Floody Temporary Flood Barriers
Description

The Floody barrier system is a lightweight, modular, temporary flood barrier that quickly snaps together to divert floodwater and protect property without the need for sandbags or permanent installation. It uses the weight of water to self-anchor and a sealed base to minimise leakage, allowing rapid deployment and removal when flood risk passes.

Key Features
  • Hydrostatic self-anchoring: Stability increases with water depth as lateral load drives the barrier into the ground, eliminating the need for mechanical fixings in most scenarios.
  • Low leakage interface: Continuous base seal and interlocking joints minimise bypass flow compared to discontinuous systems like sandbags.
  • Rapid deployment rate: Modular sections with tool-free connections enable fast installation rates with minimal labour.
  • Reusable system: Durable plastic construction allows repeated deployment cycles without degradation typical of sandbag systems.
  • Lightweight logistics: Low unit weight improves manual handling, transport efficiency, and reduces H&S risk during installation.
  • Scalable and adaptable: System can be extended, curved, or reconfigured to suit varying site geometries and protection lengths.
  • Reduced site disturbance: No excavation or permanent works required, preserving existing surfaces and enabling use on finished assets.

Scope of Use

Floody is best suited to temporary flood protection scenarios where the objective is to manage overland flow, sheet flow, or ponding. It is most effective for protecting doorways, garages, minor dwellings, and low-lying building perimeters, as well as diverting water away from accessways and critical services. The system is appropriate across residential, light commercial, and construction environments, particularly where permanent works are impractical or unnecessary, and where a rapid deployment and removal approach is preferred.

The system performs best on hard, smooth, and continuous surfaces such as concrete or asphalt, where the base seal can engage properly and limit leakage. Floody is well suited to long protection runs and repeated use.

Limitations on Use

While stainless steel end units enable effective sealing against walls, overall performance still depends on a smooth, continuous surface and proper installation to minimise leakage and bypass.

In-Service History

Internationally, products like Floody have been used since 1997, originating in Finland and going global around 2007 they have been protecting properties around the world from flood damage. Also useful for service providers to divert water, provide a dry work area, or temporary above ground reservoir.

Other Performance Attributes

Floody barriers can be permanently bolted down to prevent unauthorised movement if required.
