Foundation Repair questions, answered by experts

You have different options depending on the scale of repair needed. If you are repairing minor cracks that are between ¼ inch to 1.5 inch wide and less than half an inch deep, a self-leveling polyurethane sealant would be your best choice. Polyurethane sealants dry to the touch within one to two hours. Since they come in a tube applier, you also have the option to complete the repair without emptying out your garage.

Barring extreme home foundation problems, most horizontal foundation cracks are fixable using one or more methods. Most of the repair methods require professional expertise to accomplish, and include plate anchors, steel reinforcement, soil anchors, reconstruction, or carbon fiber strip applications. Contacting a professional to diagnose the problem early can minimize repair expenses.

Most single-story homes don't have foundations strong enough to support a second story, but they can be reinforced for an addition. A structural engineer can assess your foundation and what needs to be done to get it ready. They'll look at any cracks or unevenness in your current foundation and consider any special framing or beams your home needs, especially if it’s in a high-wind or hurricane area.

“To support a second story, many structural engineers will require that you install additional concrete piers in the crawlspace,” says Tschudi. “This involves hand excavating, pouring a large concrete footing—usually with specially coated rebar—and then building concrete piers right up to the girders.”

Foundation repairs typically require a building permit, depending on the state and local jurisdiction. Make sure your contractor follows all building codes, and a local building inspector will review all work to ensure that it is up to code. Not following local building codes can prevent the sale of your home and potentially put your home at an even greater risk of damage if the work isn’t done properly. You can call your local municipal office to confirm that your contractor has filed the necessary permits.

Underpinning is a type of foundation repair in which a repair specialist installs piers under your foundation to provide additional support for the concrete and structure above. Foundation repair is an umbrella term that includes many other repair methods, including foundation crack repair, waterproofing, cosmetic repair, concrete block wall stabilization, and more.
