"I wish I could give Innovative Basement Authority a negative rating. Run away from this company as fast as you can. Beware- they are changing their name to Ground Works. Probably because of all the negative reviews. We paid a substantial amount of money to install one of their basement systems after having water problems. The initial sales guy was a very high-pressure seller, trying to get us to sign a contract the same day he came out. Fast forward a year. They told us they needed to come out for an inspection. The sales guy ?found? $40,000 work of additional work that was ?urgent?. He used scare-tactics and tried to convince us we needed to sign on the dotted line immediately. Because of course mold is going to make my family sick. It seemed sketchy to me, but I was able to get the guy to leave without us signing that day. I immediately called our trusted home inspector, and he said the sales guy was trying to sell us things we did not need. He also said he had talked to others"

Foundation Repair questions, answered by experts

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

You have different options depending on the scale of repair needed. If you are repairing minor cracks that are between ¼ inch to 1.5 inch wide and less than half an inch deep, a self-leveling polyurethane sealant would be your best choice. Polyurethane sealants dry to the touch within one to two hours. Since they come in a tube applier, you also have the option to complete the repair without emptying out your garage.

Cement companies offer a wide variety of services, including delivering and pouring concrete for home foundations, walkways, patios, driveways, concrete steps, pools, pool decks, and more, plus concrete repair and patching. Most companies also have the ability to demolish and haul away old concrete landscaping features. It’s a good idea to reach out to a few different companies before hiring to make sure you choose one that can tackle the entirety of the project you have from start to finish. This method will typically save you some money over hiring multiple contractors.

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.

Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.
