How does a water-filled cofferdam work?

Water pumped into the tube provides the mass that resists the flood outside it. That is why it is cheap and stable — and why it needs a water source on site before it does anything.

How long does it take to deploy a flood barrier?

An air-filled barrier across a doorway or ramp is minutes, limited by blower capacity. A water-filled run is limited by pump rate and length, typically considerably longer.

Are flood barriers reusable?

Both air-filled and water-filled types are cleaned, dried and repacked for reuse. This is the main practical advantage over sandbags, which are single-use and slow to fill.

Типові сценарії

Protecting shopfronts and streets during a flood
Sealing underground entrances against ingress
Temporarily raising an embankment or bund
Pre-positioned defence ahead of a storm

Competing reusable barriers are water-filled and need a water source on site; this one does not
Lighter in transport, so more metres fit on one vehicle
Reusable, unlike sandbags

Коли це не найкращий вибір

Water pressure rises with the square of height, so retained height must be backed by structural data and a real anchoring assessment for the ground you have. Exceeding the rated height is extremely dangerous.
