Have you seen gabion baskets made with used chain-link fencing?

I have not, probably because it’s heavy for making corners. So, make them oval.

I think that chain link is a little too flexible to make gab-ion baskets... gabion are usually made with a heavier welded wire.. so it holds the shape.

I’ve not seen gabion stacked, just varied heights. You can still use square or rectangular tops.

this is is a curved wall, but if you Google or Pinterest “gabion”, you f8nd more ideas and instruction than you can possibly imagine. Including round Gabon for girepits.

Nice way to think out side the box. It could look amazing. Since chain link is so floppy would need a strong support frame, either the same pipe frame it was hung on or something new..... wood or...? With the right type of frame you could create a very dynamic, flowing feature wall.

Maybe use galvanized wire internally to hold the shape

I built a dock out of old chain link fencing that has a rubber coating - probably the worst type of fence to use. It's in a canal with an immediate slope of a bit less than 45 degrees. I made the baskets 2 feet deep and 4 feet square which makes it sticks out 8 feet in total. The canal is lowered in the winter which allows me to walk all the way around it to make minor repairs and adjustments. I avoided bulges by putting wire across the insides while I was filling the baskets. For fill I put large rocks around the sides to hold in smaller fill in the interior. I used bricks and concrete chunks and broken patio stones - anything I could get for free. It has lasted quite well for 4 or 5 years. Many creatures live in and under it - snakes, frogs, small fish, crayfish. It's not perfectly square like perfectionists might prefer, but it is solid and a good place to fish or dive off of.

I have a bunch of 3-foot chain link and have been thinking of making a quasi-gabion retaining wall by creating a bunch of 3-foot diameter cylinders of cyclone fencing and laying them out squashed together on about a two-foot spacing making approximately a 4-foot deep wall with an undulating face, and rear, kind of like the sides of an egg carton. I'd tie the abutting sections together and count on the hoop stress, the circumferential stress in the chain-link cylinders to create a very strong wall. I believe this wall would also be strong even utilizing round river rock due to the bowing of the face being part of the design.

I suspect this same design could be done with a 6-foot chain-link also, or whatever height one has available. Chainlink is heavily galvanized for longevity and is quite thick gauged so is strong, but only when stretched so as long as the design stretches the cyclone fencing I think it would work very well, and even with non-angular fill.

P.S. I had no intention of tops or bottoms as the shape would be held by the ovally cylindrical shape, not by tie straps and tops and bottoms, so potentially a faster install.

Chainlink fencing? No! but it could be made with wire fencing. Cut to size and wired at the corners.

It has been used to make a gabion basket retaining wall.
