## Description

Product Description               The HydroSack is the most important development in emergency flood protection since the invention of the sandbag. Before use the HydroSack can be safely stored in a dry location for 5+ years. In the event of a flood simply place the HydroSack in water - or spray with a hose. They will quickly expand and will absorb up to 20 litres of liquid, and thereafter will act as a barrier to stop excess waters surging into your home or premises - it will retain it's weight for over 3 months. Since the HydroSack only contains pulp and Super Absorbent Polymer, both are harmless to the environment, and after slitting the sack, they can be dispersed into the soil without any harmful effects. The HydroSack has built-in handles for easy movement, especially useful in emergency conditions. The unique 3 section structure of the HydroSack allows a controlled spread which prevents the contents from moving from side to side. A unique product of Gravitas International Ltd.                  Safety Warning               Warning: when using outdoors, pay attention to the risk of flooding. Dry completely before use and do not store near open flames.

## Questions & Answers

**Q: how long are they**
A: 145cm

**Q: Could they be used to put inside my garage door to stop wind and rain blowing underneath and stop the wind whistling. If so how many would I need.**
A: Each snake is approximately 3ft long and yes it will do the job you want as they are quite pliable , I don't know how wide a garage is im afraid but im sure you can work it out off this, the hydrosnake comes in a pack of 2 so you would have approximately 6ft coverage . They are an amazing product , they can soak up an unbelievable amount of water .

**Q: How long is the shelf life unused?**
A: Not really sure.  I ordered 2/3 sets and used one last winter and one in the summer.  I have kept the last set unopened and thankfully unused so far but can see no reason for it not to work if and when required.  It is an excellent product.

**Q: Major flood after the rain so bought these. do i have to soak them first or would the rain do the job? can i reuse them? if so how?**
A: They recommend wetting the “snakes” a bit before first use but we found the rainwater trying to get into our garage did that for us. They can be reused until they go hard. They get heavier as they absorb the water so we left ours in the sun to dry off a bit. The inside material  can be spread on earth in the garden which was one of the reasons we got them since easy to dispose of.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Reliable
*by A***R on 21 September 2023*

I use this to stop water entering my garage (it’s on a slope). I replaced old ones yesterday morning as they don’t last forever (4 months tops). Last night we had exceptionally heavy rain fall, the worst in years and the hydro snake did the job and kept the garage dry. I’m really happy and just ordered another pack. Sand bags are really hard work to fill and heavy to place and they also fall apart after a while so these are an excellent option (but not cheap).

### ⭐⭐⭐⭐ Did what I wanted
*by P***S on 29 January 2020*

These worked well inside my house. I have a leak which comes up through the ground in the kitchen when it rains hard. Luckily there is a slight slope to the corner so it only spreads to the rest of the room which the water keeps on coming. These 'sandbags' did the job preventing the water coming further by absorbing the water in the gell inside. I can get rid of some of this water by stamping on them outside. But on the whole once they have absorbed water it is difficult to store them. I am waiting to see whether the water will eventually evaporate. I bought several but so far have only needed to use two. I'm still working out the best way to use them.

### ⭐⭐⭐⭐⭐ Will be buying again
*by I***P on 9 July 2023*

I bought these in 2017 after experiencing a blocked drain overflowing and water flooding into the house. Unfortunately the drain became blocked again and water started entering the house, I'm so so glad I had these on hand. Quickly deployed and it absorbed so much of the water that was coming in. Made a huge difference. I shall be repurchasing to have on hand for any future incidents.
