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

I'm not 100% sure but I believe there will be UV issues over a period of time. You may want to contact the manufacturer on this item.

I don't think you can. There's a couple of holes on each side but I thing they're for water drainage.

I use these in almost all of my operations. Simply start by putting somekind of bottom layer of perlite or other type of drainage material, then continue with growing fill. Check weight often to determine correct watering routine. They do tend to dry faster than plastic containers buy I like using them.

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!

We are using ours for plants. Yes, we drilled several holes and lines the bottom with pebble rock to aid with drainage

They are as strong as they say they are and remarkably tough. As long as the total rock weight is within the stated limit, the bags will hold up. I would be concerned how you plan to tote the bags though as they are designed to be filled while on the ground and then picked up by a waste management truck.

I would think you could, but beware, as the quality is lacking...these bags are made out of very fine, very thin mesh.

I bought them for my bean bag. While filling it I found them to be possibly light enough for a snow globe but they have a static cling thing going on. I'm not sure how you could stop that from happening. Good luck!

The bags do not come water proof. I was able to "waterproof" them using a 3M waterproofing spray. I say "waterproof" because they certainly will never be fully waterproof (dunked under water). They are a tiny bit water resistant but in a heavy rain they will collect water. If you give them a spray with that 3M stuff you will be good for a while. In edition to spraying them I also used tent seam sealer. I still wouldn't rely on them to be left out in the rain if there were electronics in them.

If you use expandable anchors, they will work fine. These have a coarse thread - probably the hardest thing will be to drill the holes.

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.

If your bags are wider, you can cut them down and seal the edge. If they are narrower, they are usable. You'll probably only seal one end, and your bags won't go the full width of the sealer. It'll be fine!

I forgot to mention that I drill 3 - 5/8" holes in the bottom for drainage when I use them outside...

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."

These bags are horrible. They are for one time use only. It was so hard to zip them closed and the hole for the vaccum is cheaply made. Good luck.

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.

Yes, I'm sure that would work well. They are pretty dense pads so they might not flow a large volume of water through them easily. I tried to run all of my water through them in my sump and it backed up the flow.
