Kaufman Products, Inc. was consulted, and a repair process was submitted to the Maryland State Highway Administration, District 7 Area Engineer. The process, Rout & Seal, involves removing a small section of concrete, centering the crack, and cutting a 1.5”- 2” slot into the remaining base concrete. Then gravity feeding the slot full with SurePoxy LMLV Epoxy Resin, thus “welding” the base back together with a flexible epoxy to allow for the minor future movement of the concrete. After addressing the crack, a 2” concrete topping was repaired using SurePoxy HM as the Bonding Agent and applied to the remaining area that had been chipped out. While the epoxy was wet, the “special colored concrete mix” was used to fill the area and stamped to match the existing pattern
The recommended process was accepted, and repairs were performed. Two years after completion of this repair, upon inspection, the original cracks have not reappeared!
