How Carbon Fiber Wall Straps Work
Carbon fiber wall straps use epoxy bonding and mechanical anchoring to create a continuous structural link between your foundation wall and the top framing of your home. Once bonded, the wall can’t bow or move inward — the carbon fiber takes the load. Unlike steel I-beams or wall anchors, carbon fiber straps don’t intrude into your basement space, making them ideal for finished basements or limited-space repairs.
When to Use Carbon Fiber for Foundation Crack Repair
Carbon fiber wall straps are best suited for:
Minor to moderate wall bowing (less than 2 inches)
Cracked or displaced foundation walls
Basements showing horizontal or stair-step cracks
Walls under inward hydrostatic pressure
If the wall movement is more severe, we may recommend steel I-beams, wall anchors, or helical tiebacks for additional reinforcement.
Other Structural Reinforcement Options
Steel I-Beams
Provide vertical support for more advanced bowing.
Wall Anchors
Stabilize walls by anchoring to solid soil outside the foundation.
Helical Tiebacks
Installed diagonally into the ground to resist severe lateral pressure.
Exterior Excavation and Basement Waterproofing
When hydrostatic pressure contributes to movement, drainage improvements may also be part of the fix.

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.
