walls without the cost and disruption of foundation replacement.
Heavy-duty, galvanized earth anchors are embedded in stable, undisturbed soil outside your foundation wall. Each anchor is connected by a steel rod to a wall plate that provides clamping pressure against the inside of the foundation wall. This method also offers the potential to straighten the wall back to its original position.
Why Wall Anchor Systems Are Needed
While there are a number of potential causes of cracked and bowing foundation walls, the most common reason is pressure from foundation soils.
When clay soils get wet, they can expand and put tremendous pressure on a wall. When this force exceeds the wall’s ability to resist it, the wall begins to fail in different ways. Cracking, bowing and tilting are the most common symptoms of foundation wall failure.
Other factors in foundation wall damage include heavy rains (causing hydrostatic pressure) and exterior slabs such as driveways or porches, that put pressure on the wall by expanding in hot weather (street creep). Large tree roots, soil expansion due to frost, and issues related to poor grading can also cause foundation damage.
One of the problems with foundation soils is that while the earth is continually pressing against the outside of the walls, nothing on the inside is equalizing that pressure. Foundation wall anchors address this problem by “gripping” the inside surface of the wall and countering that pressure.
How Wall Anchor Systems Work
Foundation wall anchors extend out to the stable, hard-packed soil beyond your home, anchoring themselves there and bracing the foundation wall. This stops inward movement entirely — and over time, tightening these anchors can even move your foundation walls back to their original position.
Foundation wall anchors have been used successfully to stabilize and straighten foundation walls since the late 1970s. This repair system has an excellent track record in residential and commercial structures. In fact, in 1992, wall anchor systems were identified by a Chief Appraiser for the U.S. Department of Housing and Urban Development as the most effective means of stabilizing bowing foundation walls.

When to Use Foundation Wall Anchors
- Year-round installation

Wall anchors are the most versatile wall repair method because they can be used to stabilize walls with a variety of problems, including bowing walls, tipping walls, and walls that are pushing in at the bottom.
Wall anchors are installed independently of a home’s floor systems, making them the ideal installation under appropriate conditions.
In order for a wall anchor system to work effectively, several feet of access is needed on the outside of your home. In areas where homes are only a few feet apart, wall anchors are not a valid option.
If this is the case in your situation, we will recommend another wall repair option.
