Description
A package emphasizing the combined airtightness and waterproofing of the roof, suitable for renovations of older buildings. On-site windshield testing is performed to locate leaks, followed by integrated sealing and waterproofing of the leaking areas. First, fill structural gaps, then apply a double-layer airtight and waterproof functional coating, and install special sealing sleeves at pipe penetrations. Airtightness is retested after construction to verify effectiveness.
Delivery includes before-and-after airtightness comparison data. This package’s key feature is “air sealing equals water sealing”; all sealing processes are designed in stages according to the amount of leakage, rather than a uniform application.
