HOW THE WATER-GATE WORKS
Water accumulates inside the barrier and exerts pressure on the bottom of the fabric, which keeps the
barrier in place. The speed or direction of the incoming water is not important, as it is the water pressure
that causes the barrier to open up.
WATER HOLDING BACK WATER
The Water-Gate barrier has a ratio of 4:1 meaning the surface of the barrier on the ground is 4 times
greater than its water retention height. It has 4 times more vertical thrust (toward the ground) than horizontal
thrust, allowing for good adherence. Typically, in order for water to be able to hold back water on most
surfaces such as asphalt or grass, a ratio of 1 to 2½
is sufcient to ensure safety. With a ratio of 4:1 the
Water-Gate barrier is very safe and the chances of it
slipping are very slim. The wider the barrier is the less
likely it is to slip. The Water-Gate water barrier is 33%
safer than required.
For areas where space is a concern, we also offer a 3:1
ratio, still higher than the recommended 2.5:1
