How to Install the Channel Anchor System
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:
1) Bore Holes for Earth Anchors
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.
2) Prepare the Foundation Wall
After earth anchor holes have been made, one of our in-house, certified foundation contractors 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.
3) Join Rods to Earth Anchors
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 warranty, as well as our own in-house quality and performance warranty.
4) Mount the Channel Anchor
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.
5) Secure the Channel Anchors to the Floor
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.
6) Restore the Landscaping
At Thrasher, 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.
7) Tighten Wall Anchors
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.

When to Use Foundation Wall Anchors
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.
