"On July 1st (2021), Mel and Stephan from Innovative Basement Authority dug a 30'x18" trench by hand to bury our sump pump discharge pipe. They installed a freeze valve, 30' of 5" PVC, and a discharge grate, exactly where we asked to place it. They had to dig right next to the garage foundation, so this was no easy feat. They also made short work of removing a 4'x4' concrete pad for us. The guys were very courteous, punctual, and seriously hard-working. They did an exceptional job, and in just half a day, I was able to check 1 more item off my honey-do list! We are hoping to hire Innovative Basement Authority for some garage floor concrete work in the near future. Thanks IBA! Brian & Terri MacDonald"

"The job needs to be fixed already it wasnâ t done to completion on day one. I needed the concrete patio to shed water away from the house. It currently is shedding water towards the house. Why I hired them is to correct that problem. My hope is this small issue will be able to be resolved today."

Foundation Repair FAQs, answered by experts

Not all cracks in the basement floor signal foundation problems. As the house settles, you’ll notice very thin hairline cracks, which you don’t need to worry about. Cracks that are 1/8 inch or wider should require sealing, while ones that are 1/2 inch or wider require leveling. However, if you have cracks in your basement floor with heaving, you should call a pro to assess the situation. Heaving can lead to uneven flooring, structural issues, and foundation problems.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

If you don’t have any access to or knowledge of any area underneath your home, chances are it’s built slab-on-grade. You can also look for the concrete around the bottom edge of your structure; if it’s just a few inches tall, it’s likely a slab. If it’s more than that, has any windows, or you have steps leading to your main entrance, you likely have a different foundation style.

Yes, you can fix a block foundation. It’s important to address the issue immediately and have a foundation repair professional understand the severity of the issue and determine the best course of action. If the wall collapses before the foundation is repaired, then you’ll have to reassess your entire foundation.

If your foundation isn’t properly square, there’s a chance that anything you built before detecting the issue may need to be torn down. A major miscalculation could leave some walls of your home unsupported.
