Flooding poses significant risks to both civilian properties and water management infrastructure. Installing a reliable flood protection system is essential for mitigating these risks. The NF-35 Demountable Flood Barrier System by NEWFLAG offers a robust, lightweight, and easily deployable solution designed to safeguard against flood heights of up to 1.4 meters. This guide walks you through the step-by-step installation of this innovative flood protection system, ensuring optimal performance and durability.

Step 1: Prepare the Foundation

The NF-35 flood barrier requires a pre-installed concrete foundation for the anchor plates. These plates are essential to secure the system’s strength and stability when fighting against high water levels.

• Mark the Installation Area: Identify and clear the area where the barrier will be installed. Ensure the foundation is smooth and level.
• Embed the Anchor Plates: Install the anchor plates into the concrete foundation at the designated points. Allow sufficient curing time for the concrete to ensure a secure base.

Step 2: Install Permanent Components

The permanent parts of the system include end posts, side posts, and pre-installed anchor plates.

• Position End Posts: Align the end posts at the boundaries of the flood protection area. Ensure they are level and securely bolted to the anchor plates.
• Check Alignment: Use a level to confirm that all permanent components are properly aligned, as this will affect the sealing and effectiveness of the flood barrier.

Step 3: Deploy Central Posts and Stackable Panels

Once a flood warning is received, the barrier can be quickly deployed with a team of 3–4 workers.

• Bolt Central Posts: Attach the central posts to the pre-installed anchor plates. These posts serve as the structural supports for the barrier panels.
• Insert Barrier Panels (Stop Logs): Slide the removable and stackable panels into the recesses of the posts. Adjust the height of the panels according to the required flood protection, from 200mm up to 1400mm.

Step 4: Ensure Water Tightness

Waterproofing is a critical element of any flood protection system.

• Ground Seals: The NF-35 flood barrier uses PU & PE ground seals to compensate for uneven ground surfaces, ensuring a secure fit.
• EPDM Rubber Seals: These seals in both the posts and panels provide excellent watertightness. Tighten the system by installing the pressing tool on top of the barrier to enhance the seal.

Step 5: Test the System

Before the flood arrives, it is essential to test the installation to ensure it is fully functional.

• Inspect Seals: Check all seals for any gaps or misalignments.
• Verify Structural Stability: Ensure that the posts and panels are securely fastened and stable.
• Simulate Flood Conditions: If possible, simulate a low-level water flow to confirm the barrier’s performance.

Step 6: Dismantle and Store

After the flood has subsided, the NF-35 system can be easily disassembled and stored for future use.

• Remove Panels: Carefully slide out the stackable panels and disassemble the central posts.
• Clean and Store: Clean all components to prevent corrosion and store them in a dry, secure location for the next deployment.

Key Advantages of the NF-35 Demountable Flood Barrier

• Adjustable Height: Accommodates flood heights from 200mm to 1400mm.
• Rapid Deployment: A team of 3–4 workers can set up the barrier quickly.
• No Visual Impact: When not in use, the system leaves no noticeable footprint.
• Lightweight Design: Easy to handle and install, yet offers extraordinary flood resistance.
• Durable and Reliable: PU & PE seals and EPDM rubber components ensure long-lasting performance.
