Emergency containment of polluted liquids | Water-Gate©

Create a containment dam in record time: retention of fire extinguishing water.

Deviate to a neutral zone: chemical pollution, contaminated liquids.

A light and flexible solution that fits all types of sites with no anchorage, whatever the surface (concrete, tarmac, earth, rubble, etc.) and relief (slopes, edges, obstacles, etc.).

Hydrodynamic ballast: the dam does not slip when faced with a sudden influx of water.

The Water-Gate© retention dam can be installed when the spill is already underway!

3 retention methods with Water-Gate© flexible dams

Water-Gate© flexible dams can be used in different ways adapted to the nature of the building in question (watertightness of walls, type of openings, underground areas to be protected), using the topography of the site (different levels, basins, natural slopes) and integrating the existing network structure (rainwater and wastewater).

Alongside openings

Fitted between 2 walls or supported by a facade

  • No works necessary.

  • Works even without electricity.

  • Can be crossed by emergency services in both directions up to mid-axle height.

  • Total retention volume = Building surface x retention height.

Next to buildings

Retention around the building perimeter (360° or in sections)

  • Allows for retention even if the walls are not watertight.

  • Total retention volume = Retention surface x retention height.

Diverted retention using gravity flow

Emergency retention dam in diverted area

  • Take advantage of the topography of the terrain.

  • Avoid flooding the whole building by using existing networks./p>

  • Prerequisites: gate valve or pneumatic dam.

  • Facilitates emergency rescue efforts.
