Flooding through doorways is one of the most alarming threats to homes, businesses and buildings.
When floodwaters begin to seep under your door, they don’t just threaten the physical structure of your property, they invade your very space, creating a chaotic waterlogged disaster.
The door that is meant to protect you becomes the primary point of entry for this relentless force and many traditional methods like sandbags fail to provide the reliable seal needed to prevent the water from getting in.
Sandbags require immense effort to deploy and are often ineffective, leaving gaps that allow water to flow through the door and cause damage.
This is where the NoFloods AluGate shines as the ideal solution for protecting doorways from flooding.
Engineered for both residential and commercial use, the AluGate combines cutting-edge technology with an easy-to-use and adaptable design that ensures a secure watertight seal around doorways.
Available in two versatile models, the AluGate offers tailored solutions for different needs: the G Model for large-scale flood defences and the W Model for individual doors, windows and other entry points.
Here, we’ll focus mainly on the W model and explore why it’s the ultimate door flood barrier system, offering dependable long-term protection and peace of mind for property owners worldwide.

How to Install the AluGate Door Flood Protection System
Installing the NoFloods AluGate W model is designed to be quick, easy and efficient.
Step 1: Post Installation
- Position the posts: Ensure the rubber seals are facing the wall and the U-channel opening is directed toward the entryway where the planks will be inserted.
- Create holes for anchors: Use a hammer drill to create holes for the expanding wall anchors.
- Secure the posts: Insert and expand the anchors into the wall ensuring they are installed into solid concrete, cinderblock or cement for maximum stability.
Step 2: Connecting the Units
- Loosen bolts and top locking bracket: Before inserting the planks, ensure the tightening bolts and top locking bracket are loosened.
- Insert the planks: Place the planks with the rubber seals facing downwards into the U-channel of the posts. Continue adding planks until the entire section is in place. Make sure the plank with reflective warning tape is the last to be placed on top.
Step 3: Locking and Tightening
- Tighten planks: Use the Allen wrench to tighten the flood planks into position, ensuring they are pressed against the internal rubber seals to form a tight seal.
- Secure the top: Insert the top locking clamps into the post’s top slot. Tighten the clamps with the Allen wrench to apply pressure to the planks, enhancing the seal.
- Final adjustments: Tighten the bolts on the posts to secure the planks in the U-channel and ensure a perfect seal with the neoprene strips.
Step 4: Disassembly and Storage
- Loosen and remove planks: When flood protection is no longer needed, loosen the top locking clamps and tightening bolts and remove the planks in reverse order.
- Clean and store: Clean the system, dry it thoroughly and store it away until the next use. Ensure it is kept in a safe dry place to prolong its lifespan.
