These photographs represent concrete that was once plain, cracked, and/or out of level. But because the state of the art overlay system we use has unmatched bonding capabilities, we are able to apply 3/8” of this special mix over any kind of stained, cracked, or uneven concrete base! Not only are there unlimited colors and designs for the overlay, it also won't shift with "freeze - thaw" and create a tripping hazard like real slate, brick, or stone.
