See how we repair foundation cracks with carbon fiber

Carbon fiber wall straps are one of the strongest and most reliable ways to stabilize cracked or bowing foundation walls. Made from carbon fibers that are stronger than steel, carbon fiber straps permanently bond to your foundation walls without bulky hardware or invasive construction. They’re a cost-effective, low-maintenance solution that stops further movement and preserves your home’s structural integrity.

Our proven foundation crack repair method for leaning or bowed walls

1. Carbon Fiber Straps

For minor to moderate bowing (less than 2 inches), carbon fiber straps can reinforce the wall and prevent further movement. These high-strength materials are bonded to the wall with epoxy, creating a durable and non-intrusive solution.

2. Steel I-Beams

For moderate to severe bowing, steel I-beams (also known as wall braces) are installed vertically along the inside of the foundation wall. These beams provide strong support and prevent further inward movement.

3. Wall Anchors

Wall anchor systems involve securing a plate to the interior wall and connecting it to an anchor buried in stable soil outside. By gradually tightening the system, the wall can be straightened over time.

4. Helical Tiebacks

In cases where the external soil pressure is significant, helical tiebacks can be drilled into the ground to provide additional lateral support and stabilize the wall.

5. Exterior Excavation and Waterproofing

For extreme cases, exterior excavation may be necessary to relieve soil pressure and straighten the wall. Waterproofing solutions can also be applied to prevent future issues. Fixing the issue starts on the outside. First, ensure water flows away from the home, that gutters are functioning, and that downspouts correctly discharge away from the home.

How to Identify and Repair Bowing Walls in Your Home

Bowing walls are a common structural issue in homes, particularly in areas with expansive clay soil like St. Louis. If left unaddressed, bowing walls can compromise the stability of your home and lead to costly repairs. Understanding the causes, warning signs, and repair solutions can help homeowners take action before the problem worsens.

Signs of Bowing Walls

Early detection is crucial for preventing severe structural damage. Look out for these warning signs:

  • Visible inward curvature of basement walls

  • Horizontal or stair-step cracks in masonry

  • Water infiltration or damp basement conditions

  • Doors and windows becoming misaligned

What Causes Bowing Walls?

Several factors can contribute to bowing basement or foundation walls, including:

  • Hydrostatic Pressure – Excess moisture in the soil can create significant lateral pressure against your foundation walls, causing them to bulge inward.

  • Expansive Clay Soil – St. Louis is known for its clay-rich soil, which expands when wet and contracts when dry, leading to foundation movement.

  • Poor Drainage – Improper water management around your home can exacerbate soil pressure and cause walls to bow.

  • Tree Roots – Large tree roots growing too close to your foundation can exert pressure and contribute to wall movement.
