Mobile flood protection
Five people build 100 meters of protective line with the Beaver in about an hour. For the same line built from sandbags, the manufacturer estimates 20 people, 6,500 bags and five hours. The water carries the load, your crews stay fit for duty.

Your crews
A sandbag dam is filled, lifted, passed along and stacked bag by bag. With the Beaver, a few responders roll out the elements, connect them and let the pump do the work. Everyone else stays free for whatever needs hands at the incident.
Comparison based on the manufacturer's brochure from Beaver Schutzsysteme AG, Grosswangen (CH).
Five people build 100 meters. For the same line built from sandbags, the manufacturer estimates twenty.
A 20 m element of the M2 50 weighs about 110 kg empty and is carried as a team. The pump delivers the roughly 600 liters of water per meter.
Sandbag chains need many people who have to be relieved regularly, according to the Baden-Württemberg state fire academy. With the Beaver, a small team is enough.
Anyone not shoveling sand is ready for rescuing people, pumping and securing the area. During the day in particular, this counts double for volunteer fire departments.
Drain the water, dry, roll up. Instead of tons of wet sand, the dam goes back into storage.

We plan for terrain, connections to walls and changes of direction with you during the site visit.
How the line goes up
No heavy equipment, no loose parts. The elements come rolled up off the trailer and are set up in a few steps.
Roll out the rolled-up element along the planned protective line. It follows the terrain, and changes of direction need no special parts.
Fill both chambers with air first. This gives the dam its shape and makes it easy to push into its final position.
Attach further elements via the offset sleeve ends. The connection is watertight and transfers the load, and the protective line can be any length.
Fill with water from a hydrant or open water via the Storz 55 connections, and the floodwater already on site can be used too. The weight of the water holds the dam in place.
After the deployment, the water drains out through the patented drainage system. Dry, roll up, store: the Beaver can be reused many times and takes up little space in storage.
Request a quoteProcedure according to the manufacturer's specifications. Documented example: 6 to 8 people build 320 m of protective line with 50 cm damming height in 90 minutes.
Swiss engineering
Each element consists of two parallel, firmly connected chambers. This design holds the dam in position against water pressure and cross slope, without any anchors, nets or extra parts.
A single tube would roll away under water pressure or on a cross slope. Two firmly connected chambers lie wide and heavy on the ground.
The ends of the two chambers are offset from each other. This lets the elements interlock, and the connection stays tight and transfers the load.
Standardized connection for the fire hose on all types. Filling is from a hydrant, open water or with the floodwater on site.
The water drains off in a controlled way through the clamp plate after the deployment. Patent granted. From the M2 50 upward, every element has two.
Coated with PVC on both sides, 900 g/m², tensile strength 4,300 / 4,000 N per 5 cm, temperature-resistant from −40 to +70 °C.

The Beaver family
All types are laid, connected and filled the same way. The cross sections are shown to the same scale, next to a person 1.80 m tall. Dashed: the top element for extra height.

Manufacturer's data (brochure and list of pack sizes and weights 08/2025), all values approximate. Raising the height with a top element is an emergency measure: the design damming height remains that of the double element.

+49 1522 8790057 sales@rescuevation.comRequest a quoteAccording to the manufacturer, 5 people build 100 m of protective line with 80 cm damming height in about one hour, including filling. A documented example: 6 to 8 people set up 320 m with 50 cm damming height in 90 minutes. The actual time depends on type, terrain, personnel and water source.
From a hydrant or a nearby body of water, pumped through the Storz 55 fill inlets. The floodwater on site can also be used. An M2 50 needs about 600 liters per meter.
No mobile emergency flood protection system is completely watertight. The accepted leakage rate is 2 to 3 liters per minute per linear meter. In practice, the Beaver usually stays well below that, sandbag dams usually above it (manufacturer's data).
The wide footprint of the twin-chamber system gives the dam high stability. How securely it stands depends on the ground, cross slope and current, so you plan for freeboard and reserve damming height. On loose gravel, snow or ice and on a steep cross slope, sliding resistance decreases; sandbags placed on the land side increase it.
Yes. The dam adapts to the terrain and works on slopes of up to about 10 degrees. Changes of direction are possible at any point and in both directions, without special elements.
Yes, with a third element placed on top, depending on the type up to 45 cm (P2 30) and up to 190 cm (S2 130). This is an emergency measure when overtopping is imminent: stability against tipping and sliding decreases, and the design damming height remains that of the double element.
A single tube would roll away under water pressure or on a cross slope. Two firmly connected chambers with offset ends interlock, transfer the load and give the dam its stability.
Clean and dry inside and out, with closures fitted and shut, at −30 °C to +70 °C. The stacking height is at most 120 to 150 cm so that no creases form. Rolled up, the elements are stored compactly and without loose parts.
The manufacturer describes it as ready for use for decades and reusable many times. A repair kit is available for repairs, and equipment technicians learn how to carry them out in a dedicated course.
Yes. Municipalities, fire departments and authorities order from us on account. Request your quote directly using the form.
The elements are delivered by freight carrier. We set the delivery date, instruction and, on request, dry and wet training directly in your quote.
No mobile flood protection system is 100% safe. Correctly sized and set up, the Beaver has proven itself in over 1,000 real deployments. We work out the sizing with you on site.
