The Best Floodgate Solution For 2023

When looking for an aluminum floodgate system it is important to find a flood control system that is significantly durable, easy to use, and fits your desired protection area.


As 2023 continues, the changing landscape of our world’s climate is causing more frequent and severe storms all throughout the calendar year. Therefore, floodgate protection systems are a vital component in protecting entryways of all sizes from the devastating effects of flooding. These systems can range from small residential solutions, to large commercial and industrial applications.

One of the most obvious benefits of an aluminum floodgate protection system is the ability to withstand rising water levels as a result of heavy rain, storm surges and severe storms. The damage that properties and overall infrastructure can endure from flooding is significant. Just one inch of flood water can cost upwards of $10,000 in restoration expenses. Floodgates are designed to keep harmful flood water out and fortify entryways with as much protection as possible.

Floodgates can also help to protect against the type of flooding that promotes mold and mildew. When water enters a building, it often saturates floors, sheetrock walls, and wooden built-ins that can lead to mold and mildew growth, which can be harmful, difficult and expensive to remove. Residential homeowners, business owners and municipalities understand not only the expense of removing mold and mildew but also the amount of time cutting back sheetrock, removing floors and repairing flood damage can be.

Effective floodgate barrier systems can also help to combat flooding that occurs as a result of common sewer backups and back-flows, due to overwhelmed drainage systems. Sewer backups can be caused by a variety of factors, including heavy rainfall, clogging, shut down of citywide sewer outlets to prevent damage to infrastructure and aging and outdated drainage systems.

While many believe that the rainfall from severe storms is the ultimate culprit of potentially harmful floods, it is often that the backup of sewers and outdated drainage networks significantly contributes to the issue.


Here at Garrison™️ Flood Control we pride ourselves on providing complete solutions for all of your flood protection needs. When looking for an aluminum floodgate system in 2023 it is important to find a system that is significantly durable, easy to use, and fits your protection area. Therefore, the best floodgate solution available is the Hammerhead™ Aluminum Flood Plank System.


Best Floodgate Solution 2023: Hammerhead™ Flood Planks

Hammerhead™ Aluminum Flood Planks are the latest innovation in floodgate technology. This system utilizes U-Channel Posts that install on each side of the desired protected area. With Hammerhead™ you gain both durable protection and subtlety with the posts being unobtrusive to the existing entryway.

Our U-Channel Posts install permanently without ever needing to be removed or re-installed for protection. From there, whenever a flood threat arises, aluminum planks are easily inserted into the channel providing you with durable protection against rushing water.

Hammerhead™ provides stackability with numerous aluminum planks being added. This creates a stop-log floodgate barrier that is perfect for both residential and commercial properties.

Protect Entrances, Garages and Doorways From Flooding:

  • Perimeter Opening Protection

  • Doorways and Window Wells

  • Garages and Ramps

  • Basement Stairwells

  • Loading Docks


Hammerhead Floodgate Planks: How Much Protection?

Each aluminum plank that fits into the Hammerhead™ channel provides 8in of protection height. With the ability to add up to 10 individual aluminum planks in an installed channel, Hammerhead™ is able to provide up to 6.5ft of total flood protection height.

Entryway protection length is just as important as protection height with a floodgate system. Hammerhead™ planks can be made up to 12ft in length. However, with our innovative double support center posts, the protection length of Hammerhead is unlimited when implementing.

The Double Support Center Post:

These posts are used when the desired entryway of protection exceeds 13ft and requires additional support. By drilling the center post into the ground, our center posts can either be installed permanently or with the ability to be removable when not in use. Each center post comes with a buttress support bracket allowing for additional resistance to pressure from potential floods.

What Makes Hammerhead™️ Floodgate Standout?

While there are other options available that serve as a floodgate solution, the drawbacks of certain products are glaring. It is important when choosing the best floodgate to remember the most important factors. With Hammerhead™ you never have to worry about the following.

  • Simple Installation - Solutions are supposed to adequately remedy the issues you face. The last thing anyone wants to deal with when implementing flood protection is a painful installation process. With Hammerhead™ the amount of time and manual labor saved with easy to follow instructions is significant.

  • Rapid Deployment - Flooding is the most common natural disaster in the world. With that, the sudden nature in which flood threats can arrive on your doorstep creates a challenge. Your floodgate solution needs to be able to deploy at a moment’s notice. With the already installed U-Channel Posts, deployment is made easy by just sliding the aluminum flood planks into place.

  • Durable Flood Protection - Hammerhead™ U-Channel Posts and Planks are made with 6065 T-5 Aluminum and use a Rubber EPDM sealing material to ensure that this floodgate solution stands strong against incoming flood threats. Being able to withstand up to 6.5ft of flood water at any desirable length offers protection most other alternatives cannot provide.

Available alternatives sometimes utilize inflated rubber tubes to seal panels inside a doorway or thin metal brackets to hold panels in place. These solutions often do not provide ample protection or resistance against severe threats and are prone to failure. Meanwhile, the Hammerhead™ is built specifically to handle severe flooding and also to handle impact from debris, wind from storms, and rapid water flows.
