The Hammerhead™ aluminum flood barrier system is a durable, stackable stop-log solution designed to protect doorways, entrances and other openings from flooding. The system has been tested and is FM 2510 / ASCE 2510 approved.
U-Channel posts are permanently installed on either side of the opening to be protected. When flooding is expected, aluminum planks are inserted into the posts and stacked to the required protection height.
The Hammerhead™ flood barrier is designed to withstand significant water pressure while helping protect residential, commercial and industrial properties from a wide range of flooding conditions. Its rigid construction also makes it suitable for areas where high winds or debris may be expected.
The system features the patent-pending SureGasket™ and AlumiSeal™ enhanced sealing technologies, designed to improve leak protection and provide a reliable barrier against water infiltration.
When reliable flood protection is required, the Hammerhead™ aluminum flood plank barrier provides a practical solution for residential and commercial properties.
Hammerhead™ aluminum flood barriers use a series of aluminum planks, or “logs”, that slide into support posts installed on either side of the opening being protected. Depending on the installation environment and site requirements, the mounting bolts can face either towards or away from the water.
The planks feature Rubber EPDM seals on their underside, while the support posts incorporate Rubber EPDM sealing material within the channels. Together, these components help create a durable seal against water infiltration.
For additional resistance against floodwater, wind and debris, the planks are tightened against the internal seals and secured from the top. This helps keep the flood barrier firmly positioned during severe conditions.
As floodwater rises, increasing hydrostatic and hydrodynamic pressure helps enhance the sealing effect of the barrier.
Choose between inside- or outside-mounted posts depending on your installation environment. Factors such as threshold construction, window or door configuration, wall construction and aesthetic requirements can influence the preferred mounting arrangement. Corner or centre posts can also be added where required.
Hammerhead® flood barriers incorporate the patent-pending SureGasket™ sealing system, designed to improve the connection between the post, bottom plank and ground. The engineered gasket design helps address potential leakage at the intersection between these components and provides enhanced sealing where it is most important.
For applications requiring enhanced flood protection, the AlumiSeal™ aluminum plate extrusion is designed to improve the seal between the Hammerhead® bottom plank, sill plate and ground surface.
The arced aluminum extrusion aligns with the bottom plank seal and works with the closed-bottom SureGasket™ configuration to provide an advanced leak protection system.
For improved aesthetics, powder coating can be added to the Hammerhead™ flood barrier system. Four standard colour options are available, helping the post mounts blend more effectively with the surrounding structure.
