Understanding TubeBarrier: Self-Filling Flood Protection

TubeBarrier is a rapidly deployable, self-filling temporary flood barrier that uses hydrostatic pressure to anchor itself to the ground. Unlike traditional sandbags or powered solutions, TubeBarrier requires no pumps, power, or extensive labour. Its modular design allows for quick deployment and re-use, making it a cost-effective and sustainable alternative for flood protection.

The Science Behind TubeBarrier

TubeBarrier’s effectiveness lies in its simple yet ingenious design. The barrier consists of interconnected chambers that fill with water via intake valves. As the chambers fill, the hydrostatic pressure increases, creating a strong downward force that anchors the barrier to the ground. This self-filling and self-stabilising mechanism ensures consistent performance, even on uneven surfaces.

• Hydrostatic Anchoring: The weight of the water inside the chambers provides a secure anchor, preventing uplift and displacement.
• Self-Filling: Intake valves allow water to enter the chambers automatically, eliminating the need for pumps or external power sources.
• Modular Design: 10-metre modules can be easily connected to create a continuous barrier of any desired length.

Rapid and Efficient Installation

TubeBarrier is designed for rapid deployment, minimising the time and resources required for installation. A trained four-person crew can deploy up to 100 metres of barrier per hour.

1. Site Preparation: Clear the deployment area of any sharp objects and mark the desired line of defence. No ground works are required.
2. Unfolding Modules: The 10-metre modules unfold like an accordion along the planned defence line. Each module weighs approximately 75 kg when empty, allowing for easy handling.
3. Watertight Connection: Sturdy zips with sealing flaps create a continuous, watertight barrier between modules.
4. Intake Valve Alignment: Position the intake valves to face the incoming floodwater. This allows the chambers to fill automatically as the water level rises.
5. Self-Filling and Anchoring: As the floodwater rises, the chambers fill, and the barrier anchors itself to the ground.
6. Monitoring: Regularly check the junctions between modules and any transitions (e.g., kerbs, ramps) to ensure a secure seal.
7. Draining and Storage: After the flood event, open the drain valves to empty the chambers. Allow the modules to dry completely before folding them for compact storage and reuse.

Optional Pre-Stabilisation: If floodwater has not yet arrived, the barrier can be pre-stabilised by filling the chambers with hoses.

Rigorous Testing and Certification

TubeBarrier has undergone extensive testing at independent laboratories, including Flood Proof Holland and TU Delft, to ensure its performance and reliability. These tests have evaluated the barrier’s stability under hydrostatic loads, current, uneven ground conditions, and debris impact. The EU BRIGAID project has also assessed TubeBarrier’s readiness and impact.

Key performance indicators include:

• Stability: TubeBarrier remains stable and secure even under significant hydrostatic pressure and current.
• Watertightness: The modular connections provide a reliable watertight seal, preventing leakage.
• Durability: The barrier is constructed from robust materials that can withstand harsh environmental conditions and repeated use.

Protecting a Wide Range of Assets

TubeBarrier’s versatility makes it suitable for a wide range of applications, including:

• Municipalities: Protecting historic centres, subway entrances, tunnels, and utilities from flooding.
• Industry: Safeguarding warehouses, data centres, refineries, construction sites, and substations.
• Emergency Services: Providing rapid response to flash floods and river peaks.
• Residential and Commercial Properties: Protecting homes, hotels, basements, shops, ramps, and driveways.

TubeBarrier can be deployed in various environments, including urban areas, industrial sites, and residential neighbourhoods.

TubeBarrier vs. Traditional Methods

TubeBarrier offers significant advantages over traditional flood protection methods, such as sandbags and pumped tubes.

Sandbags: While sandbags are a common solution, they are labour-intensive to fill, transport, and deploy. They also create contaminated waste after a flood event. 10 metres of TubeBarrier replaces approximately 670 sandbags, significantly reducing labour and waste disposal costs.

Pumped Tubes: Pumped tubes reduce labour compared to sandbags, but they rely on external power sources and pumps, which can be unreliable during a flood. TubeBarrier is self-filling and requires no external power, making it a more resilient solution.

Economic and Environmental Benefits

TubeBarrier offers a compelling return on investment (ROI) and contributes to environmental sustainability.

Reduced Lifecycle Costs: The reusability of TubeBarrier over decades significantly lowers the cost per operation compared to sandbags. This includes savings on material procurement, transportation, labour, and waste disposal.
