Wall anchors can repair many bowing wall problems, including those that cause cracks, inward bulging and sliding.
If your foundation walls are bowing, buckling or are showing signs of inward movement, repair work is a necessity. These symptoms are a sign of weakening walls and potentially serious damage.
If you've noticed these problems in your home, Erickson Foundation Solutions can provide you with a permanent solution. We handle all types of foundation repair problems in Amherst, Windham, Bedford and the nearby areas, and we can solve your problem. Call us today to get a free estimate!
Foundation walls move inward primarily due to expansive soils and hydrostatic pressure on the walls from outside. However, foundation walls may also crack due to many other outside causes, including foundation settlement. Our foundation experts will accurately identify the cause of your home's foundation problems.
Below are images of several foundations that are showing damage from hydrostatic pressure and expansive soils outside the structure.

Install Erickson Foundation Solutions's Geo-Lock™ Wall Anchors along the bowing walls, and use the system's clamping pressure to stabilize and restore the wall. When space issues prohibit wall anchor installation, we recommend installing the PowerBrace™ Wall System or CarbonArmor® Wall Reinforcing System.
Soil anchors are placed in the ground outside the home. Steel rods attached to soil anchors extend through the foundation wall and wall plates. Wall plates distribute clamping pressure. Tightening nuts on the threaded ends of the rods stabilizes the wall for a permanent solution.
These two clay samples started out exactly the same in size, weight, and composition. The sample on the right was allowed to dry out, while the one on the left we kept moist.
If a small sample of clay can gain this much volume when it gets wet, just imagine how dramatic the changes are in the soil around your home!
The soils around your home can put enormous pressure on foundation walls. The amount of pressure they exert depends on four factors:
There's constant pressure on your foundation walls from the outside, but the only thing holding up your foundation wall is the wall itself. Hydrostatic pressure, expansive clay soil, and frost can all exert enough pressure to cause walls to lean or even collapse.
Gutters and downspouts can also contribute significantly to foundation wall problems by allowing large volumes of water to collect in the soil around your structure.
If roof runoff is not directed away from your foundation, the soil around the foundation will become heavier and more expansive as it's saturated with water.
At Erickson Foundation Solutions, we recommend the Geo-Lock™ Wall Anchor System to stabilize failing foundation walls. Our contractors follow these six steps when installing our warrantied wall anchor system:
Before the installation, earth anchor locations will be determined to maximize system effectiveness. When the foundation contractors arrive, their proposal will show the location of each earth anchor in the yard outside your house.
At the beginning of each earth anchor installation, sod is carefully removed from your lawn and placed aside for later. A sheet is laid down to help protect your lawn and landscaping, and an earth anchor hole is made using a power auger.
Once the hole has been excavated, we will core a small hole through your basement wall. Then, a steel anchor rod will be driven through the wall and soil, extending through a hole in the center of the earth anchor.
One way our wall anchor system is superior to other methods is that the hole created in the foundation wall is very small - 1" in diameter. Other methods may require a large hole or section of concrete block to be removed during installation.
After securing the end of each anchor rod to its earth anchor, these assemblies are buried in the ground, using soil removed earlier. To resist corrosion damage, each of our earth anchor systems is designed with galvanized steel.
Each of the Geo-Lock™ Earth Anchors we install includes a 25-year warranty against manufacturing defects, as well as our own in-house quality and performance warranty.
Once the earth anchors have been installed, our foundation repair experts will mount a wall plate over each anchor rod end that protrudes from the basement wall. Screwing a large nut to the threaded end of the anchor rod secures each wall plate and stabilizes the wall as the nut is tightened.
If your wall anchors are being installed in a finished basement, be sure to ask us about our Hide-A-Way® Wall Anchor Covers, which will help you conveniently conceal your wall anchor access points.
At Erickson Foundation Solutions, we take pride in leaving each job clean, neat, and free of damage to existing landscaping. As part of our cleanup process, we fill holes completely with dirt saved earlier and tamp filled areas to ensure that depressed areas will not be created as the soils settle over time.
We will also replace all sod, carefully grooming it with a rake to help it to blend in with surrounding grass for a seamless landscaping restoration.
Geo-Lock™ Wall Anchors do more than just stop the inward movement of your foundation walls -- they also provide the opportunity to straighten your walls over time.
Eventually, your walls can be significantly repaired, or even returned completely to their original position. This is a powerful way to restore value to your home and return your home to looking solid, stable, and attractive -- both for you and for prospective home buyers.
Saving a wall with the PowerBrace™ system. This innovative system stabilizes bowing walls and can even straighten walls over time.
In some cases, a wall anchor system can't be used to repair a bowing wall because the yard outside the house isn't accessible. When we at Erickson Foundation Solutions encounter this kind of problem, we suggest that you install our PowerBrace™ Foundation Wall System or CarbonArmor® Wall Reinforcing System.
The PowerBrace™ is a patented foundation wall repair system designed to stabilize failing basement walls and also allow for potential straightening over time. This product is a great option when access to the yard outside of the home is not possible and bowing, buckling wall problems need to be solved.
The PowerBrace™ is an I-beam system that has several advantages over traditional "old school" systems. This includes its rust-resistant zinc coating and a design that makes it possible not only to stabilize bowing walls, but also to straighten these walls over a period of time. Installation of a PowerBrace™ system can be conducted quickly in your home, with no disruption to your lawn, gardens, foliage, or other landscaping.
Strips add strength. When epoxied to the foundation wall, strips of carbon fiber fabric provide reinforcement that's 10 times stronger than steel.
When soil pressure causes a foundation wall to bow inward and crack, one solution is to stabilize and strengthen the wall using CarbonArmor® bracing technology. The CarbonArmor® Wall Reinforcing System relies on the exceptional strength of carbon fiber fabric – 10 times stronger than steel.
Concrete is strong in compression, enabling a foundation wall to withstand extreme downward pressure. But concrete is weak in tension. A foundation wall can't stretch or bend in response to sideways soil pressure, so cracking and bowing problems sometimes develop.
When installed against a foundation wall with special structural epoxy, CarbonArmor® fabric is exceptionally strong in tension. This reinforcement treatment enables a cracked or bowed foundation to withstand soil pressure without sustaining further damage. CarbonArmor® repairs can be made quickly and affordably, and this low-profile repair is easily hidden with a coat of paint.
