Pumping of seepage water

No mobile flood protection system is completely waterproof. The very surface on which the dam is laid is not 100% watertight.

It is imperative to combine the Water-Gate © flexible dams with pumping means.
As on a boat the principle is to collect the trailing water, at the low point downstream of the flexible dam and to reject them over the ridge.

The leakage rate depends on many factors:

  • Underground pipes
  • Type of soil
  • Obstacles on the ground
  • Retention height (hydrostatic pressure)
  • Quality of implementation
  • Pluviometry

We calculate a leakage rate with safety margin for each installation.
We recommend the use of self-priming pumps or low level residue pumps coupled with generators.



Perfectly adapted to the complementary ballasting of the Water-Gate © barriers: 15 KG / linear meter. Robust and easy to handle (three handles), they are easy to load and unload in water: polyethylene mesh.

SERIE WL-06: a pocket barrier for emergency deviations. Efficient and incredibly simple! WEGDE-Bag ©: a sealing wedge to be placed in line with the openings to limit leaks.

We pair our Water-Gate protection devices with the best aluminium solutions: narrow openings, support points for flexible barriers.

If the risk to underground networks is not dealt with, surface protection will be inadequate. MegaSecur.Europe studies the networks of the site to be protected and provides a solution tailored to each situation.

No mobile flood protection system is totally watertight. We provide pumping solutions to collect water that has seeped through and discharge it beyond the dam: self-priming motor pumps or submersible pumps coupled with generators.
