Assessment of the long-term durability of concrete repairs on existing structures can provide useful data to support selection of strategies for ongoing remediation and service life extension. Condition surveys of large reinforced concrete storage sheds enabled study of repair methods for different forms of damage and deterioration. Reinforced concrete piles supporting the sheds exhibited multiple deterioration mechanisms and had undergone various repair techniques over 30 years. Deterioration included a combination of reinforcement corrosion alkali-silica reaction and salt hydration distress (or physical salt attack). Of these reinforcement corrosion was the greatest concern due to the impact on load bearing capacity of the piles. Floor slabs of the storage sheds had experienced different types of cracking and been exposed to sugar attack and heavy vehicle traffic. This paper presents details of the environmental conditions concrete materials and construction issues contributing to the observed deterioration. In addition the performance of previous repair methods including crack repair shotcrete patch repair protective coatings and cementitious waterproofing slurries is analysed. The current remediation program is also discussed.
