The Supportworks Geo-Lock™ Channel Anchor System permanently stabilizes and repairs bowing or tilting foundation walls -- without the cost and disruption of total foundation replacement.
Our system includes galvanized steel earth anchors, which embed in stable soil outside your foundation walls. When the installation is complete, all inward movement is halted, and there is an opportunity for a long-term straightening of your foundation walls.
If your foundation walls are buckling severely, this is just what you need! Call us for a free basement wall repair quote today!

GeoLock® Channel Anchors are a versatile, effective system that can stabilize walls that are bowing, tipping, pushing in at the bottom, tilting in at the top, or showing similar signs of failure. They are installed with minimal disturbance to your lawn and landscaping, often in a day's time or less.
To install your channel anchor system, our foundation repair experts will follow these seven steps:
Before your foundation channel anchors are scheduled to be installed, one of our in-house foundation experts will inspect your problem and map out where each anchor will be placed. When the contractors arrive, their written proposal will show each anchor location.
At each earth anchor location, a section of sod is carefully removed and placed aside to be returned later. Then a plastic sheet is laid down, and the hole is made with a power auger.
After earth anchor holes have been made, a professional foundation contractor will drill small holes through your foundation wall that correspond to earth anchor locations. Then steel anchor rods will be driven through the holes, extending all the way to the earth anchor holes.
The holes in the foundation are each just 1" in diameter. This is much smaller than the large holes and/or sections of concrete block that must be removed for other wall repair techniques.
The threaded end of each steel rod extends through a hole in the center of its earth anchor. Then a nut is screwed to the rod to keep the two parts permanently attached. The anchor-and-rod assemblies are buried in their holes, and earth is carefully replaced and compacted to lock anchors in place.
Each of our Geo-Lock™ Channel Anchors includes a 25-year manufacturer's warrant, as well as our own in-house quality and performance warranty.
After fastening the earth anchor outside, your contractor will mount the steel channel anchor to the inside surface of your foundation wall, fitting each channel anchor over a steel rod.
Unlike uncoated systems that can corrode and rust over time, each Geo-Lock™ Channel has a rust-resistant zinc coating. This keeps them looking neat and clean in your basement for decades to come.
Each channel anchor extends down vertically to the concrete slab floor,
The contractor will now fix each channel anchor's position on the floor by bolting a strong steel bracket to the floor with a pair of heavy-duty bolts.
Tightening the nut on the steel rod that extends through each channel anchor stabilizes the foundation, preventing further bowing or tilting.
At TC Hafford Basement Systems, we take great care in leaving each job clean, neat, and free of any damage to your existing landscaping.
During our cleanup process, all dirt excavated during Step 1 will be returned to the hole. Workers will thoroughly tamp down the fill in each hole to avoid future soil settlement issues.
Finally, the sod will be carefully replaced at each hole location, then raked and tamped to blend seamlessly with surrounding grass.
One thing that makes the Geo-Lock™ system so powerful is the fact that it not only stops your walls from moving inwards -- it also provides the opportunity to straighten your foundation walls over time.
As your walls are returned to their original position, your home's value and appearance will improve -- making your home much more appealing for both you and for prospective home buyers.
More about Foundation Wall Repair.
Both Geo-Lock™ Channel Anchors and Geo-Lock™ Wall Anchors are designed to repair bowed, buckled and tilting foundation walls. This proven repair technique is faster, less disruptive and much more affordable than foundation wall replacement.
In order for a wall channel anchor system to be considered as a viable foundation wall repair option, you will need access to several feet of space outside of your home's foundation.
In areas where homes are very close to each other and this is not possible, wall anchors may not be possible. In cases such as this, we will advise you on other available options for foundation repair.

Total Foundation Replacement involves excavating the dirt around the home to expose the damaged foundation. Anything around the foundation, including gardens, foliage, patios, etc. must also be removed. That foundation is them removed and replaced.
This is an invasive, expensive, time-consuming process that should only be done as a last resort. If the wall is standing, we can almost always repair it.

Carbon fiber is a very high tensile strength material that's almost impossible to stretch. Because it doesn't stretch, it can be 'glued' to concrete walls to keep them from bending or bowing inwards.
Carbon fiber straps have become a fairly common method for reinforcing basement walls. If installed properly, they can effectively hold the center of the wall in place.
Since carbon fiber straps are not attached to anything but the wall itself, they should NOT be used if your basement walls have started to slide in at the bottom or lean in at the top.
Most I-Beam installations begin by standing a beam up against a basement wall. The beam is then connected to the wood floor joists at the top and the concrete floor at the bottom.
If you have rocky soil or there are property line issues, I-Beam systems are a good option for stabilizing bowing, tilting, or inwards-sliding walls. The PowerBrace's patented design takes this one step farther -- with an adjustable design that will also straighten the walls over time.

Helical anchors have been used to stabilize foundations and retaining walls for years -- and they've proven to be quite effective. They are designed like a screw and can be mechanically advanced through the soil with heavy equipment.
To install a helical anchor in the wall one of two things must be done: Either the wall must have a large hole cut in it for each anchor, or the outside of the home will need to be excavated at each anchor point to attach the helical pier section to the rod that will advance the anchor into the earth.
Cutting a hole in the wall will often lead to water issues in the future, while excavating around the foundation is labor-intensive and damaging to landscaping.
Wall anchors have been used successfully since the late 1970's to stabilize foundation and retaining walls. These systems consist of heavy-duty galvanized steel earth anchors that are embedded into the soil away from the foundation wall. They are connected to steel plates with galvanized anchoring rods.
Once installed, wall anchors will hold walls in their current position without any further adjustment. Wall anchors can be tightened during dry periods, allowing for improvement and straightening of the wall over time.
