Meet FlowStop

How does it work?

The FlowStop flood barrier consists of two main parts: an upper cushion and a lower cushion.

The upper cushion is designed to push sideways against the wall. The intense pressure locks the device in place, creating a roof for the lower cushion.

With the upper cushion 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 water-resistant seal.

Why is it better?

Custom-made

FlowStop is custom-made to fit your opening perfectly, ensuring not a single drop gets through.

Easy to store

Similar to a paddle board, FlowStop can be rolled up and stored when deflated.

Easy to install

A double-action pump is included in your order. In only a few minutes inflate your FlowStop and keep the water out.

Super light

It’s easy to lift & carry and put in place.

High flood barrier

Order a tall flood barrier for higher water levels. FlowStops are Custom-made and can be as tall as you need. .

Is it strong enough?

FlowStops are made of PVC, making them resistant to debris, temperature changes, wind, and strong impacts. FlowStop is built using drop-stitch technology, which is commonly used in inflatable paddleboards.

This allows us to apply over 15 PSI of pressure inside the cushions, creating an impressively strong barrier.

This pressure fills in imperfections on the surfaces it contacts, forming 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 up to 75".

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.

If your FlowStop is:

Less than 60" wide: the minimum height is 31.5”.
More than 60" wide: the minimum height is 39.5”.

Depending on the surface of the opening and the height and width of your FlowStop, additional straps may be required. The straps are anchored to the ground with permanent bolts. See tutorial for more information.
