concrete canvas / cement fabric

I was wondering if anyone had experience making walls / roof tiles possibly out of fabrics coated in concrete. I have seen some old posts here talking about coating old carpet in concrete to make a roof but that post was well over 10years old.

I have recently started using polypropylene landscape fabric (Vevor 8oz non woven landscape fabric) to make some 'planters' that I will be leaving out side over the winter to test its durablity to weathering and freezing.

I have currently tried store bought mortar mixes, as well as straight portland cement also somtimes adding acrylic bonding agent into some of the mixes.

I make a wet slurry mix of concrete in a bucket and just dip the fabric in and shake off the excess

This idea is inspired by:
George Nez's latex concrete habitat

and a youtube channel called: Paradise Builders-Ideas Frescas Ecolodge where he does almost this exact thing to make plant pots

If anyone has done this and has any pointers / ideas or questions feel free to comment

Thanks
