About A-1 Concrete Leveling Muncie A-1 Concrete Leveling and Foundation Repair Muncie provides the highest quality concrete leveling and foundation repair service available in the Muncie, Indiana area and surrounding region. A-1 Patented Technology Superior Advantage A-1 Muncie, IN leverages modern concrete leveling techniques to provide exceptional results with minimum downtime. We can have you back using your driveway, sidewalk, or any repaired surface the same day. A-1 uses the smallest diameter hole in the industry (one inch) which leaves your concrete looking almost new, and provides the highest structural integrity. Because of the low pressure used, we carefully manage the leveling process, reducing stress on the slab lower and providing a more uniform lift. Holes are filled with non-shrinking grout and preserve a beautiful finish. 100% Natural Pumping Compound Our hydraulic lifting material is a specially processed grade of Agricultural Limestone (AgLime) - a 100% natural product of the earth. This is the same material used by farmers on their fields. As a result, there are no residual chemicals to deal with and no concerns about leaching of pollutants into the surrounding soil or aquifer.
