How it unfolds

Three stages, one concept.

A severe weather incident follows a clear sequence: prepare, defend, recover. Scroll through the stages and see at once what your phase needs and what is missing for the next one.

Responders setting up a Beaver tube dam
Coswig, 2021

Stage 01

Prepare before the water arrives

If the flooding is foreseeable a few hours in advance, the Beaver tube dam plays to its strengths: a small team lays around 100 meters of protective line per hour, without heavy equipment, even on uneven ground. Where the surface is level and firm, the Flood Fence closes off corners and short sections.

What must be settled in this phase

  • Define the route and length of the protective line
  • Determine the damming height needed per section
  • Weigh setup time and personnel needs against the warning time
  • Plan for transport, storage space and re-stowing the barrier

Stage 02

Defend: openings and danger points sealed

The Lenoir® barriers respond even in the middle of the storm: roll out, position, and the oncoming water raises them and presses them onto the ground. This lets you seal factory gates and protect underground garages in seconds. For oil, chemicals and contaminated firewater, the same technology comes in an antistatic version.

What must be settled in this phase

  • Record every opening in the protected area: doors, gates, shafts, inlets
  • Document each opening's dimensions: they decide the right barrier
  • Define which access points must stay passable during the response
  • Treat hazmat storage, drains and sewer inlets separately

Stage 03

Recover: water out, surfaces clear

If water has come over after all, you have the right equipment to pump out basements quickly, push the water off and clean the roads. And because incidents like these take time, sanitation is part of the concept.

What must be settled in this phase

  • Residual water that pumps can no longer remove
  • Squeegee surfaces, stairs and hall floors and make them walkable
  • Plan for deployments beyond 24 hours: hygiene and crew care
  • Clear roadways and paved surfaces of mud and flood debris
  • Plan for cleaning, drying and re-stowing the equipment

The systems

Four systems, one principle.

All four use the very water they are meant to hold back. Here you can see how each system works, what damming height it achieves and what it is made for.

How it works

Heavy rain response in seconds

Lenoir® Water Barrier

Roll out, position, done. The oncoming water flows onto the lower leg, fills the flap barrier and raises the retaining wall by itself. The weight of the water presses it onto the ground: the higher the flood, the more stable it stands. No pump, no generator, no setup team.

  • 2 responders are enough
  • Adapts to asphalt, paving, grass and slopes
  • Connects into protective lines of any length
  • Developed and made in Switzerland

Taking the load off

Less hauling. Less damage.

Every hour your crews don't spend on sand and bags is available for the actual incident. And every opening sealed in time keeps water out of basements, underground garages, building services and the sewer.

Sandbags

  • Filling, hauling, stacking: ties up many responders for hours
  • Contaminated after the incident and must be disposed of as hazardous waste
  • Large stockpiles, resupply and disposal logistics
  • Slow to set up when the warning time is short

approx. 690 € per linear meter of sandbag protection (benchmark)

Disposal as hazardous waste, around 70%Sand, bags and logistics, around 30%

Mobile system

  • Beaver: around 100 m of protective line per hour with a small team, without heavy equipment
  • Lenoir®: rolled out in seconds, the water raises the barrier by itself
  • Clean, roll up, reuse: no hazardous waste
  • Stored compactly: the heavy rain protection fits in a box

Manufacturer's figures: Beaver around 100 m per hour with a small team, Lenoir® with 2 responders per element.

What you protect in time

  • Garages and driveways Ramps and entrances sealed before the water runs down below.
  • Basements & utilities Heating, electrics and storage stay dry when the openings are secured in time.
  • Businesses and hazmat storage Secure factory gates and keep oil, chemicals or contaminated firewater out of sewers and watercourses.
  • Towns and streets Long protective lines along banks and streets, even on uneven ground.

How we calculate

Sandbags: Bags and time needed per meter of dam according to the Baden-Württemberg state fire academy, guidance on using sandbags in floods (2014, based on Akademie Hochwasserschutz): 0.5 m height 40 bags and 3 minutes with 10 helpers, 1 m height 120 bags and 9 minutes. Linear in between, below that calculated with the square of the height.

  • Bag filled 2/3: 18 kg (source: 18 to 20 kg)
  • Pallet: 70 bags, 1.2 to 1.4 t
  • Truck: 16 t class tipper with at most 8 t payload
  • Filling: 80 bags per helper hour (10 helpers with filling aids manage 800 bags per hour)
  • Energy: shoveling 6.5 MET, carrying heavy loads 8.0 MET, laying out the barrier 4.5 MET (Compendium of Physical Activities), body weight 80 kg
  • Bratwurst: 100 g at around 280 kcal
  • Lenoir®: elements from the available lengths, laying time from the EVH test values, two responders

In practice, transport to the incident scene, sourcing the sand and dismantling come on top of this.

1 · Banks and dikes

Long lines along banks and dikes

When a river overflows its banks, it's line length that counts. The Beaver tube dam fights water with water: the twin-chamber system is filled with water, lies flat and heavy on the ground and can be extended seamlessly into long protective lines, with changes of direction at any point.

  • Around 100 m per hour with a small team, without heavy equipment
  • Five types from 30 to 130 cm damming height
  • Also on uneven ground and slopes up to 10°
  • Withstands current and flood debris

FAQs

What fire departments and municipalities ask

Didn't find your question? We reply within 24 hours.

When do I use the Beaver tube dam, and when the Lenoir® Water Barrier?

The Lenoir® Water Barrier is made for a fast response and flexible short runs: roll it out, position it, and the oncoming water raises it. The Beaver tube dam is for long protective lines and high damming heights up to approx. 130 cm. With a short warning time, the Lenoir is up fastest. For level, firm surfaces up to 45 cm damming height, there is also the Beaver Flood Fence, which is set up tool-free.

What does mobile flood protection cost?

We size the tube dam and Lenoir barriers according to protective line, damming height and equipment. You get a quote with line items and delivery time. The Beaver Flood Fence is ready to order, with the straight base element from 201.11 € net. For comparison: as a benchmark, one linear meter of sandbag protection costs around 690 € including setup, material and disposal, around 70% of which is for disposal as hazardous waste.

How fast is a protective line up?

A small team sets up the Beaver tube dam at around 100 meters per hour, without heavy equipment. How long it takes in each case depends on type, length, personnel, terrain and available water volume. 2 responders roll out the Lenoir® Water Barrier in seconds, and the oncoming water does the rest.

Is mobile flood protection watertight?

No mobile emergency flood protection system is completely watertight. Internationally, a leakage rate of 2 to 3 liters per minute per linear meter is accepted. In practice, the Beaver tube dam usually stays well below that. Whatever seeps through, you take up with a submersible pump and the Wasserschlucker.

Are the systems tested?

Yes. The Beaver tube dam and Lenoir® Water Barrier are EVH-certified (Europaverband Hochwasserschutz e. V.). Over 1,400 Lenoir barriers are in use across Europe, and over 150 km of the Beaver system are in the field. You can get documentation for your procurement on request.

Can fire departments and municipalities purchase on account?

Yes. Municipalities, fire departments and emergency services can purchase on account, with XRechnung and compliant PDF invoices included. You get a quote with line items and delivery time that you can use to register the procurement in your budget.

Do you offer site surveys and on-site briefings?

Yes. We analyze the hazard and ground right at the property and size your system, from protective lines to building protection. On request with briefing and wet drills for your crews, right at your site.

How are the systems stored and looked after following an incident?

After the incident, drain the water, clean, dry and roll up: the systems are reusable and produce no hazardous waste like soaked sandbags. The Beaver tube dam is rolled up compactly and stored dry at −30 °C to +70 °C. The Lenoir® Water Barrier lies rolled flat in a box, a 10 m element from 30 cm roll diameter.
