Basement Wall Crack Repair

There are 3 types of wall movements that lead to basement wall cracks and failures. Proper wall repair requires a 3-part system for a complete solution.

Bowing Wall

Bowed Wall Solution

A basement wall that is cracked and bowing is repaired using our Carbon-Kevlar strap. Fortress has the strongest strap and system available. The strap keeps the wall from further bowing. The Fortress strap uses our Epoxy Rivet Technology (ERT) which forms a 2-part adhesive bond that acts like 8,000 mechanical rivets ensuring that your wall is stronger than the original.
Shearing Wall

Sheared Wall Solution

A basement wall that is cracked and sheared needs to be repaired using our bottom anchor that attaches to our Carbon-Kevlar strap. Because preventing shear requires strength, we made our bottom anchor over 5 times thicker and 125 times stiffer than the competition. We use a dual leg solution with specific contact lengths engineered to achieve a 200% safety factor. Our bottom plate anchor is the best in the industry.
Tipping Wall

Tipped Wall Solution

A basement wall that is tipped needs to be repaired using our top anchor that attaches to our Carbon-Kevlar strap. The Fortress top anchor is mechanically fastened to the rim joist to engage with the building’s floor system, providing a stronger, more durable anchor. Fortress has the only top anchor that utilizes post-tensioning technology. This prevents any movement of the basement wall.

The InvisiBeam System uses Carbon Fiber that is stronger than steel.

Cracked Walls

A basement foundation has failed when the structural integrity is compromised. When this happens, the wall can develop a horizontal or vertical crack. When walls are constructed from concrete masonry units or CMUs (cement blocks) the cracks can look like steps, or a combination of horizontal and vetical cracks. The failures can be caused from any number of causes, from excessive moisture to drought, or even heavy machinery located to close to the home.

Cracked Walls

Basements are held in place at the top, by the first floor and the bottom by the basement foundation slab. When the center portion of the wall is not strong enough to hold pressure from the external soil, they can bow inward. If you can arrest the bow early enough the structural integrity of the wall can be maintained. This is the key to preventing an occurrence of further wall failure.

fixed wall

The InvisiBeam System with Carbon-Kevlar straps permanantly stop the cracking and bowing to keep the wall structurally sound.

InvisiBeam has been repairing foundations using carbon fiber for almost 20 years.

“A basement wall fails when the pressure of the soil exceeds the lateral strength of the wall.”
