"The worker who came over saw my situation and unoffically suggested a repair that would be cheap for me rather than have him and his crew come out and charge me a few thousand. I appreciated that he wanted what was best for me and not necessarily best for his company."

"I would like to thank Mariano and crew from Chicago Basement Systems for the very efficient work they performed in my home crawl space. They replaced my failed sump pump and drain tile; installed a Sani-Dry Sedona dehumidifier; installed a backup battery; installed steel beams and piers; installed a waterproofing membrane on the crawl space floor; and encapsulated the entire crawl space. Now I don't smell odors seeping from my crawl space, and my house no longer shakes when cars drive over the city speed bump outside my house. Also, I can now use my clean dry crawl space for extra storage. Thank you Chicago Basement Systems for peace of mind knowing that this project has a lifetime transferrable warranty. I highly recommend Chicago Basement Systems for crawl space repairs!"

Foundation Repair questions, answered by experts

Yes, it’s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it’s important to find a solution.

Foundation settlement should be a concern if you notice it happening suddenly and years after construction, if the settlement results in signs of structural damage in your home, or if it happens after a flood, nearby sinkhole, or earthquake. Some signs of severe foundation settlement that should prompt you to call a repair specialist include sloping or uneven floors, large cracks in your foundation, moisture issues or pest infestation in your basement or crawl space, and an uneven roofline.

It’s usually not a big deal if your foundation sinks between 2 and 3 inches into the ground after construction, provided the settlement occurs evenly. This is usually indicative of normal settlement that occurs as the soil under your home adapts to the weight of the structure. If the home sinks more into the ground or the settlement occurs unevenly, leaving portions of your home to sink further down than others, then call a foundation repair specialist to address the issue and avoid additional damage.

You'll find a slurry of natural and synthetic polymers, rubbers, epoxies, and resins used to bond old concrete to new concrete. The right bonding agent depends on the method of concrete pouring you choose and whether you're adhering concrete over concrete or concrete over sand and gravel. Some concrete resurfacing mixtures contain bonding chemicals as well.

Concrete can crack from general wear, improper installation, or in response to uneven support from the soil underneath. Small, thin cracks on the surface of aging concrete are usually a result of normal wear and tear, while cracks on new concrete more likely indicate a problem with installation. Larger cracks or uneven steps can signify a much more severe issue. A concrete contractor should be able to diagnose the cause and repair concrete cracks for you.
