When diagnosing a faulty concrete structure, the cause of the fault or deterioration should be established so that the most appropriate solution to the problem can be selected. For example if corrosion of the reinforcement is the main cause of deterioration, then one might call for an impermeable or less permeable repair system which may be found among the resinous system. However one should always bear in mind the compatibility of the system with the old or deteriorated concrete structure.No matter what repair system is chosen one of the requirements of a repair system is the ability to provide an adequate bond between the repair and the old concrete. Ideally the bond strength should be such that the composite structure behaves as monolithial.The factors which in the authors’ view plays an influential role in creation of bond between the repair and old concrete, has been examined in this paper and some comparison is made between the different repair systems.
