Foundation Recovery Systems, founded in 1992, is a subsidiary of Groundworks, a family of companies that offers superior, proven solutions for your foundation repair, structural repair, crawl space encapsulation, dehumidification, and concrete leveling needs. They currently maintain offices in Kansas City, Moberly, Springfield, and St Louis. Foundation Recovery Systems is a recognized accredited member of the Better Business Bureau and devotes its years of experience, industry knowledge and specialized training to help customers protect their homes or commercial buildings from water damage, concrete sinking, and foundation failure.

"As far as we can tell, the work was effective at stabilizing our foundation, and the on-site crew led by Luke was great, informing us of their progress along the way. However, we expressed in advance our concern about protecting some of our landscaping. We were assured the crew would have boards to cover landscaping on which removed dirt would be piled. This turned out not to be the case. I’ve had quite a bit of expense and labor to restore landscaping that was damaged during the work. This damage could have been avoided. Foundation Recovery sends out $500 coupons to advertise for their work. My attempts to contact Joe and FRS to honor even a part of the $500 coupon to help defray my landscaping costs have gone unanswered. Our salesperson, Joe, was not present during the work and has not been responsive to our followup inquiries. We are very disappointed in the poor customer service from Foundation and its representatives. I cannot recommend this company based on their failure to address our up-front concerns, lack of response to our followup requests, and the false advertising that is associated with the coupons."

"I had an egress window installed. It was much more involved than I was expecting.

However, Stratum did its best to remedy the situation and it worked out so that we were all satisfied. The window is good and I would hire them again for another project. However, I would be more careful to have things drawn out, clarified and would ask a lot more questions."

Foundation Repair questions, answered by experts

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.

Foundation settling is normal and expected if just a small amount of settlement occurs within a year or so after construction. This usually results in hairline cracks in the foundation, which aren’t typically a problem. If settlement occurs years after construction, unevenly under your home, or results in signs of structural damage, then it could be very serious. Foundation stabilization and drainage system installation to fix unnatural settlement can cost tens of thousands of dollars and compromise the structural integrity of your entire home.

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

You can patch minor cracks and damage yourself using concrete fillers or mortar. Larger damage may require full replacement of affected slabs. However, water damage to your concrete will never disappear unless you address the root cause causing the water to cumulate. To prevent future damage, you can also waterproof your concrete.

Sometimes cracked brick can mean a foundation problem, such as when the crack appears indoors and is vertical, or long horizontal cracks either inside or outside. If the crack widens at the top, then it’s safe to assume there is structural damage. Other things to look for are uneven floors, diagonal cracks indoors, and doors and windows that stick.
