Background
In late July 2024, Typhoon Gaemi struck Taiwan, bringing heavy rainfall. In one residential building in Kaohsiung, massive floodwaters rushed into the underground garage within minutes.
Residents, noticing the sudden flooding, hurried to close the entrance floodgate together—some even used their own bodies to block the water, desperately trying to prevent further inundation of the basement.
This incident was widely reported by local media. It not only highlighted the insufficiency of Taiwan’s urban flood control measures, but also drew renewed public attention to the urgent issue of flood protection for underground garages.

Problems & Challenges
Under extreme weather conditions, conventional assembly-type flood barriers often fail to withstand sudden surges of water. As a result, residents are forced to rely on improvised, high-risk self-rescue measures—sometimes even using their own bodies as barriers.
This incident serves as a stark reminder:
Flood protection for critical spaces such as underground garages must be upgraded to higher standards in order to truly safeguard residents’ safety and prevent greater property losses.
Whenever typhoons hit, underground garages often become the first disaster zone in urban flooding.
However, most so-called “flood doors” available on the market still rely on pieced-together solutions when facing openings wider than 4 meters:
Pieced middle posts
Pieced diagonal braces
Pieced structural stability
And sometimes, pieced luck
Three Major Risks of Traditional Assembled Flood Gates
- Complex installation & too many parts: prone to mistakes and delays, unsuitable for rapid deployment
- Weak sealing points: a single failed joint can cause the entire barrier to collapse
- Complicated structure, difficult maintenance: too many panels, making storage and appearance problematic
