How long does concrete patching last in New Jersey's climate?

Quality patching with polymer-modified repair mortar in a properly prepared surface should last 5 to 10 years or longer. New Jersey's freeze-thaw cycles are the primary challenge and water entering micro-cracks in the patch expands as it freezes and eventually causes delamination if the product has a different expansion coefficient than the surrounding concrete. Scaldino uses products matched to the host concrete's characteristics to maximize patch longevity.
