Aqua-Sac® is a revolutionary alternative to traditional sandbags for flood defence and emergency flood protection. Made from a heavy-duty jute sack and a non-biodegradable, non-woven inner bag with our patented centre stitch, the Aqua-Sac contains a Super-Absorbent Polymer. Simply submerge in water — in just five minutes, it absorbs up to 13 litres, creating an instant, self-inflating “sandbag”.
