Empty woven polypropylene flood sandbags are an industry-standard, affordable, and high-performance solution for rapidly staging emergency water barriers. Supplied unfilled, this 10-pack configuration is exceptionally easy to store flat in a garage, cupboard, or vehicle boot until a flood warning or site ballast issue occurs. When filled roughly one-half to two-thirds full with granular material (such as sharp sand, gravel, or soil), they conform neatly to irregular ground surfaces to restrict, slow, or redirect high water flows away from residential doorways, garages, and low-lying pathways.
