Pop Up Flood Barriers

March 1, 2022
DENIOS' flood barriers automatically “pop up” when liquid enters the built-in collection sump.

The passive Pop Up Flood Barriers automatically engage at the first flow of water, protecting buildings and their contents from damaging floods and spills. The FM Approved design requires no external power source or compressed air supply.


The flexible design allows installation on the inside or outside of exterior doors. Barriers are built specifically for the doorways they protect, with sizes from 3 to 12 ft (0.9 to 3.7 m) wide and heights of 12 in. (304 mm), 18 in. (457 mm) or 24 in. (610 mm) tall.


It is constructed of solid welded stainless steel for chemical resistance and long service life. This self-contained one-piece design is factory adjusted and lubricated and easily installs in existing doorways.


It automatically “pops up” when liquid enters the built-in collection sump, creating a liquid-tight seal that prevents the liquid from entering the doorway. There is no external sensor or human interaction required. After the event, the barriers can be reset and reused.


When not in use, it permits normal vehicular traffic by storing horizontally on the floor. The Pop Up Flood Barriers are NFPA, IFC, and OSHA approved.
