Follow the instructions in the next eight essential steps to determine your needs.

Note that sandbags positioned in certain places will also help limit infiltration.

How to determine the necessary length?

The calculation of the necessary barriers is always done from the red line as illustrated in the previous image.

Determine the required retention height
  • The height may vary depending on events history, the slope and other factors.
  • Take into consideration the lowest point of your land to calculate the necessary height.
  • See the opposite chart for the distance required to install the barrier (red line).
  • Pay special attention to obstacles: increase the length as necessary to avoid any obstacle, or create corners to go around them.
  • The end joints (Velcro joints) should be at least 5 feet from the corners.

Our advices

General advice
  • Be sure to select the correct barrier size and be equipped with pumps and other necessary tools to prevent infiltration and manage rainwater.
  • All barrier models are compatible, with the exception of barriers with a height of 6 ″, which can only be attached to barriers of the same model.
  • Each Water-Gate barrier has a depth ratio of 4 to 1, which guarantees excellent stability.
Security
  • Avoid placing Velcro seals around the corners.
  • Pay special attention to obstacles when measuring the space you need to install the barrier.
  • Sandbags are necessary in certain places of the mud flap before the barrier to minimize infiltration.

The 4 Golden Rules

To successfully install your Water-Gate barrier!

Never attempt to contain a leak behind the barrier

If there are leaks, prevent water from entering the front of the barrier. In most cases, this problem is caused by infiltration upstream. If you try to control a leak behind the barrier, it could create a small pool below it and make it unstable.

Pump the water behind the barrier

It is important to leave enough space between the building and the back of the barrier to accommodate a water pump. Water that infiltrates under the barrier should not be allowed to accumulate behind it.

Place a regular weight on the front flap

Do not attach the barrier to the ground. The water that enters the barrier creates a weight that holds the flowing water. It is important to place weights on the front to reduce infiltration. The WL model, created for flood control, is designed with integrated ballast allowing rapid deployment. The weights reduce infiltration under the barrier and allow it to stay firmly in place on the ground.

Prevent water from accumulating under the barrier

Remove all objects that could cause infiltration under the front of the barrier. It is designed to stay in place on all surfaces, be it asphalt, gravel, grass or concrete. However, if there is too much water under the front, the barrier will not adhere as well and could slip. Therefore, it is important to make sure that the soil is free of all objects that could cause water to accumulate under the barrier.
