WATER HOLDING BACK WATER

The flood barrier has 4 times more floor surface than the water being retained, thus 4 times more vertical thrust (or on the ground) than the horizontal thrust allowing proper adhesion. For the water to hold back the water on most surfaces such as asphalt and grass, a 2½ to 1 ratio is usually sufficient for a safe installation, therefore, the Instant UnderFlow Dam s™ 4 to 1 ratio is much safer and the risk of slipping is unlikely. The wider the barrier, the harder it is to make it slip, we can then conclude that the Instant UnderFlow Dam™ is 33% safer than required.

Steps:
  1. It will unfold and fill as the water infiltrates inside the barrier.
  2. The water pressure will completely open the dam.
  3. The sewn in floater will allow the top part of the dam to float and follow the motion of the incoming waves.
  4. The accumulated water pressure stabilizes the dam in place no matter the terrain.

Note: It is not recommended to use the Instant UnderFlow Dam for installation on concrete.
