The following photos are from a ramp where the existing concrete has deteriorated in areas. R3 was recommended as a repair material. R3 is a rapid setting patch that can be used vertically, horizontally and overhead. The material can be applied from a feather edge to 2" in a single lift. After placing the mortar the concrete will be coated to match the existing color.
