The Guppy™ Water-Filled Flood Tube is a temporary flood barrier that helps redirect water and prevent flood damage at homes, offices, factories, events, and municipal buildings. It fills with a standard garden hose, and once full, the weight of the water turns each tube into a heavy, stable berm that holds back rising floodwater.
Guppy comes in 6", 12", and 24" diameters and in 10', 25', 50', and 100' lengths, so you can choose the size that fits your space and protection needs. A seaming strip connects tubes end to end to create a longer, continuous barrier. For tents and events, Guppy is also available in white. For larger-scale protection, Guppy MAX tubes measure 40" in diameter and 30' long.
Guppy helps hold back water during heavy rain, severe storms, river flooding, and flash floods. When the water recedes, the tubes drain, roll up compactly, and store until the next flood threat, ready to be reused again and again.
Guppy is a practical addition to emergency plans for buildings, facilities, and municipalities.
