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.

MegaSecur has developed a tailor-made spillway for lightweight discharge (DN 450). With no pump, it is environmentally friendly and features a flexible pipeline for downstream discharge. Several spillways can be positioned side-by-side if necessary.

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.

The Water-Gate© filtration dam combines the advantages of flexible cofferdams and natural straw. It allows the water to be decanted and filtered according to its turbidity.
