Flood barriers and water control
Water is coming. I need it stopped in the next few hours.
Temporary barriers for flood defence, containment and dewatering — including the situations where a water-filled barrier cannot be used.
Most reusable flood barriers on the market are water-filled: you pump site water into a tube and the mass resists the flood. That is the cheapest answer for long runs along a river. It stops working at a shop doorway or a garage ramp where the flood has not arrived yet and there is no water to pump. Air-filled barriers deploy without a water source, which is the whole reason to pay more for them.
Типовые сценарии
- Shopfront and doorway defence during floods
- Underground garage and basement entrances
- Construction dewatering
- Oil spill containment
- Temporary cofferdams for water works
- Typhoon and storm preparation
Where this is the wrong purchase
For long continuous runs along a river or around a dewatering site with water available, water-filled barriers cost less per metre and are more stable because mass is free. Water pressure also rises with the square of height, so barrier height is a structural question — we will not quote a height without data behind it, and neither should anyone else.

Частые вопросы
- 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.
