Wall anchors can repair many bowing wall problems, including those that cause cracks, inward bulging and sliding.

Signs of bowing foundation walls

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.

  • Horizontal or stair-step cracking along the foundation walls
  • Diagonal cracking at corners of poured concrete foundation walls
  • Inward bowing or bulging along the walls
  • Walls sliding inwards on the bottom
  • Walls leaning in at the top
  • Wet, clay soils around the home coupled with damaged walls
  • Expansive clay soils present around the structure

Below are images of several foundations that are showing damage from hydrostatic pressure and expansive soils outside the structure.

How we can fix it:

Install Florida Foundation Authority’s Wall Anchors along the bowing walls, and use the system’s clamping pressure to stabilize and restore the wall.

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 stabilize the wall for a permanent solution.

What causes cracked & bowing foundation walls?

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:

  • The type of soil around the foundation
  • The amount of moisture in the soil
  • How far underground the foundation is
  • The temperature conditions

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.

Installing foundation wall anchors

At Florida Foundation Authority, we recommend the Wall Anchor System to stabilize failing foundation walls. Our contractors follow these six steps when installing our warrantied wall anchor system:

Warrantied Wall Anchor System Installation Steps

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 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 Wall Anchor Covers, which will help you conveniently conceal your wall anchor access points.

At Florida Foundation Authority, 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.

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.
