How does it work?
The FlowStop flood barrier is made of two main parts: an upper cushion and a lower chamber.
The upper cushion is designed to push sideways against the wall. The intense pressure keeps the device in place, creating a roof over the lower chamber.
When the upper chamber is inflated, the lower cushion is trapped between the ground and the upper cushion. As it inflates, it expands and presses down against the ground, forming a watertight seal.
FlowStops are constructed from PVC, making them durable against debris, temperature fluctuations, wind, and impacts.
They are manufactured using drop-stitch technology, similar to that used in inflatable paddleboards.
This enables us to inflate them with over 15 PSI, producing a robust barrier. The pressure also helps to contour around surface imperfections, creating an effective water-resistant seal.
FlowStop sizes
As long or as tall as you need.
Width:
We custom-make FlowStop to fit the width of your opening up to approximately 177".
Please measure your openings from wall to wall.
Depth:
The depth of the FlowStop depends on its width.
-
For openings under 78" wide, the opening needs to be at least 6" deep.
-
For openings wider than 78": the opening needs to be at least 8" deep.
Make sure your opening is deep enough for your FlowStop.
Height:
FlowStop can be ordered to a height appropriate for your water levels.
Investigate and plan accordingly by understanding your flood zone requirements.

Beyond that, we cannot guarantee that it will remain watertight and resistant.
-
It is essential to inform the user that the pressure must be checked every 2 weeks.

How to install straps on my FlowStop
For devices wider than two (2) meters (+78 inch), straps and their carabiners are also provided.
The installation of the straps and the securing of the anchors to the ground are the sole responsibility of the customer. The fixing elements (concrete anchor bolts, concrete plugs and screws suitable for a minimum load of 300 kg (+661 lbs), screws or any other equivalent accessory) are not supplied by FlowStop.
Compatible surfaces
Brick
Stone
Concrete
Plaster
If your surface is too smooth, such as aluminum or painted wood, your FlowStop will slide upward instead of pressing downward.
In this case, it will be necessary to place a non-slip strip on each side, which we will provide with your order.
Incompatible surfaces
FlowStop barriers cannot be installed on wooden cladding, nor on aluminum or PVC cladding that is too flexible, nor on plasterboard cladding. Indeed, the pressure exerted by the FlowStop barrier would be too great and could cause damage as well as improper installation of the device.
Solutions to add more depth
Permanent and temporary Brackets/posts can be installed to add the needed depth.
Brackets and posts must be sealed to the wall.
Our patented technology
Double Cushion
The first cushion is designed for lateral plating in the opening to be protected, while the second cushion is designed for plating towards the ground.
EPDM Gasket
All-round EPDM gasket for excellent sealing, with corners that fit perfectly around the corners of openings.
Drop-Stich Material
FlowStop is made from Drop-Stitch material (flat, rigid surface when inflated, but rolls and transports when deflated).
