Concrete Crack & Floor Repair in Lafayette, IN

Concrete crack and floor repair is part of almost every floor we coat in Lafayette. A coating copies whatever is under it. A pitted, cracked or salt-scaled slab will show through a new finish and can break the coating along the damage. We repair the concrete first, then coat. We also do repair work on its own when you want a sound floor without a full coating system.

Why so many floors here need repair

Lafayette's median home was built in 1971, and about 17.6% of homes date from before 1940, according to 2019 to 2023 American Community Survey figures summarized by Point2Homes. Decades of settling, freeze-thaw cycles and road salt leave their mark. The Lafayette 8 S weather station records an average January low of 17.7°F, and the area's record low is -25°F. Every thaw sends meltwater into cracks, and every freeze widens them a little. Salt adds its own damage. The 2008 South Dakota DOT literature review by the Michigan Tech Transportation Institute found that sodium chloride makes freeze-thaw scaling worse and that magnesium and calcium chlorides attack the cement paste.

Common problems we fix

• Hairline and shrinkage cracks: filled and ground flush so they do not telegraph through the coating
• Wider settlement cracks: cut open, cleaned and filled with a rigid or semi-rigid repair material
• Spalls and pop-outs: broken surface pieces removed and patched to level
• Salt scaling: flaked surface ground down and resurfaced where it is deep
• Chipped control joints: joint edges rebuilt and joints filled or left open as planned
• Low spots: areas that hold water filled or feathered to improve drainage

Cracks that move

Some cracks are stable. They formed as the concrete cured or settled years ago and have not changed since. Those fill and stay filled. Others keep moving because of soil movement, heaving or structural issues. Filling a moving crack only hides it for a while. If we see signs that a crack is active, such as fresh breaks at the edges, one side sitting higher than the other, or a crack that has clearly widened, we tell you that the slab needs structural attention first. HomeAdvisor lists structural foundation repair at $2,150 to $7,730 or more, and that work is outside what we do.

Resurfacing heavily worn floors

When salt scaling or wear has damaged a large share of the surface, spot repairs are not enough. HomeGuide lists concrete resurfacing at $3 to $7 per square foot. A resurfacer restores a flat, sound top layer that can be left bare or coated. We tell you at the estimate whether patching or resurfacing makes more sense for your floor.

How repair fits into a coating job

On a coating job, repair happens right after grinding. Grinding exposes the real extent of the damage, so we sometimes find more than was visible at the estimate. If that happens, we show you, explain the extra work and get your written approval before going further. Repairs then cure and are ground flush before the base coat goes on.

Repair without a coating

Some owners just want a sound slab: a garage before a sale, a basement before new flooring, or a shop floor with dangerous broken joints. We do those repairs as a standalone job and quote them separately.
