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.

Garage Flood Gate

地下车库挡水

A compact inflatable barrier made for the entrance of an underground car park or basement.

garage flood gate — product view on a plain background — Изделие

garage flood gate deployed on site, in use — На объекте

Типовые сценарии

Underground car park ramps facing ingress
Metro and basement retail entrances
Plant room door openings
Standing flood provision held by building management

Почему пневмокаркасная конструкция

Stores in a cupboard and deploys in minutes by one person
Reusable season after season
Sized to the opening rather than improvised

Когда это не подходит

Retained height has a hard limit and sealing depends on the opening being flat and sound. An uneven or damaged threshold must be made good first, or the barrier will leak past rather than hold.

Параметры уточняются у производителя
