The original waterproofing system was substandard, resulting in widespread leakage that could not be resolved through minor repairs. To address this issue effectively, Qinglong implemented a high-performance composite waterproofing solution—combining Hot-Laid Non-Curing Waterproof Coating with a 2mm PCM Reactive Adhesive Waterproof Membrane.

This dual-layer system offers enhanced protection by forming a continuous, flexible barrier that seals all weak points. The approach significantly reduced construction time, minimized defects, and ultimately eliminated all signs of water leakage, ensuring long-term structural durability and reliability.
