Hammerhead™ aluminum flood planks, custom-sized to your openings, built in the USA, and ready to deploy before the next storm.
Hammerhead is a stop-log flood barrier with permanent U-Channel posts mounted on either side of an opening, and rigid aluminum planks slide in and tighten down to create a watertight wall when a storm is coming. Between storms, the planks store compactly and the low-profile posts stay in place.
For protection above plank height, on larger openings, or around an entire perimeter, Flood Barrier Systems offers a full line of complementary products.
The best time to plan flood protection is before a storm is named. Hammerhead posts install once and stay in place, so when a warning is issued your planks slot in and tighten down in minutes, no scramble for sandbags, no last-minute contractors.
Waiting until a storm is in the forecast often means limited availability. Preparing in advance means you are protected the moment you need it.
