Flood DefendTM
Demountable Aluminum Flood Barrier China Manufacturer and Supplier
NewFlag manufactures modular demountable flood barriers for residential, commercial, industrial, and municipal flood protection. Lightweight aluminum panels can be installed quickly, stacked to the required height, and removed after the flood risk has passed. Custom sizes and system configurations are available for different openings and project requirements.
- Lightweight Aluminum Panels: Anodized aluminum panels are lightweight, corrosion-resistant, and easy to handle during installation.
- Strong Engineered Structure: The reinforced system provides reliable strength and stability against floodwater pressure.
- Adjustable Protection Height: Stackable barrier panels allow the flood defense height to be adjusted for different water levels.
- Demountable and Reusable: The panels and posts can be removed after use, helping preserve access and the surrounding landscape.
- Reliable Sealing System: EPDM seals on the posts and panels help minimize water seepage during flood events.
- No Continuous Ground Frame: The PE or PU bottom seal reduces the need for a permanent raised ground frame.
- Quick Installation and Removal: The modular system can be installed and dismantled quickly using simple everyday tools.
- Single Spans up to 6,000 mm: A single barrier section can cover openings up to 6,000 mm, subject to project design requirements.

Benefits of Demountable Aluminum Flood Barrier
Demountable aluminum flood barriers are designed for rapid installation when a flood warning is issued. With key components prepared or pre-installed in advance, a small team can quickly insert and stack the removable panels to create a continuous temporary flood barrier.
Manufactured from 6005 and 6063 aluminum alloys, the system combines structural strength with low weight and easy handling. Each standard 200 mm-high panel weighs approximately 2.4 kg per linear meter, allowing it to be carried and installed by one person without heavy lifting equipment.
The panels can be stacked to provide different flood protection heights within the system’s design limits. Once the flood risk has passed, the removable components can be dismantled using standard tools, leaving only minimal permanent structures and reducing the visual impact on the surrounding area. The modular components are also compact and convenient to transport and store.
NewFlag Demountable Flood Barrier in Detail
Aluminum Posts
End posts and intermediate posts support the barrier panels and provide structural stability for the entire flood barrier system.
Barrier Panels
Lightweight aluminum panels slide into the post channels and can be stacked to achieve the required flood protection height.
Watertight Panel System
Interlocking aluminum panels and integrated seals help minimize water seepage under flood conditions.
Compression Devices
Mechanical compression devices press the stacked panels firmly against the bottom seal to improve sealing performance.
Seals and Gaskets
Durable rubber seals between the panels, posts, and base surface help reduce water seepage and maintain reliable sealing.
Reusable and Easy to Store
The removable components can be dismantled, organized on storage racks, and reused for future flood protection.
Applications of Demountable Flood Barrier
- Residential Properties: Installed across driveways, garage entrances, doors, gates, and basement access points to help protect homes from rising floodwater.
- Commercial Buildings: Used at shopping centers, hotels, office buildings, warehouses, and retail stores where entrances must remain open during normal operation.
- Industrial Facilities: Suitable for factories, workshops, power stations, storage areas, and equipment rooms that require protection from water damage and production disruption.
- Underground Entrances: Applied at underground parking entrances, tunnels, subway access points, and basement ramps where floodwater can enter quickly.
- Municipal Infrastructure: Used around public buildings, hospitals, schools, transport facilities, and emergency service centers to support urban flood protection plans.
- Riverside and Coastal Areas: Installed in locations exposed to river flooding, storm surges, heavy rainfall, or seasonal high-water events.
- Utilities and Critical Equipment: Protects electrical rooms, pump stations, data centers, communication facilities, and other critical infrastructure where water intrusion could cause serious operational losses.
FAQ
What is a demountable flood barrier?
A demountable flood barrier is a removable flood protection system made from posts, stackable panels, seals, and fixing components. It is installed when flooding is expected and removed for storage when no longer required.
How does a demountable flood barrier work?
The posts are secured to prepared fixing points, and aluminum panels are inserted and stacked between them. Compression devices and sealing strips create pressure between the panels, posts, and base surface to minimize water seepage.
in what situations should a demountable flood barrier be used?
Seasonal Flood Protection
Suitable for locations exposed to seasonal flooding that require reliable protection only during high-risk periods. The barrier can be installed when needed and removed afterward.
Emergency Flood Defense
Ideal for sites facing sudden or unpredictable flood risks. Modular components can be deployed quickly to protect entrances, roads, facilities, and other vulnerable areas.
Space-Sensitive Locations
A practical choice where permanent flood walls would restrict access, occupy valuable space, or affect the surrounding appearance. The system can be removed when flood protection is not required.
Existing Buildings and Infrastructure
Suitable for retrofitting commercial buildings, factories, transport facilities, and public infrastructure without extensive structural modifications.
Urban and High-Traffic Areas
Can protect streets, underground entrances, public buildings, and critical infrastructure while allowing normal access and daily operations outside flood events.
Sites Requiring Reusable Protection
Well suited to locations that need flood protection across multiple events. The removable panels and posts can be stored and reused, helping reduce long-term protection costs.
Where can demountable flood barriers be installed?
They can protect building entrances, factory gates, underground parking entrances, roads, subway entrances, waterfront facilities, commercial properties, and other locations exposed to flood risks.
What materials are used to manufacture the barriers?
Most demountable systems use lightweight aluminum alloy panels and posts, together with corrosion-resistant fixings and durable rubber or EPDM seals. Exact materials should be selected according to the required strength, environment, and service conditions.
Can demountable flood barriers be reused?
Yes. The aluminum posts and panels are designed for repeated deployment. After each use, the components should be cleaned, inspected, dried, and stored properly. Damaged seals or fixings should be replaced before the next installation.
