We gave up on sandbags after our experience with hurricane Irma...Sandbags do not stop rising water no matter how many are stacked. However these Quick Dam Flood Barriers have worked wonderfully and we have used them through all the subsequent heavy rainstorms coming our way. I have bought several and will barricade all the openings to my home during the upcoming hurricane season. Stack them if high water is expected. They are worth the money.

We used these during Harvey and they helped save the back of our house. The water was coming up over our patio door and seeping in through the floor due to bad drainage in our backyard. We deployed these once we realized and they stopped any further damage. They don't seem to dry out all that well (or maybe at all) because when you leave them out in the sun... you can forget and then it rains (oops). So sadly these are really just a one-and-done kind of usage. I'm concerned about throwing them out though? I'm not sure about the environmental impact they'll have if we just toss them in the trash.

I ordered this water barrier bc of the threat of Hurricane Florence this weekend. It arrived in 48 hours just in time for a huge storm (unrelated to Florence)! I put down one 5’ segment outside of my back door. The rain water was already rising. The barrier started absorbing right away! I’m delighted. An hour later the thing is huge! And keeping water from entering! I’m so excited it’s working! I’m intending to add the other one when the hurricane arrives. I’m already super pleased I didn’t have to fight everybody at Home Depot for something like this! Plus it arrived in time for me to try it out before the storm. Unless it fails me this weekend, it’s already a 5-Star purchase - and I’ve only had it out of the box for a couple of hours!

Purchased 2 of these to stop water from going into my apartment through 2 sets of sliding doors on my balcony. They worked like I could never have imagined. I've since had the drainage fixed so the problem is solved but I read the reviews and ordered these and I wasn't disappointed. I did my research because my challenge was a flooding patio balcony with slow drainage and the water would back up and enter my apartment under the sliding doors. This product worked through several severe storms over a few months that dropped inches of rain in short periods.

These work really well. Put them in place to prevent water flow over newly seeded lawn - they're flat until water hits them, then they swell to 4-6 inches inches high. The 5 foot length is enough for a typical stairway/doorway opening. After they dry out they turn flat again, but will swell back up the next time it rains, so it's important to anchor them down with a couple of rocks or bricks on each end so they don't blow away when they dry out.

I cannot give this product enough stars! I live in Darlington, SC where we just experienced Hurricane Florence. Thankfully, we dodged a direct hit, but we didn't dodge the RAIN! We enclosed our porch years ago into a sunken den and have never experienced rain like we had that day. My son-in-law had dug a trench and I already had some sandbags down. I put the flood barriers up to my door and just prayed. As you can see in the pics, there was water up to my ankles! I took a pic from the inside of my den as well and one after the water had receded. The Quick Dam Flood Barriers held and kept water from coming in and flooding my den! This was a quick Amazon search and purchase the week of the Hurricane..Amazon Prime got it here.. I HIGHLY recommend this product!!

I was pleasantly surprised with these as I didn't know quite what to expect. Basically, it's flat and when it gets wet it expands as it absorbs the water. It flattens again as it dries out. I put one strip on the floor just inside the end/corner of the overhead garage door as water always comes in when it rains. Apparently the floor is just slightly lower there to allow the water in, but this seems to absorb the water before it gets to anything. I'm very happy with it, it does what it's designed to do. That said, if you are looking for something to divert the water you'll need to go with a normal sandbag.

I love these barriers! I will order again if needed. My parents were getting water under the back door. This was an easy solution to the problem until I can get a proper fix. 1 barrier has been in place for roughly 2 months that had a few heavy downpours. NO water coming in! I will keep these on hand and recommend them to anyone with a water leak problem.

I have old fashioned (hand dug) dirt and rock cellar and have been getting water seeping into it from outside alongside of the house. The house is on a slight slope and when it rains heavily, water pools on sidewalk and eventually ends up in cellar. I got these in hope that it might help with the water seepage. I have several of these and placed next to house (until I can get sidewalk fixed) it does help. Would it stop a flooding river - nope but I believe it would help at doorways, garage doors, etc. When wet it puffs up and helps curb the water from going past it. For me and my situation it works, it comes in various sizes. I'm just going to leave them out until it gets cold and there is no chance of any rain. Wish I had found them sooner.
