Are these bags permeable? Can I use them to build short retaining walls?

they are pretty thin. i would at least double bag each one. i would be cautious using them in areas that get a lot of hot summer sun. i think it would break down the material fairly fast. Army surplus stores, if you can find one, typically have stronger sandbags for things like retainer walls. i bought these cheap ones off of Amazon to fill inside my bigger (heavy 70lb.s) army canvas sandbag that i use to workout with. hope this helps.

I don't know if you can build retaining walls with them but yes, they are permeable. Water passes through them.

There r some what water proof but I had to use 500 pound of sand to fill them

They are permeable to water but not sand. They could be used for a retaining wall, IMO.

I haven't tried that but I would say yes. They will actually pass a tiny bit of sand through so I'd assume that water would pass OK, might be slow.

They are permeable. I filled while my sand was still wet from rain and some water came through into the bucket I was using to steady the bag. You could probably use them to make retaining walls if you would like?

I don't thinkt hey are waterproof, so no, water wouldn't be a viable fill material.

I have no knowledge of how a large wall of these would work for a rising river. I have only used these to prevent water seeping into my basement, not something on such a large scale as river flooding. The bags are heavy when filled with water and would be quite messy if covered with mud and debris.

I do use bags, but the pail is made like a bucket and wouldn't leak with water in it.

No, The bags must be Vacuum bags. They have a special texture on the inside which allows all the air to pass through and vacuum to be applied throughout the bag. They are made of a material which is non-permeable. so they do not allow air to get in. However, they work on Ziploc brand vacuum bags. they are cheap and great and very tough and long lasting.

You should not flush these bags. They wont break down fast enough for most water systems.

The bags are a heavy unlined canvas and have a fold at the top with velcro that keeps it tight. If you filled them with water it would leak through the bag and the top. I'm assuming your wondering about water so you don't have to carry the 40lb bags of sand around. I'm thinking if you could find some kind of water/liquid bladder that you could slide into the bags then then fill with water. You may want to check into a sporting goods store, but that option may be quite expensive especially since you would need 4 of them.

Absolutely NOT. These bags are not suitable for food or perishables. They are not air tight.

These bags are NOT compostable or biodegradable! Earth friendly they are not either as they use a chemical to break the plastic down faster...From the company: "Our bags are are neither. We plan to have a 100% compostable line in the next couple of months so check back with us."

Sorry it took so long to answer, I hope you found your answer by now, if not, they do have drainage holes in the bottomthey are very nice, I can't believed what I paid for them. I hope this helps. Bye! b

You're correct, they would not be beneficial. Only other suggestion is using sandbags (long tube type used for weight in the back of pickup trucks). You'll want something to keep it steady. It'll probably 'walk' on the concrete when being used. Good luck!

They are designed expand when put in contact with water. My bedroom door to the patio leaks, so that means the water still has to come in before it activates. This also means I have 3 black bags laying on my bedroom floor. Better practice is to build a V shapped dam on the outside door so you will deflect the water, keep the door still clean and use the door. Also note if you open the bag and you live in a humid put out all 3 bags. You can't save it for later. I love these sandless sandbags!

Yes....as opposed to BioBags which are .8 mil thickness, these are 1.0 which makes a big difference in how long you can go without it leaking or tearing.

These are not self sealing. These bags require use of a bag sealer or tape.

Your sealer is made to use with reuseable bags with vac port built into bag. So yeas you are correct, these won't work

Not to burst anybody's bubble, but I would NOT recommend making holes in your siding. You run the risk of getting moisture back in there which over the long haul can damage the infrastructure of your house, necessitating very costly repairs.Find somewhere else to hang these.

I would think you could. They work very well and are lightweight to move. They do stay filled quite a while once activated and you may need to adjust how they are stacked to balance. They keep the water well away from your house during flood weather.
