Not perfect, but nothing else like it. Essential if you deal with basement flooding
SO here's the short review, I bought these 'just in case'. The reviews were mixed, but my basement was going to flood after the snow melted from a WI winter. You can read my experience below. Well it did flood, I caught it at the beginning. I placed these bags down where it was coming up and they absorbed the water and also acted as a barrier to make the steady flow drop down to a very slow trickle that I was able to keep mopped up by placing a towel down in front of the bags. This helped immensely while I got to the source of the flooding. I bought more for next time. Not quite sure if I'll be able to reuse, and I wouldn't necessarily use these again to clean the mess, but if you know where the water is coming in at and place it there, I would use it for that as it does slow down or act as a barrier preventing further mess. The long review with other products: I knew it was inevitable this Spring, my basement was going to flood. No way around it. I hired a lemon of an excavation company last year to stop it, they did the worst job imagineable and made the problem worse. They basically created a basin that collects rain water up against my house and then just DUMPS it into my basement. Plastic sheeting on the outside helps keep the rainwater out, but after a WI winter with heavy snow & ice, I was concerned that I didn't quite make sure I placed enough sheeting down. So, after a day of chunking ice & vacuuming water on the outside so I remove old sheeting and place new down new before March rain... I placed these sensors down. I was pretty confident only a small amount would leak in the usual spot. I thought 3 sensors was more than enough and I'd place the other 2 in areas of mild concern. Well the usual spot didn't leak, my efforts of ice picking and vacuuming (and probably worrying the neighbors) has paid off. The water came from under the house! A sensor went off just as the water was trickling in. I ran to action... placing towels and quick damn bags down to keep the water from flowing in from the area in the floor. I only had maybe 1/4-1/2" of standing water in a low spot of the basement floor. I discovered my sump pump had actually burned out! And my drain tile was overflowing! Now, keep track of all the gadgets I mention in this post if you deal with flooding, because I believe my paranoia saved me this year... I still had messe, but I cleaned them up quickly and my life was only derailed for a few hours vs days like usual. I love my basement when it's dry, I have a little gym down there. Its my version of a she-shed... Not only did I purchase the quick dam bags, I purchased a portable pump in case s#!% hit the fan and the flooding got bad... so when I discovered my sump pump quit working, I was able to drain the basin and draintile in about 20 mins once I set up the portable pump and garden hose. So make sure you have this essential in your power toolkit also! Because when I discovered the pump was out, it was 630 at night in a rural area where every hardware store was closed and the closest Menards is 45 mins away. I would've had to drive there while my house continued to flood. I just kept up with the portable until I could get my sump replaced! You know what they say, an ounce of prevention is worth a pound of cure! So then the 2nd time the sensors went off, it was because I realized after all this mess with my sump pump, I had unplugged my water softener. I plugged it back in, not realizing the thing drains and the drain pipe was not pointed back into my drain basin where the sump pump is. (K, folks, I'm a single mom with NO mechanical ability AT ALL, everything I have learned in this area is because I'm in desperation to fix an issue and I don't have a man to call) So after I plug it in, and I'm all thankful that everything is finally fixed and I probably survived Spring flood season already, I sit down with a cup of coffee so glad that all the above steps were in place and things didn't turn out as bad as they could've, a sensor goes off 😞🤬 66 gallons of water from that f'n water softener. Imagine if I didn't have the sensor tho, and I just sat upstairs enjoying life thinking all was peaceful and calm while it just kept pouring water in! I caught it 10 mins in thanks to these and was able to stop the flooding and clean up the mess in an hour. So here's your flooding grocery list: GOVEE Water sensors (these are great, especially if you're away from home like I am!) Quick Dam flood bags (can absorb, act as a barrier to keep water from continuing to flow in) Wet vacuum Portable sump pump Dehumidifier Flashlight that you keep on a hook near the area of flooding because you should cut power to the house until you know its safe to enter without getting electrocuted Lots of extra towels to dry up the floor after you've removed the bulk of the water! Husband 🤣🤣🤣 jk

Finally solved my flooding problem - wow!
I have a sloped back yard and an inset exterior stairwell that leads down to the lower level of my house. When we get a lot of rain, water gets in the house. I have spent all kinds of money building an enclosure around the stairwell, regrading the walkway, building a little dam - you name it. While all those things made *some* difference, I still have gotten a little water. I was at my wit's end. A friend saw these and mentioned them to me. I read the reviews and decided to give them a try. Two days after they arrived, we had a flash flood. No water in my house. None. I put my bare foot on top of the Quick Dam that was at the downstairs door, and it was dry. I thought no water had gotten in. A little later, I turned it over to doublecheck, and it was indeed wet. Then I checked the one in the bottom of the stairwell, and it was swollen but not overflowing. My point - these sandbags can take in a LOT of water. They had room for much more. I bought a bag of 6, and I don't know that I'll ever use more than 2 or 3. They dry out pretty quickly in between rain storms. But I have extras on hand if we get recurring deluges. I'm in awe. And I no longer have to panic when the weather forecast calls for 2 inches of rain. This product has made a huge difference. Update January 2015: Five months later, I can still attest to the effectiveness of these sandbags. (And as you probably noticed, I technically don't use them as sandbags - I use them as water absorption bags.) The one issue with them is that you need a warm sunny day to dry them out. You need to be able to put them somewhere where the water will evaporate efficiently. That's a problem in the winter when it's cold and there's less sun to help out. I have bought another box of these to help me with my water issue, and I'm not complaining. If that's all it takes, I'm fine with this minimal cost and effort. It's just something to be aware of.

Don't last as long as expected
These bags were immensely useful for the past 9 months as we've had so much rain in the Northeast. The rain pours down my steps to my house. These bags worked terrific as I lined them at the top of the stairs. I haven't moved them in 9 months as they've never dried out - as it keeps raining! However, they are totally useless at this point. They never dried out due to inclement weather, but they no longer have any activation material. They are now just a black bag that are wet. I was hoping to get a few years out of these...if I got two years out of them - I would give them a 5 star review!

Worked great and much lighter than sandbags!
These saved my patio from being flooded in a flash flood we recently had. Houses in my area are built right on in the ground, so there's no porch. I have a flat patio at the front door, and the patio roof drips a lot in the rain. The water literally made it up to my front door! But not inside--thanks to these flexible flood barriers. With no advance notice, I saw big puddles on my street that popped up quickly, after just a few minutes of rain. I ran to get these barriers, which had just arrived day before. I got drenched while putting them in place to absorb water running of the patio roof, and I continued laying them all the way to the front door. All the barriers got wet, absorbed water, and kept my living room floor intact! 100% recommend. You can stack them to create a wall if you have high flood level or just lay them out, slightly overlapped like I did, to absorb water and prevent water flowing into the house. Fire stations in flood zones should give these out, because regular sand bags are too heavy to use for smaller people. I am drying these out right now, (it took 2 days of sun) and they're supposed to be reusable. I'll update this to include how they work when reused. Darn, app won't let me upload photos!

Excellent product
Two of these stacked on top of a plastic film are good for doorways. Now that I know (Company answered the question) they have a shelf life of 10 years or more, I am comfortable keeping several of different sizes in a tote for storm season to come around. Experimenting now for the first time on reuse -- 3 weeks and they are still drying out. Not optimistic but don't really care -- will happily trash them and use new ones next round as before if necessary. At my age I cannot handle sandbags and this product is fantastic. Even one layer of those across my doorways or garage door would be impossible for me. Use: I put in place, hose down to partially expand (enough that wind wouldn't take away), and let the rising water expand them the rest of the way. Outstanding product. Cost is reasonable, storage for future emergency use takes little space and shelf life is long, lightweight for movement, easy to expand, and most importantly, they stop water intrusion.

Worth buying for peace of mind
Very absorbent and convenient way to add a layer of protection.

excellent way to find a leak or stop one
We used these to water test our house to find a leak. It worked great to create a controlled area so we could see where water was entering the house. Our son had used them effectively to stop flood water entering his cabin on a river. The value for the money was great as it has helped us fix a leak with smaller chance of error. It was Very easy to use. We used it outside to stop the leak from entering and to control where the water could enter.

Ok
These are better than nothing but don’t hold much water. I think they need more of the water absorbing pellets inside. When the have absorbed water they leak when picking up to throw away. I’ve had other brands that hold more tightly and don’t leak as much. I’d rather pay little more for efficiency. They aren’t heavy when not wet. They take up a lot of room because more fabric than absorbent particles. Won’t intentionally buy again.

un piccolo grande aiuto
è utilissimo, lo posiziono sul balcone davanti alla porta finestra, dalla quale regolarmente filtra acqua quando piove in modo abbondante, e non mi è più entrata acqua nel corridoio, consigliatissimo

Apoyo para inundaciones caseras
El año pasado 2025 éste producto me ayudo mucho. En la colonia sufrimos de inundaciones cada época de lluvias, y cuando nos toca trombas sufrimos mucho. Éstas bolsas cumplen al 100% su función, solo hay que ser pacientes y encontrar el mejor método a nuestra conveniencia, en mi caso, puse las bolsas donde sé que empieza a filtrase el agua, como va lento, le da el tiempo suficiente para que las bolsas se activen (estás tardaron 6 min en activarse), en otra área de la casa, moví una bolsa ya activada (previamente la moje de 6 min a 13 min aprox.) hacia una zona que empezaba entrar el agua, inmediatamente freno la infiltración del agua, de está manera empecé a poner las demás bolsas y que todo listo, el agua quedó fuera de la casa y fuera en el patio, mientras dentro del hogar todo quedo seco. Quedo encantada. Cuando pasaron la época de lluvia, dejé secar las bolsas en el patio, tardaron en desinflarse entre 5 a 6 meses, leí previamente que son biodegradables, observé el estado del material y, efectivamente, las bolsas se pueden desintegrar o volverse a utilizar para charcos o pequeñas fugas de agua. En una ocasión, tuve una pequeña fuga de agua en el patio sin darme cuenta y una de las bolsas absorbió toda el agua, se volvió a inflar al 50%, entonces, desde mi punto de vista y experiencia personal, estás bolsas se pueden volver a reutilizar pero tener en cuenta que no funcionarán al 100%, nos puede servir para reutilizarlas en situaciones de baja emergencia. Volví a comprar nuevas bolsas con extensiones largas para utilizarlos para las trombas y/o próxima época de lluvias fuertes. Seria genial que las bolsas durarán mucho más tiempo pero, creo que, el material con han hecho estás bolsas todavía no llegan a ello. Espero que, en algún momento, hagan las bolsas con mucho mayor duración.
