The UltraTech 5437 Flood Stopper Tube is a water-activated flood control barrier designed as a sandless alternative to traditional sandbags. Constructed from durable polypropylene fabric and filled with super-absorbent polymer, the tube expands within minutes when immersed in fresh water to create an effective barrier against flooding, leaks, and liquid intrusion. Its extended 10-foot length is suited for sealing entryways, garage doors, storefronts, and other longer openings requiring continuous protection.
- Water-Activated Flood Barrier – Absorbs fresh water and expands in approximately 2.5 to 5 minutes to form a stable flood and leak containment barrier
- 10-Foot Continuous Protection – Extended tube design provides coverage for long doorways, garage openings, storefront entrances, and similar access points
- Sandless Construction – Eliminates the need for heavy sand-filled bags while remaining lightweight and easy to transport prior to activation
- Engineered Polymer Distribution – Designed to maintain a consistent shape throughout the tube for more uniform barrier performance after activation
- Non-Toxic and Disposable – Manufactured using non-toxic materials and may be disposed of in accordance with local landfill regulations after use
