The following photos are from a school where there were some areas of poor consolidation of the concrete and some voids were present. The loose unsound material was chipped away. The areas are smaller and will not require a form and pour application. A hand applied vertical repair material was needed for the repairs. The areas are abraded to a good rough surface profile and prior to placing the patching material, water will be applied to the substrate. The repair material recommended here was V/O Patch CI. This can be applied from a feather edge to a 2 inches in a single lift.
