Repair of deteriorated reinforced concrete (RC) elements may be necessary to restore their strength and serviceability. In this research, unsaturated polyester resin (UPR)-mortar is used to repair one-way RC slabs. The performance of the patched RC slabs is investigated experimentally by comparing their behaviour under concentrated load with the corresponding normal slab. The obtained load–deflection relationship up to failure and the cracking failure mode are assessed to determine the efficacy of the UPR-mortar in restoring the strength and serviceability of the slabs. In addition, theoretical ultimate loads determined on the basis of the yield line theory are used to assess the effectiveness of UPR-mortar to restore the strength of the damaged RC slab. As long as a proper execution of repair is carried out, the results indicate a satisfactory performance of UPR-mortar to be used for repairing the damaged RC slabs.
