Quick Dam Water Activated Flood Barrier 17 feet, 1-Pack

This product is very effective as a barrier for unwanted water seeping into things you'd rather not. The construction next door has taken over two years and the concern was the change in elevation and contours, along with heavy summer rains. This is the second time we have purchased and is the third summer....so I'd say the product lasted two years with a year round all season installation between houses. It is easy to lay out. And we secured it with sawn logs to avoid it being washed out of the desired contour. It gets very swollen when rains are heavy and very much did the job required. I highly recommend.

O produto é bem ruinzinho, não serviu de nada aqui e paguei bem caro.

This solved my rain leaking back door problem by absorbing the rain and creating a barrier. Very good purchase

These were very easy to use. They start out very light and folded up. You just unroll them in the spot you want and after 3-5 minutes, they puff up and immediately redirects the water. You can move them around after they puff up too. They definitely saved my house from pools of water around the edges. Only negative is that some of the little beads(?) leaked out of some of the barriers. Not sure if they're toxic or not. Also, I'm not sure if they will shrink back to their original flat size. It's been about 4 days and they're still bloated. I'm going to move them to a sunnier part of the yard to see if they will shrink faster.

Good to have in yard
