Worried about heavy rain or flooding getting into your garage, basement door, or driveway? These Windyun barriers are a modern, reusable alternative to heavy sandbags. You get 8 flexible tubes, each 10 feet long. They come dry and flat. When a storm is coming, you just soak them in water (they need about 8.5 gallons each to fully activate). In about 5 minutes, they expand to become a dam about 3-4 inches high and weigh around 68 lbs each, creating a solid water barrier. They stay active for months if left wet, then you can let them air-dry and store them flat for next time. No sand to haul, no heavy lifting when dry. Just lay them across door thresholds, walkways, or gutter runoff areas to divert or block water. A smart, low-effort solution to protect your home from water damage.
