Our company

Who we are?

First developed in 1998, in Victoriaville, Canada, MegaSecur Inc. is the main manufacturer and distributor of Water-Gate barriers: the fastest and most flexible emergency response equipment for water-based incidents on the market. Our head office is located in Victoriaville, Quebec, Canada.

The Water-Gate barrier is designed for a wide‑ranging clientele, including clients in the industrial, commercial, medical, municipal, government, airport, military, and recreational industries. It is also quick and easy to deploy, cost-effective, and can be reused hundreds of times. Nothing else compares!


Global success

Water-Gate barriers are used in over 37 countries in the world, including Canada, United-State, France, Mexico, Peru, Chile, Belgium, China, United Kingdom, Australia, New Zealand, Japan, Panama and other.

Our distribution network gives us proximity to our clients, which offers a customer service that will fit their needs.


Much more than a flood protection solution

The Water-Gate barrier is a turnkey solution, which is designed to provide a rapid, reliable and safe solution in an emergency situation. It is lightweight, eco-friendly and can easily be transported.

So, it is not surprising that many countries around the world use the Water-Gate barriers to control flooding, work in submerged areas, put in water‑intake structures to fight fires, contain pollutants released by toxic spills or drain branches of rivers.  On average, the time required to install a medium-sized barrier is less than five minutes.



Water-Gate systems are high-end equipment, manufactured by dedicated and passionate employees. All our products are made from industrial designs, thus guaranteeing their uniformity.

After the manufacturing step, each barrier is individually and strictly inspected before shipment. Your security is our number one priority. We are proud to say we’ve been helping keep people and communities safe both near and far for twenty years now!

How it works

Water-Gate water barriers are made of polymer canvas and designed so that water collects inside the pockets. The barriers automatically open as they fill with water.

The concept is simple: The weight of the water keeps the barrier in place, just as air pressure holds a parachute open.



The Water‑Gate flood dam has four times more ground surface than the water being retained, thus four times more vertical thrust (across the ground) than the horizontal thrust for proper adhesion. For the water to hold back the water on most surfaces such as asphalt or grass, a 2½‑to‑1 ratio is usually sufficient for safe installation. The Water‑Gate flood dam’s 4‑to‑1 ratio is therefore much safer and the risk of slippage is unlikely. The wider the barrier, the lower the risk of slippage. The Water‑Gate™ flood dam is 33% safer than required.

Modular and self-locking water dams

Steps to follow

  1. Water infiltrates and collects inside the barrier.
  2. The water pressure helps the barrier unfold competely.
  3. The integrated floater allows the top part of the dam to float and absorb the motion of incoming waves.
  4. The accumulated water pressure stabilizes the barrier and keeps it in place regardless of the terrain beneath.

No need to pump water inside.

The inventor

The Water-Gate water barrier was invented by Daniel Dery on January 1, 1998. An industrial designer by training, Daniel is a visionary who is passionate about innovation and industrial design.

The idea came to him on New Year’s Eve. He was sitting in his living room, eyes glued to the television, watching a rundown of the top stories of 1997. One of the year’s biggest headlines was Manitoba’s Red River flood (one of the worst natural disasters in Canadian history). As he watched hundreds of soldiers and civilians filling and stacking an astronomical number of sandbags to block the threatening waters, a light bulb went off. There had to be a better way.

He thought of fastening long plastic tubes together and attaching them to a giant float. The water would flow into the tubes, fill them, and create a flood barrier out of water instead of sand. This would eliminate the need for thousands of sandbags in addition to freeing up valuable time, energy, and resources.


The beginning

Driven by determination and the desire to create a product with the potential to help thousands of people, Daniel made his first prototype that very day. With the vision of his project growing ever clearer, he put together a makeshift model in his kitchen sink. The tests were conclusive enough for him to carry on his work. Given the magnitude of the project, he decided to devote himself entirely to this new challenge, his ultimate goal being to develop water barriers that would be distributed worldwide to combat one of Earth’s most destructive natural disasters—floods.

Needing a name for his invention, Daniel went the simple route and dubbed his work the Water‑Gate water barrier.

Daniel Dery - the beginning of the watergate flood protection dam


The beginning


  • For the first eight years after the founding of MegaSecur, the manufacturing of Water-Gate is outsourced to Mégatex.
  • The first river test is a success as far as the notion of water stopping water, but a failure as far as design. Since the tubes are stacked on top of one another, they start sliding around as soon as the barrier approaches full capacity.
  • Daniel Dery megasecur water-gate flooding protection barrier


  • After a lengthy process of trial and error and major improvements in design, the Water Gate water barrier is fully operational. An official version sees the light of day in September 1998 and is immediately launched on the market.
