Cracksof taxiways and apronscausessubsiding due to water ingressintopavement. This affects the usability of the airport. There is a time limitation for repairing as it should be enabled as soon as possible.The objective of this research is to compare the efficiency of concrete repairing by Stitching Dogs by using 3 materials: Steel sheet 1 inch, thickness 3millimeters, steel round bar diameter 6 millimeters and carbon fiber Reinforced Polymer(CFRP)stripby welding using epoxy.It was also comparedwithrepair byepoxy only and with the original concrete that has not been repaired.The repair efficiency was determined by theflexuralstrength, water permeability and abrasion resistance. The test resultsshowed that Stitching Dogswith Steel sheet 1 inch, thickness 3 millimeterswill be the most effective,steel round bar diameter 6 millimetersand carbon fiber Reinforced Polymer (CFRP)respectively. The correlation between the abrasion resistance and the flexural strength was attained as the higher flexural strength was the higher abrasion resistance. However, it was not affectingthe permeability because the size of the woundrepairerwas more affected on the permeability.
