Concrete flatwork repair is the process of repairing concrete flatwork. Flatwork is concrete that is placed in a horizontal plane, such as a floor, driveway, or sidewalk. One of the most common problems with concrete flatwork is cracks. Cracks can be caused by a number of factors, including temperature changes, freezing and thawing cycles, settlement of the substrate beneath the concrete, and overloading. Cracks in concrete can be repaired by using a variety of methods, including epoxy injection, polyurethane injection, crack filling compounds, and carbon fiber reinforcement.

Concrete flatwork is concrete that is placed in a horizontal or nearly horizontal plane. It is often used for floors, foundations, pavements, and roadways. Concrete flatwork may develop cracks due to drying shrinkage, thermal expansion and contraction, overloading, or poor construction practices. If the cracks are relatively small and the concrete has not lost its structural integrity, the cracks can be repaired by injecting them with a polyurethane foam. If the cracks are too large or if the concrete has lost its structural integrity, then the entire slab needs to be replaced.
