I bought these just in time for the Brisbane floods (coincidence). They were instrumental in diverting water away from a dwelling on my property.

Use to soak up leaks in garage, but find that the drying out of the bags to reuse again or to store away for future use, does take some time when bags are full.
Is not a true sandbag. It requires the addition of water to achieve weight. Did not suit my requirements as I required weight of 25 KG. Bag stated weight when activated with water was 18KG so didn't use
After 24 hours, one of the bags opened all its contents spilled out.
Pathetic don’t waste your time.Once it drys out it blows away thought it filled with water but it submerges in water and becomes 18kgs until it drys out. Stupid idea don’t waste your time
Bought in prep for winter so haven’t used as yetLooking at instructions seems perfect for my needsWill update when appropriate
Brilliant, have saved us a fortune in helping to hold back water, highly recommend
Purchased to prevent overflowing rain water from flooding a courtyard. The bags fill as water comes into contact with them. Have not had a massive storm yet but 15 ml of heavy rain half filled the bags in the lowest point of the courtyard. So far so good.
