Introduction

​The Flowstop flood barrier is composed of 2 cushions. ​

The top cushion is designed to push sideways against the wall. It will lock the device in place and act like a roof when pressured.

The lower cushion is now stuck between the ground and the upper cushion.

When you inflate it, it will expand and press against the ground, creating a perfect waterproof seal.

To use Flowstop, you need a framed opening.

In the absence of a frame, contact us, so we can help you build one.

02

Width the frame

​Your flowstop can be as long as you need. 

Measure the width of your opening from wall to wall.

Please, make sure to measure the size of the opening you want to protect and not the size of your door.
