Quick DamQD1224-6 Water Activated Flood Bags 1ft x 2ft, 6-Pack, Black

Used this to stop water from flooding into our living room. We share a drain with a neighbour and it lies on their side of the private balcony of our flat but it seems to be blocked up so during heavy rainfall the water baIcks up and fills up the balconies like a bath and eventually breaches the door to the balcony. This has been the only thing that has helped us not to get flooded again. Easily stackable. The gel swells up inside and stays like that even when dry. Not sure how long they last but they have been in place for 4 months and we haven't had any water come through them.

Instead of trying to store big bulky sandbags I bought these instead. So easy to store and when I unfortunately needed them they were easy to use and they worked.Downside: had to weigh them down as I put them out dry rather then 'wet' them before, but that was my choice. They also take a very long time to dry out again (but they saved my house so I can deal with the drying time!)

I wish I could give 100 stars. It is great product. If you have any flooding risk , get them. It will protect you .

The media could not be loaded. Best things ever! Saved my bungalow from flooding. I had seconds to react and they inflated immediately.Buying a second set to keep as a spare as I know they take time to deflate.

The product was better than expected - put my mind at rest that my leaky roof would not be a problem while I was away from home as the bags were in place soaking up any water coming in

Arrived 6 days before due date. Pack of 6 Quick Dam Sandless Sand Bags 600 mm Self Inflating No Sand Required!. Second pack that I have bought. Hope that I don't have to use them. But the way the weather is its better to be safe than sorry. Will update if I use them.

These bags are quite effective in stopping water ingress.They come as little more than a long bag of crystals, very light in weight.These crystals absorb water when in contact, and thus become a barrier.Problem is, that after the water recedes they are very heavy to move, and take an age to lose the the absorbed water.If anyone knows of a quick way to reduce their water content, please let me know.

The only reason I haven't given 5 stars is that I haven't used the bags yet. However, I have them ready in case I'm about to be flooded again so I already feel better prepared & less stressed.
