In the video, villagers spread waterproof sheeting over a sandbag-reinforced earthen barrier near floodwaters. They place sandbags atop the sheeting edges to secure it against currents. This prevents flood seepage into the barrier structure, reducing collapse risk by over 80%. The sheeting also disperses water pressure, protecting the sandbags from erosion. Such rapid, low-cost methods help communities buy critical time during emergencies. Collective action like this builds essential flood resilience in high-risk areas.
