Description

Flood protection like never before

Part of the WL-Series, the Water‑Gate flood protection dam is specifically designed to provide full protection against flooding issues faced by cities and municipalities across the world. This unique and innovative flood response equipment combines simplicity, robustness, and effectiveness.

Safe and rapid intervention

The Water-Gate flood protection system is a turnkey solution, ready for use right out of the box. No water filling, air inflation or anchoring is required.

It is known for its simplicity and ability to be deployed quickly. To use it, just unroll the barrier, unfold the front part and let the water accumulates. The water pressure will cause the barrier to deploy and secure itself in place.

Say goodbye to sandbags!

Water-Gate flood protection dams are considered by many to be the perfect alternative to sandbags – as a single dam enables to replace thousands of sandbags. In addition, the Water‑Gate flood dam adapts to every situation and remains stable regardless of its extended length, direction of water flow, or slope of the ground. Water‑Gate flood protection dams are built to the highest quality and may even be installed while the flood is already in progress.

How it works:

The Water‑Gate flood protection dam comes as a PVC roll. The design uses the weight of the incoming floodwater to deploy and stabilize itself. Water enters and accumulates at the bottom of the barrier as the water level rises, causing the barrier to unfold and swell. The lightweight design allows for timely intervention in remote or hard‑to‑access environments.

WL-Series models have retention heights ranging from 6″ to 60″ (15 cm to 152 cm).

Flood control is now faster and easier than ever!

Flexible flood protection system:

The barrier is flexible enough to create inner or external corners and most type of configurations. In addition, once deployed, the barrier will not lock you in and the set-up barriers will not prevent crossing over. Walkers and motorists can move freely in both directions, whether it is before, during or after the barrier is deployed.

Proven by authorities:

The water-Gate barrier has been proven by the Ministry of Transports, Mobilité durable et Électrification des transports.

Ref.: #GUQ-02055.

Deployment crate:

Barriers can be supplied pre-joined in crates for fast deployment. The use of crates is highly recommended in emergency situations since they enable maximum efficiency in time and manpower. The crates also provide a solution to the storage of the barriers.

 

Advantages

Deploys in three easy steps

When a flash flood occurs, response time is critical. The Water‑Gate™ flood dam can be quickly and easily deployed in three easy steps. Step 1: Unroll the barrier. Step 2: Unfold the first fold. Step 3: Allow the water to accumulate inside...

Integrated ballast

The WL barrier has a weighted ballast bag that is sewn directly onto the front bib. This ballast bag creates a uniform weight across the length of the dam and molds to the shape of the terrain to limit seepage. It also helps prevent wind squalls...

Performance and certification

Water‑Gate™ flood dams provide retention up to 60″ (1.5 m) in height. Multiple barriers may be joined together in order to expand the area of flood control. Additionally, all models with a height exceeding 39″ (1 m) are FM approved. This...

4 golden rules for a perfect installation

1- Never dig behing the barrier | 2- Use a pump to move excess water upstream of the barrier
3- Place weights in front of the barrier to reduce infiltration | 4- Make sure you do not forget any object below the barrier

Main features

 

Main features of the WL‑Series

A. Ultra‑strong PVC‑coated polyester fabric resists abrasion for installation on any surface.

B. Stretched partitions for better adhesion to smooth surfaces.

C. Polypropylene handles to help raise the extremities of the barrier in special situations.

D. Small, galvanized steel plates in a polyester net sewn directly onto the Water‑Gate flood dam for ballast weight.

E. Heavy‑duty polypropylene handles for easy handling.

F. Float

 

Water holding back water

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-rising water dam

  1. Water infiltrates and collects inside the barrier.
  2. The water pressure helps the barrier unfold completely.
  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.

Determine the flood dam you need

1

ASSESS RISK

Determine the nature of the flood
Take note of the flood level of your locality

2

DEFINE THE TRACE

Define the potential protection perimeter
Identify the presence of obstacles (trees, walls, etc.)

3

CALCULATE HEIGHT

Identify the lowest point of the protection path

4

DETERMINE LENGTH

Allow extra length when resting on a wall
Take into account the footprint of the soil

5

SELECT MATERIAL

Complete the response plan with pumps, quick deployment box, additional ballast, special anchorage, etc.

Barriers coding explanation / Definition of terms

WL letters represent the product range, e.g.: WL for flood protection, WA for water supply/temporary cofferdam, WT for hazmat/oil spill containment.

The first two numbers (26) represent the height in inches.

The last two numbers (30) represent the length in feet.

So WL-2630 means: a WL Series barrier with 26 in height and 30 ft length.
