"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

Ensures structural stability and long-term safety of the building.

Yes, a house can collapse from severe foundation problems if they are left unchecked. However, this is a rare occurrence that typically takes many years to develop, and a partial collapse is more likely than a full one. Homes on hillsides or in areas with frequent washouts are at a higher risk. Barring a natural disaster or other extreme circumstances, clear signs of major issues will be apparent long before a collapse is imminent. It is crucial to conduct routine foundation inspections and address any problem, no matter how minor it seems, as soon as possible to avoid threatening the structural integrity of your home.

No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

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.
