"This is a very professional and high quality company. They completed the countertops in two days. The epoxy had a flaw from the manufacturer and they come back immediately and re surfaced it. The counters look like glass. The price was reasonable. We are very happy with the result. The only negative is they could have done a better job cleaning up."

Concrete 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.

The actual foundation repair costs will depend on the extent of the damage, how many blocks you need, labor costs, and material costs. As an estimate, the average repair costs for a cinder block foundation fall between $350 and $25,000. Because the range is so large, it’s important to call a professional foundation repair company and have them assess the damage and estimate the repair costs.

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

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.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.
