Our before-and-after rehabilitation projects clearly highlight how deteriorated structures are restored to regain their structural integrity and extend service life. Through advanced methods such as jacketing, CFRP wrapping, protective coatings, linings, and cathodic protection, we address reinforcement corrosion, fire and blast damage, earthquake impact, and construction defects. These solutions not only restore lost capacity but also upgrade durability, ensuring the structure performs reliably under future loads and environmental conditions.
