ARDEX's CP Concrete Patch fills spalls, gouges, dormant cracks, birdbaths, and other low areas in existing concrete surfaces, including sidewalks, patios, plazas, courtyards, walkways, driveways, parking garages, pool decks and vertical concrete surfaces. ARDEX's CP can also be used to reform concrete steps and curbs, to create ramps over existing concrete, or to resurface vertical concrete substrates.
