Collin County Community College - 2200 W. University Dr. McKinney Approximately 3,000 s.f. of concrete was mudjacked to raise the concrete as much as 5 inches to pitch the water towards the existing drains. The caulking was removed and replaced. The 6,000 s.f. courtyard had up to 5 different types of concrete from new, to aged and oxidized, as well as 5 different finishes. Our challenge was to clean and prepare the surfaces, apply a coating system that would be semi-consistent and blended to a uniform or similar color. We installed a new HydraStone Dye and sealer to enhance the old and oxidized concrete in the courtyard area. Area to be restored is approximately 6,000 SF plus approximately 120 LF of 3-face concrete landscape curbing.
