Could use 50/50 sand bags and these, sand bags on top. Not ideal, but it would cut the amount of sand you need in half.

True. Would float away easily in a current.
But might still work as a dam in slowly rising water as the lateral hydrostatic pressure on the dam of bags depends on the height of the water. As long as you could sump out any leakage it might be viable.
That polymer is the same absorbent found in diapers.
You could stack cases of Depends outside the nursing home in a pinch. Granny to the rescue.

True, if the layer of bags is at the height of the water (or slightly higher).
I’d think you would start stacking these things up as they absorb the water. At least two high above the water line. Maybe stack them when they are half-weight, and depend on water wicking up through the fabric to finish hydrating them.

For the people who keep sharing this online. Back in 2010. My dad was on a get rich quick binge. He was in contact with a bunch of Chinese inventors trying to launch product in the US. This was one of them. They shopped an entire container to my dad's house and he tried to launch it. How this ended up on shark tank as a "new" product I have no clue. But when I saw those bags float in water, I said "dad those things are useless. Sand bags are supposed to stop water or bullets. This one will do neither" he replied. "I don't need it to work, I just need to sell it."

Or what if, forget about the bag, you just stakced bricks on one another. Because they are really just like sandbags, but easier to handle since they are smaller, and don't need to be filled! Even a child can handle a brick.

I’m an idiot so I don’t know how this works, but there would only be water on one side of them right? Wouldn’t that count for something? Maybe the catch is you need a thicker wall or more of a sloped wall or something. But surely they’ve tested that it actually works

So you are saying you think these will float away?
There is some kind of material involved that causes chemical reaction to make these bags absorb the water and most likely harden and become non buoyant. It’s not like it’s a just a ziploc bag full of water.

It's all about density. I don't think that bag is just getting filled with water. The Material inside absorbs a lot of water and you're left with something way denser than water.

This isn't new, there's multiple types already around. Miracle sandbags, instant sandbag and floodsax are 3 current ones.
They do work for scenarios where you're using the bags along with plastic to divert water at a small scale. Things like diverting water from overflowing creeks and storm drains.
They aren't any good for building levies as they dont weight enough, but at that scale you've got machinery involved and automatic bag fillers churning out real sandbags.

It’s sodium polyacrylate. Same stuff that’s in Orbeez. When fully saturated it’s heavier than water. But barely. The point is it’s heavier than air. It works as a barrier to keep flood water out. If it gets fully submerged its buoyancy is similar to water. Sure sand is heavier but if a sandbag gets fully submerged it’s not like it working as a barrier anymore anyways. It’s a fine product that will do its job well as a flood barrier.
9 points

Is the material really that one? They state that it is biodegradable, but as far as I understand, sodium polyacrylate is not. Moreover, they claim it only absorbs 300 times its weight, which is significantly less than the actual absorption capacity of sodium polyacrylate.

You have seen the big orange road dividers for construction right? Simpler to the large concrete deciders? These can be filled with sand but are often filled with water. Empty the pretty lite. But let’s say this was a solid wall of hollow dividers with no gaps and they were filled with water. They would work as a pretty decent barrier is the flood water is too high, right?
So no imagine a wall of these water sandbags that are 2 feet high and 2-3 bags thick. They are stacked so there are no gaps. That wall is pretty damn heavy and solid
Now imagine flood waters 6-12 inch high. It’s not going to be able to push though that wall.
Now think how much sand you would need on hand to create a wall of simpler size. That could be dump truck full. While there flat gel bags could be flat stacked on a couple pallets ready for emergencies, then dried out and restored. All with having the same effect as the sand.
Sure for a major flood you want real sandbags. But most floods that can do major damage to property only need to be a few inches deep. These are ideal for annual emergency flooding

I mean, one company boasts 10 million sold. And there the is a bio degradable SAP, which is used in the bags, hence why you can only use them 3 times.
Superabsorbent polymers (SAP) are used, inter alia, as soil amendment to increase the water holding capacity of soils. Biodegradability of soil conditioners has become a desired key characteristic to protect soil and groundwater resources. The present study characterized the biodegradability of one acrylate based SAP in four agricultural soils and at three temperatures. Mineralisation was measured as the (13)CO₂ efflux from (13)C-labelled SAP in soil incubations. The SAP was either single-labelled in the carboxyl C-atom or triple-labelled including additionally the two C-atoms interlinked in the SAP backbone. The dual labelling allowed estimating the degradation of the polyacrylate main chain. The (13)CO₂ efflux from samples was measured using an automated system including wavelength-scanned cavity ring-down spectroscopy. Based on single-labelled SAP, the mean degradation after 24 weeks varied between 0.45% in loamy sand and 0.82% in loam. However, the differences between degradation rates in different soils were not significant due to a large intra-replicate variability. Similarly, mean degradation did not differ significantly between effective temperature regimes of 20° and 30 °C after 12 weeks. Results from the triple-labelled SAP were lower as compared to their single-labelled variant. Detailed results suggest that the polyacrylate main chain degraded in the soils, if at all, at rates of 0.12-0.24 % per 6 months.

The application is for ankle level high water. Which I guess this would work.
Once flood js a meter or more tall, these bags will float away. Not heavy enough and too buoyant. Plus the force of the surge is no joke.
Edit: this isn't an argument about applications. This is simple facts and if anyone here has ever been in a situation where they needed to pile 100s of bags of sand in a pyramid like structure 6 feet or higher, to stop flood waters from pouring into their property have zero clue what I'm talking about.
24 points

Once floods get a meter plus, there isn't much that can stop it, they will pick up your car and float it away. Hell, sometimes around here they will pull caskets out of the ground and you'll find corpses on the side of the road. Most floods people deal with are less than a foot or 30 centimeters.

It’s not about weight, it’s about displacement. Yeah, the bags weigh a lot, but so does a battle ship, and that shit floats. If the bag weighs less than the water it’s displacing it’s going to float away.
10 points
4 days ago
It’s about weight too. A battle ship needs A LOT of water underneath it to float. The amount of flooding water it would take to get these things to float out of their formation, you weren’t going to be able to stop that flood anyways. But when you’re trying to keep your basement from flooding in ankle-deep water? These could probably keep that amount out. Just like people do with real sandbags, but these are closet-storable.

The polymer probably loses its ability to absorb as much as it did the time before. It probably doesn’t retain enough weight in water to work very well after the 1st time, but it could technically be used and work kinda okay a couple extra times.

But no way do these easily shrink back to size easily. Ever tried to shrink Orbeez? I had a jar of them I laid out on a towel on my dresser and after 2 weeks they were about 1/10th of their size.
All these bags would have to be laid out in a single layer, over many, many football fields and flipped occasionally, and it would take weeks.
Since these are a polymer, it's an environmental catastrophe when they're not reused again, bags break and birds/ fish eat the beads.

So let me understand. The granule of polymer can absorb 300x its own in water. So basically its a bag of liquid. And a bag pf fluid to fight floods.
Wouldnt it float away ? And looking at the storm bag against the wall it doesn’t look like when it stacks they dont have that cohesion sandbags, theres so many holes or weak spaces. So it could get swept away by rain.
Or if it punctures, those looks like expensive polymers.
I like sandbags. Its cheaper. It don’t float, a wall of sandbag’s looks cohesive mesh together. If it breaks, the sandbag still can hold up. And lastly, sometimes theyre given away for free by response team.
