Could you elaborate on the toxins that leach in time from the fake rocks ? Cause i plan to make these walls inside a greenhouse with lots of plants.
I did start to make a few test models and i use a few chemicals besides cement, like synthetic resins for adhesion, a dust like release agent for the molds (maybe it's just talcum powder ?) and plasticizer for the mortar. But these are just a few chemicals that all builders use when constructing a house or just laying down tiles in a bathroom.
Most of what is in these videos you cant find anywhere online since they explain every detail and little secrets of this artwork. I've watched every video on you-tube, some many times over and i still dont know many things about this line of work.
You linked to Zoopoxy, but they use way more chemicals then Vertical artisans, like polyurethane and polystyrene which are known carcinogens.
Concrete is way more natural then the plastic materials most eco friendly people use. Sure the production of it has a big carbon footprint but that doesn't mean we should all build our houses out of styrofoam. I am neither rich nor famous but i think these kinds of things are works of art that everyone should enjoy in their backyard. And if you like DIY like me they shouldn't cost to much.
magine discovering a lost garden with tunnels and underground grottoes buried under thousands of tonnes of soil for over 50 years. That’s what happened at Dewstow gardens. Built around 1895 the gardens were buried just after World War Two and rediscovered in 2000.
The gardens contain many ponds and rills but interestingly a labyrinth of underground grottoes, tunnels and sunken ferneries.
The rock gardens are made up of a mixture of real stone and faced stone using various types of Pulhamite.
