FAQ

Our inflatable flood barrier devices are custom-made to fit your door, window, garage frame, or any other opening. When inflated, a FlowStop creates a high-pressure, sealed barrier within the framed opening, effectively preventing water from entering.

Yes, our technology is engineered to withstand strong forces from both pulling and pushing, including high winds.

Yes! FlowStop is specifically designed and tested for reuse and easy repair.

Yes, FlowStop was specifically designed and tested to withstand various types of debris encountered in different conditions—including logs, sharp objects, and more. It has also undergone rigorous testing under extreme pressure scenarios. While constructed from durable PVC and engineered to absorb strong impacts, FlowStop is not intended to function as a hurricane shutter.

Yes, FlowStop is an inflatable device designed to adapt to imperfections in uneven frames—whether it's a window, door, or garage opening. In some extreme cases, we may recommend leveling the floor, filling in large cracks, or applying Flood Protection Paste to ensure a secure seal.

Yes, FlowStop can adapt to and maintain a strong seal, even on sloped surfaces.

FlowStop weighs approximately 0.007lb/sq. For example, a FlowStop measuring 36 inches wide by 31.5 inches high weighs about 6.8 pounds.

A FlowStop flood barrier can be set up in minutes, but protecting an entire home may take several hours. We recommend preparing and setting up most of your FlowStop as soon as you receive the first flood warning.

Even in extremely high temperatures, FlowStop maintains its shape and strength without alteration. It has been tested to withstand temperatures as high as 167 degrees Fahrenheit.

FlowStop is easy to roll up and can be stored in a box or hung by its handle.

Yes! We recommend testing your FlowStop as soon as you receive it. This way, if any issues arise, we can address them before an emergency occurs.

In extreme cases involving intense, sideways driving rain, some water could potentially find a way in between the barrier and your door. If this happens, the amount of water that gets trapped in this space is usually marginal. However, it is a very small volume compared to what a storm surge would bring, and there are several highly effective ways to minimize and manage it so your property remains fully protected. Every home is different, which is why our flood experts are available to walk you through the best techniques for your specific setup and offer custom-tailored solutions to give you that extra layer of protection and prevent water from getting through.

In an extreme case, a FlowStop inflated to 15 PSI at 77°F (25°C) that then reaches 131°F (55°C) in direct sun, will see its pressure rises to about 18 PSI. That's a real increase, but nowhere near a failure point.
