Portal Flex Gates

What is it?

High-strength Portal Flex Gates (PFG’s) can be deployed rapidly for flood protection of tunnels, vehicular entrances, doors or portals of any kind; can fit openings of any simple shape, size or orientation; simple to operate and can be easily deployed or retracted like a garage door, in a few minutes (powered or manually), by a single person with very little training; scalable to very large openings and water heights in excess of 30 feet; few moving parts, resulting in increased reliability, with minimal maintenance.

Project Phase?

  • Emergency

Implementation Time?

Less than an hour

Useful Life?

Approximately 25 years with proper maintenance

Preliminary Costs?

 $$$$

The initial installation cost varies based on application and size of the portal and can be substantial. However, the PFG cost is competitive with comparable systems, such as a more traditional watertight door: approximately $200-250k per system.

Benefits

  • Point-of-use storage - no lost components or off-site storage

  • Rapid deployment

  • Operations resume faster

  • "Scalable" design - sized to fit multiple openings

  • Robust materials and construction - withstands debris impacts

  • Compact storage - stores in small spaces

Limiting Factors

  • Adequate overhead, side, and floor space is required for installation

  • Requires simple portal geometries without obtrusion

  • Continuous conduits or openings outside the portal frame (such as a trench drain) are incompatible with the PFG without special detailing

  • Proprietary nature of the system can be a limitations should replacement parts be required
