Time to Raid the Bottle Bank...

My panels are floppy. Its sad but true. They need to be stiffer!
I visited a Textile Concrete factory where they use Textile Concrete to make all sorts of pretty concrete products, including doors, wall panels, and even artwork and sculptures. The textile gives the concrete enough extra strength to be able to sculpt the cement mortar, do you ever remember making papier mache sculptures out of wire mesh? It’s a bit like that.
They were understandably reluctant to reveal their commercial secrets, but we did find that they’d used Glass Fibre mesh to strengthen their Textile Concrete panels.

Since then I’ve got hold of a roll of Glass Fibre mesh from Durban. Fingers crossed it’ll help with the stiffness.

Also I thought hey – woven glass fibre mesh might have some recycled glass in it right? Well apparently not. The mesh manufacturers put me onto the Glass Suppliers. A very helpful bloke told me that their fibreglass insulation is made up of glass fibre with up to 40% recycled content, but fibreglass used for reinforcing mesh must be of a higher quality (no organic material) and so is made using virgin glass. Bummer.
