Guppy™ MAX Large-Scale Water Filled Flood Barrier is an advanced flood protection solution designed and engineered to provide MAXimum defense against flooding. The innovative 3-chamber structural and industrial design creates a solid trapezoidal shape when filled, allowing for MAXimum stability and flood mitigation.

Each Guppy™ MAX flood tube is 40” in diameter and 30ft long, providing flexible large-scale flood protection for any location.

Designed for heavy duty protection, this robust solution can be filled using a 2 1/2" fire hose, ensuring immediate readiness in flood emergencies.

Featuring a unique seaming flap, multiple units can be seamlessly connected to extend your flood barrier's length, providing comprehensive coverage tailored to your needs. Ideal for blocking and diverting water around perimeters, entryways, and crucial infrastructure.

The Guppy™ MAX water filled tube is reusable. Once a flood event is over, it can be drained carefully and put back in storage once completely dry for future use.

Deploy • Installation • Storage

Guppy MAX water filled tubes are rolled out in the desired location and filled with water utilizing a 2 1/2" fire hose.

We recommend being in close proximity to the water supply to fill as each unit holds 2,115 gallons of water.

Once the unit is filled, you will not be able to move the unit due to it’s weight, so please make sure the unit is in the proper location before filling.

Once the flood event is over, be sure to drain the tube carefully as to not flood an already saturated area with the water.

Before folding the unit back up, ensure that it is dry and free of water or debris. Store in a cool, dry place for future use.

Connecting Multiple Units

Each Guppy MAX tube has an extended seaming flap on one side of the unit. If you are deploying more than one unit, make sure that you have the correct ends abutting each other so you are able to connect the units properly when staging the product around your structure.

Use the integrated PVC ropes or tie-strings through the grommet holes to connect each unit securely together or fasten to the ground below using stakes.

Adding 90 Degree Corner Turns

Guppy Max is designed to be used in a straight run, or you can affix the Guppy MAX Corner Unit against each tube end to create a 90-degree turn.

The extended seaming flap on each side of the Corner Unit allows you to seamlessly connect adjacent MAX tube sections using integrated rope ties that are fastened and attached through the grommet holes on the seam strips of each Corner, to effectively and securely create an extended integrated perimeter section for full protection flexibility.
