What stops floodwater

the quickest and easiest?


water-filled barriers

The RapidH2O flood defence system benefits from a rigid frame, which gives it strong resistance against floating or flying objects, and lightweight tanks filled with water, which is readily available in copious amounts during flooding.

Its design allows it to be installed even where other systems stand no chance – in flooded areas or during flash floods. The high mobility, ease of deployment and versatility of RapidH2O barriers is ideal for both professionals and untrained users, who can handle its installation with only a pump even in harsh conditions and without special tools or heavy lifting equipment.

Product description

It looks like a gabion basket, but it isn't one. First of all, we use Zn‑Al galvanized steel instead of hot‑dip galvanized steel, which greatly prolongs the service life during repeated use. The dimensions are different from gabions, too. Why? For one thing, gabion baskets can be made of thinner wire. The wire we use is 4 mm thick. With a mesh size of 5 × 5 cm, our barriers would be much heavier and harder to handle. Conversely, a 10 × 10‑cm mesh would be much lighter, but its strength would not have the required parameters and the protection of the tank against external damage would be much weaker. We use a mesh size precisely defined by the number of wires per m2 of surface area, 14 × 14 wires being exactly the sweetspot providing an acceptable barrier weight together with great durability and stability.

The tanks that are inserted into each cage are made of a multi‑layer polymer that is UV‑stable and, unlike rubber materials, requires only minimal maintenance during longer‑term storage. The tanks are easy to clean with pressure water and can easily be turned inside out if necessary. Another advantage is that no valve is needed to fill or drain the barrier. To empty the tank, just push one side of it to the ground (e.g. using a broomstick), and the water will flow over the edge.

Apply for your
free training session

In order for you to get a better understanding of our Flood Barriers, we are prepared to bring a section along to your chosen place for us to give a no obligation/cost demonstration-training session. Once you have had the opportunity to observe and take part it will become very clear to you the financial and practical advantages associated with using RapidH2O Flood Barriers.

100 m

A RapidH2O barrier 100 m long and 1 m tall can be built by 4 people using 2 pumps of adequate power in only 2 hours. Anyone having the experience with filling sandbags will agree that not even a hundred people can build a barrier half as long in two hours. And this requires having enough sand at hand.

Dismantling such a RapidH2O barrier will take half an hour less in the same number of people (i.e. approximately 90 minutes). No laborious tidying and removal of sand is necessary.

deployment of rapidh2o

Unfold the five‑cell barrier and lock cages together as needed using connecting wires.

Line the RapidH2O tanks with the cells of the barrier frame and secure them in place using zip ties.

Repeat this process until all tanks are properly deployed and fastened.

Use a pump to fill the barrier. The quality of the water does not matter.

Dismantling of rapidh2o

Remove all zip ties to detach the tanks from the cages.

Push in one corner of the tank to allow the water to escape.

Gradually empty all tanks in the barrier.

Remove empty tanks from cages for storage and future reuse.

Filled with water without any requirements for its quality

Rapid deployment

Easy handling

Long-lasting reusability

Easy to empty and dismantle

Undemanding on storage conditions

Superb cost‑effectiveness

Optional reinforcement
with ribs

Your barrier will be fixable even if you run it over with a lorry, and if you still somehow manage to destroy it, we will supply you with a new one for free (this does not apply to damage caused by vandalism).
