"It was a complex project. They were very careful with their procedures and raised sunken concrete sections next to the house and around a pool to allow for drainage. They filled the major cracks. They were courteous and on-time over several days. After many years the water in the basement problem has been resolved."

Foundation Repair questions, answered by experts

Yes, you can replace a cinder block foundation. If a block foundation is too severely damaged to repair cracks and other issues, replacing the entire foundation is a viable option. The job will require a professional and can take between one to seven days on average to complete, depending on how complex the problem is.

Yes. A foundation wall can usually be replaced, but you’ll want to call a foundation professional.

Yes, it is normal for a block foundation to crack. Some block foundation cracks are more serious than others and indicative of a larger structural problem. On the other hand, minor cracks may not be of immediate concern but should be monitored. Regardless, foundational cracks are not an uncommon response to wear on a structure from time and weather.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.
