Make OR Break Factor
Given that the brine saturator was to be fixed in its original position post-repair, all sectional sizes, had to be kept the same, giving us a tolerance of only 50mm on all sides.
THE CHALLENGE :
- The structure was suffering from chloride-induced corrosion of steel, de-lamination of concrete and reduction in reinforcement size.
THE ODDS :
- In a few beams, more than 75% of the steel reinforcements was corroded
- All immediate supports would have to be removed after repair
OUR RESPONSE :
- Firstly, curative and preventive measures were taken for corrosion, after which patching up was done for all damaged concrete sections, while structural elements were externally reinforced
- Protective coatings were applied on all RCC members
- Even after completion of the project, the performance of the structure was regularly monitored for a period of time to gauge efficacy of the interventions
