Garrison Flood Control, a leading manufacturer of engineered flood protection systems, is proud to announce that its Hammerhead® Aluminum Flood Plank System has officially earned FM Approval under FM 2510, the Examination Standard for Flood Mitigation Equipment. The certification confirms that the approved Hammerhead configurations have successfully met the applicable testing and performance requirements established by FM Approvals, an independent third-party product testing and certification organization.

On Monday, October 19th, 2026, Garrison Flood Control and the Pasco County Department of Emergency Management came together at Arthur F. Engle Memorial Park in Hudson, Florida, for a live Flood Protection Product Demonstration.

Choosing reliable residential flood barriers starts with understanding how water reaches your home. A barrier designed for a front door may not be suitable for a sloped driveway, while a system that redirects runoff may not seal a garage opening.

For homeowners comparing garage flood barriers, aluminum flood plank systems are worth considering because they combine rigid protection with removable components.

What are the top removable flood barriers for entryways? Three options from Garrison Flood Control are the Hammerhead™ Aluminum Flood Wall, YellowFIN™ Flood Panel, and MAKO™ Inflatable Flood Barrier.

Garrison's Hammerhead™ Aluminum Flood Plank System uses 6063-T6 aluminum with a yield strength of 145 MPa (roughly 21,000 psi). Independent Finite Element Analysis and Computational Fluid Dynamics studies by Predictive Engineering, sealed by licensed Professional Engineers, show peak stresses staying below that threshold across every configuration tested.

For homeowners, some of the easiest aluminum flood barrier systems to use are those that separate the initial professional installation from the deployment required before a flood. Once the permanent components are properly installed, the homeowner can put the removable flood protection in place when severe weather or rising water threatens.

The YellowFIN™ Flood Panel Barrier System from Garrison Flood Control is a direct-mount flood panel system that delivers engineered structural strength without permanently fixed vertical posts.
