There are various methods that professional contractors use to straighten bowed foundation walls including:

1.Installing wall anchors

This is considered one the traditional methods of straightening basement walls. It involves the use of large steel plates that are buried vertically in the ground. The steel plates are placed on the outside surface of the foundation. A long steel rod with threads is then passed through a hole that is drilled through the foundation wall. The rod is tightened from the interior of the basement wall. The resistance of the rod is used to pull the wall back until it is plumb.

Although effective, this approach requires maintenance as the rod must be tightened regularly after installation. The success of this method also depends on the soil stability.

2. Using carbon fiber

Carbon fiber is taking the foundation repair industry by storm. The material is light, durable and strong. Once installed, there is no need for regular maintenance, making it a great choice for homeowners who don’t have the time for regular tightening.

Carbon fiber strips are applied to the wall. The number of strips to be applied as well as their placement is determined based on engineering data collected by basement contractors. The strips are applied to the wall to stabilize the wall and prevent further bowing.

3. Steel channels

These are used when the bowing is extensive. The steel pieces are used to anchor the footings of the foundation.

It is important to talk to an experienced foundation repair contractor to determine which method or combination of methods will work best for your foundation. This ensures long term success.
