Water-activated expandable flood barrier that inflates to 3.5 inches high when wet — creating a continuous seal across doorways and garage openings. The 10-foot kit protects a standard 9-foot garage door opening with overlap for corners. Unlike rigid aluminum barriers, PortaBarrier conforms to uneven floor surfaces and eliminates the need for precise leveling. Reusable — dry out completely and repack for storage.
