Our barriers are the ideal tool to facilitate various military interventions, even in emergencies.

Forget sandbags

Floods affect and disrupt the entire planet, exposing thousands of victims to the risks of contamination, intoxication, electrocution and, of course, intense stress.

Used around the world, Water-Gate flood barriers are the perfect alternative to sandbags because they can replace thousands of sandbags in an instant. In addition, they remain stable, regardless of the length and direction of the flow, or the slope of the terrain. Water-Gate barriers can be put in place while the flood is already underway! This innovative and unprecedented intervention equipment combines simplicity, robustness and reliability.


Recognized worldwide for its reliability, solidity and ease of deployment, our WA model of the Water-Gate barrier is versatile and aimed at a selection of users as vast as it is diversified, such as the military. Constructed of super-resistant materials, this revolutionary response equipment benefits from unprecedented reliability and speed of execution. Water-Gate barriers are reusable, portable and ideal for emergency response even inside a stream, river or ditch.

Why use a water barrier?

Water-Gate offers different types of barriers that help fight floods, set up temporary water reserves or carry out aquatic works.

Flash flood

The Water-Gate flood barrier is easy to install and requires very little labour to deploy. Ideal for flash floods, sudden water level rises, downpours or any unforeseen event causing the flood. It provides instant protection.

Coastal Flood

The barrier can be installed directly along a bank to prevent overflows. The perfect response to coastal floods or phenomena such as rising sea levels.

Underflow Dam

The release holes have been added to the barrier to provide it with a function allowing the underflow of water while the pollutants float on the surface. Release holes can be closed and opened at any time.

Absorbent tubes can be installed along the barrier in order to absorb all the dangerous matter while the clear water continues its way in underflow. Water circulation is neither affected nor interrupted. Once filled, the absorbent tubes can be easily replaced. It is possible to attach them directly to the barrier.

Water Reserve

The water barrier is ideal for the rapid installation of a suction point facilitating the creation of a water reserve, especially during fires. This water, filtered from all debris and all impurities, can then be used to fight a fire or even a forest fire. Given the portable nature of the barrier, it is no longer necessary to stand near a fire hydrant to recharge your batteries in water.

Chemical Spills

While this use is recommended for our WT models, the WA model has dual functionality to contain a toxic spill. However, only the overflow function is made possible in the absence of a release hole downstream of the barrier. As with the WT models, it is possible to add an absorbent tube to extract the floating pollutants on the surface.

Protection of Doors and Underground Entrances

Water-Gate flood barriers are available in different sizes that allow them to adapt to different situations. It is possible to install them in the desired location: in front of a door, window, garage, elevator door, parking lot, underground entrance, etc.

Containment of Pollutants

By its nature, the Water-Gate barrier has the particularity of literally blocking a flow of water by creating a barrier. The water is housed at the bottom of the barrier and it deploys and fills automatically as the water level increases. Therefore, it is the weight of the water that nails the barrier to the ground and stabilizes it.

In the event of a toxic spill, the pollutants are contained inside the barrier and can be easily removed using different methods and accessories:

  • Extraction pump: water and pollutants are extracted from the contaminated area to an empty container until complete decontamination of the infected area. This practice is ideal in situations where the contaminated site contains non-floating pollutants.
  • Absorbent material: very effective intervention equipment exists on the market in order to facilitate the extraction of dangerous materials included in water, this is the case of certain booms and certain surface skimmers, absorbent powder or tubes, coals, active ingredients for organic solvents and others, which, combined with the Water-Gate WT model, demonstrate doubly superior effectiveness. Since the barrier traps pollutants in common, it only remains to install this equipment precisely upstream of the barrier to efficiently extract the pollutants.

Temporary Cofferdams

The WA models were designed for the creation of instant cofferdams. Ideal for rapid excavation work—repairing bridges, changing or repairing culverts, burial work in aquatic environments, pipeline crossings, riverbank restoration, pouring cement, dredging, lock maintenance and much more.

Deviation of the Water Ttrajectory

The water barrier can be used to divert the path of water to a specific area. This characteristic is ideal for carrying out aquatic works without interrupting the circulation of water. It allows the partial drainage of an arm of a river or a section of a watercourse.
