When property owners are looking for comprehensive solutions across the Upper Midwest, a common frustration surfaces. I remember a call from a property manager outside Sioux Falls who had contracted a leveling crew to address a settled commercial sidewalk section the previous spring. By the following October, the same exact section had dropped again. It was not as far down, but certainly enough that the serious liability concern was back.
When we arrived and assessed the situation, a significant void had formed directly along the edge of a utility trench that had been poorly backfilled with loose soil at the time of installation. The previous leveling crew had successfully lifted the slab but had completely failed to inject the void beneath it. We meticulously pressure-filled the entire void with high-density polyurethane foam, permanently stabilized the soil along the trench line, and then lifted the slab flawlessly back to grade. That section has stayed perfectly in position through two full, brutal freeze-thaw cycles since.
Concrete lifting that holds requires deeply understanding what the slab is actually sitting on, not just focusing on where it ended up after it moved.
Technical Construction Solutions was founded by Freddy Lewis, who grew up heavily in a highway construction family and spent 15 rigorous years in the field before building TCS specifically around advanced foam technology and its highly technical applications in lifting, undersealing, and void filling.
That specific background, highway lifting, commercial infrastructure, deep soil stabilization, entirely shapes how this crew approaches every single concrete project. We operate on a strict principle: diagnosis first, void assessment second, lift third. If your concrete is sinking, has suspiciously settled after a previous repair, or is showing clear signs of soil instability beneath it, a free estimate is the absolute right starting point.
