Meet Flowstop
How does it work?
The FlowStop flood barrier comprises two main parts: An upper cushion and a lower one.
The top cushion is designed to push sideways against the wall. The intense pressure locks the device, creating a roof for the lower cushion.
With the upper cushion inflated, the lower cushion is stuck between the ground and the upper cushion. As you inflate it, it will expand and press down against the ground, creating a water resistant seal.

Is it strong enough, though?
Flowstops are made of PVC, which makes it resistant to debris, temperature, wind, and strong impact.
Flowstop is built with drop-stitch technology, which is commonly used in inflatable paddle boards. This allows us to apply over 15 PSI pressure inside the cushions, creating an impressively strong barrier.
This pressure fills the imperfections on the surfaces it touches, creating a water-resistant seal.
Sizes
As long or as tall as you need.
Width
We custom-make FlowStop to fit the width of your opening. Please measure your openings from wall to wall
Height
FlowStop can be ordered to a height appropriate for your water levels. Investigate and plan accordingly by understanding your flooding zone needs.
If your FlowStop is:
- Less than 78"wide:
The minimum height is 31.5”
- More than 78" wide:
The minimum height is 39.5”
Depth
The depth of the flowstop depends on its length.
- Under 78" wide:
The opening needs to be at least 2.6" deep.
- Above 78" wide:
The opening needs to be at least 5.3" deep.
Make sure your opening is deep enough for your FlowStop.
Straps on Long Flowstops
Depending on the surface of the opening and the height & width of your FlowStop, it might require additional straps. The straps are anchored on the ground with permanent bolts. See tutorial for more info
Wall Surfaces
Flowstop works on most surfaces.
The gasket can fill up and seal up to 0.30 inches of gaps or imperfections on your wall.
Do not use it on surfaces that are too slick.
Do not use it against drywall.
