Challenge
Extensive concrete spalling, reinforcement corrosion and leakage affecting multiple floors of an ageing commercial building.
Investigation
Visual inspection, cover meter survey, half-cell potential testing and carbonation depth assessment.
Engineering Solution
Reinforcement treatment, concrete repair using polymer-modified mortars, protective coating application and terrace waterproofing.
Outcome
Restored structural integrity, eliminated active leakage and improved durability for extended service life.
