Featured Testimonial

I would recommend this company again and again whenever I can. I have peace of mind for the first time in years - my basement is dry and my bowed walls are repaired.

Wall Crack Repair

Vertical Foundation Wall Cracks 

American Foundation & Basement Repair
 works with vertical foundation wall cracks, which generally do not affect the structural integrity of the foundation. They can be caused by the shrinkage of concrete due to curing, as well as thermal expansion and contraction of concrete. Vertical cracks can be normally repaired by simple epoxy crack injection techniques.

Diagonal Foundation Wall Cracks
We fix diagonal foundation wall cracks, which are generally considered a structural wall crack that could affect the structural integrity of your foundation. They are normally caused by an external lateral force against the foundation wall. In extreme cases, the foundation wall may slide out from under the house framing. Diagonal cracks in foundation walls will normally come in pairs, one in each corner of the same basement wall. Wall stabilization may be required to stop the inward movement of the foundation wall.  The pictures to the left show wall stabilization with Kevlar top anchors and carbon fiber straps.

Horizontal Foundation Cracks

Horizontal foundation cracks are normally caused by rusting rebar in poured concrete foundations. The rebar will continue to corrode and expand within the concrete foundation walls, causing the foundation walls to crack. These types of cracks continue to travel along the steel rebar and in extreme cases, can travel completely around all of the basement walls. Significant spalling can also occur along the crack line and may continue to get larger over time if not properly fixed.

In order to be successful with this type of crack, you must isolate the steel rebar from the air and water that caused the problem. Selecting the correct injection material for this repair is the key. Small diameter cracks can be injected with epoxy. Larger cracks may require carbon fiber staples to strengthen the repair. Spalled areas with any loose concrete must be removed and patched before injecting the crack line.  The picture below shows a rebar crack that the spalled concrete has been removed, note the rusting rebar inside the crack.

Street Creep Foundation Cracks

Wall cracks that sit on the outside bend of a street or at the end of a "T" intersection are known as street creep cracks. They are caused by the street pushing the driveway against the garage floor.  The floor of the garage slides into the basement foundation wall causing it to crack. In most cases, a simple epoxy injection of the crack is sufficient to treat this crack.  However, in more serious cases, the repair may need to be strengthened using carbon fiber corner straps and wall stabilization may be needed.  Lateral force against the driveway by the street must be removed by either installing a larger expansion joint between the street and the driveway or between the driveway and the garage floor.
