Location • Water tank waterproofing: complete removal of defective old waterproofing, followed by surface repair and re-application of a new system.
• Elevator pits waterproofing: injection works to stop water leakage using polyurethane and acrylic resins.
• Application of cementitious waterproofing systems for long-term protection.
• Structural rehabilitation with cementitious grout and bonding mortars.
The building had already been handed over, but serious leakage issues appeared in both water tanks and elevator pits. Existing waterproofing had failed and required full removal and replacement.
The old system was stripped, concrete was re-profiled and repaired, and a multi-system waterproofing solution (cementitious + crystalline + resin injections) was applied. This ensured complete water tightness and long-term durability.
