WARM-HUMID AIRPORT ROOF REFERENCE
Guilin Liangjiang Airport Roof: Drainage and Wet-Weather Sequencing
A membrane and construction review for terminal roof zones where frequent rainfall, humid air, surface condensation and incomplete drainage can affect laps, insulation and covering decisions.
WET-WEATHER PLAN
Keep bulk water out and give construction moisture a defined exit
Positive drainage
Support the membrane and orient laps so incidental water reaches an intended gutter, eave or outlet rather than an insulation joint or closed edge.
Weather-window control
Define when rolls may be opened, how much area may remain incomplete and how temporary edges will be secured and drained before rainfall.
Substrate dryness
Inspect visible water, dampness, condensation, dirt and compatibility before taping or bonding. A break in rain does not guarantee a dry surface.

FAQ
Warm-humid airport roof questions
Can wet insulation dry through a waterproof breathable membrane?
Do not assume it can. Drying capacity depends on the amount of water, temperature, airflow and resistance of every layer. Bulk water can take too long to leave and can damage other components. Wet material should be assessed and replaced or dried under an approved project procedure before concealment.
Why can a bonding surface be wet when rain has stopped?
High humidity and surface temperature can produce condensation or slow evaporation, especially on metal and shaded areas. Check the actual substrate, not only the weather report. Follow approved dry-surface, temperature and preparation instructions before applying tapes or sealants.
