Carbon Fiber Foundation Wall Repair Solution

Carbon fiber is a lightweight, fabric-like material that is stronger than steel when applied correctly. It is used to keep airplanes together and reinforce bomb shelters.

Carbon Armor wall straps installed on basement block wallsCarbon fiber wall straps are used as an unobtrusive solution on basement walls bowing, cracking or buckling from lateral pressure caused by high-moisture soil expanding. The deflection to the foundation wall should be no more than 2 inches and cracks shouldn’t be too wide. The straps are able to reinforce the foundation wall and prevent any further bowing, permanently reinforcing against outside pressures.

The installation process doesn't take long. First, the surface of the wall where the carbon fiber straps will be applied is ground flat, and a structural epoxy adhesive applied, creating a gluey surface. After the epoxy sets, the carbon fiber straps are applied and anchored at the top to the sill plate of your home and at the bottom to your foundation floor. These anchors can have mechanisms that further tighten the carbon fiber straps, helping to straighten the wall. 

There is no outside excavation and no heavy equipment required. With an extremely low profile, it’s easier to work around when finishing your basement or doing interior work.

Frequently Asked Questions

  • Carbon fiber wall straps are an advanced foundation repair system. They usually look like a dark fabric made of woven carbon filaments. The material is very lightweight, flexible and much stronger than steel when applied properly with a binding polymer like a structural epoxy. Using epoxy as a base, carbon fiber straps are attached to your foundation. They have high stiffness and won't bend under pressure or extreme temperatures. 

  • Carbon fiber straps are used to fix foundation problems like bowing, buckling and cracking basement walls. 'Stair step' patterned and horizontal cracks along your foundation wall, or an inverse lean, are indicators that you need structural support. More widespread, long-term problems, like severe cracks or extreme bowing over 2 inches, may require a different approach.

  • Before installing carbon fiber straps to repair a foundation, you must first grind the surface of the wall where the straps will go, creating a smooth, debris-free surface. After this, a base glue-like structural epoxy adhesive is applied and given time to set. Once set, the carbon fiber straps are applied, bonding to the epoxy, and another layer of epoxy is applied on top. Carbon fiber straps can be applied by themselves in certain situations or anchored at the top and bottom to help straighten foundation walls.

  • After carbon fiber foundation wall repairs are complete, they require very little, to no maintenance. If applied effectively, they work with no signs of wear or tear.

  • A strong benefit to carbon fiber repairs is they are essentially a permanent solution and extremely unobtrusive to any work you might do when finishing your basement. You're freer to make any kind of adjustments or work on your basement while the straps are in-use. You could even paint directly over them or cover them up with walls.

  • Foundation repairs using carbon fiber usually take around a day. The process itself isn't complex; but preparing the wall by grounding it down for a smooth, debris-free surface takes some time and letting the structural epoxy resin set properly takes a little while to set, before the straps can be installed.
