Flood Barrier for Metro/Subway Entrance
Protect metro and subway entrances from flash flooding--deploy fast when warnings arrive.
Underground entrances can flood quickly during heavy rain, putting passengers, equipment, and operations at risk. Our removable barrier solution uses fixed side channels and stackable panels to protect stairwell entrances and access openings--while keeping entrances open during normal operations.
Engineered for Transit Systems
Rapid Deployment
Fast emergency response with stackable panels designed for quick manual installation during flood warnings.
Modular Protection Height
Stack panels as required to meet specific protection levels--flexible configuration for varying flood scenarios.
Replaceable Sealing
Reliable sealing gaskets that can be replaced over time, ensuring long-term performance and maintenance efficiency.
Reusable System
Compact storage on-site enables repeated use across multiple flood events--cost-effective long-term solution.
Material Options
Choose aluminum for lightweight deployment or stainless steel for harsh environments--tailored to your needs.
Unobstructed Access
Panels removed during normal operations keep entrances fully open for daily passenger flow and operations.
Why Metro/Subway Entrances Flood
Intense rainfall overwhelms surface drainage and directs runoff into stairwells
Underground facilities have limited tolerance for water ingress
Flood events require fast, repeatable deployment across multiple entrances
Daily passenger flow demands unobstructed access in normal conditions
