Gabion fill

Definitely not an option. No access at back. Would need to be transported from front to back and then somehow dropped into place. That would in itself be another head scratcher.

Looks too structural engineery to me ?  but thanks for suggestion.

I like the criblocks. Though proving difficult to find anywhere that just sells them on their own for say something like my domestic project (small scale). I could be proven wrong here. Might have discovered a gap in the market! They come in concrete, plastic (recycled) and timber. Stumbled upon one site that gave me rough estimate for my 30m3 wall - came close to 10k!

Looking like gabion is still the most cost effective for want I want.
