"workers were friendly, but for the price paid to waterproof our basement I expected more of a quality job. I would only give them 2.5 stars but .5's aren't an option. If you decide to go with them, be sure not to be sold things that aren't necessary."

"We had Simstone replace an existing 3 car garage floor. The first day, they removed the floor and prepped it for a new pour. At the same time they removed an 8 ft.apron area of the driveway as well as an existing side walk leading to my front steps. They also set up forms for an overlay of the front step. The next day they poured the garage floor and front step. They came back on the 3rd day and did the apron and side walk. They were fast and efficient. The job they did looks great. They were all very personable and courteous. They cleaned up the entire area where they worked. Would definitely recommend them."

Foundation Repair questions, answered by experts

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.

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.

You can use epoxy-based concrete fillers to repair small cracks and dents in the floor. For larger damages, remove any debris, then patch the cracks or holes with concrete repair products or resurface the entire floor. We recommend using fast-curing products that cure in four hours. You can also buy a pre-mixed concrete patch and leveler if you are only repairing parts of your floor.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

Addressing gaps and cracks reduces heat loss and improves energy use.
