The wood on the walls is guides to help level the hempcrete as it is sprayed. They will be removed as the spraying happens when each bit is done so that the hempcrete covers the whole wall. It is slow progress fitting them as they all need to be carefully levelled so the wall comes out flat.
Working round the toilet and wires is quite tricky. The wires on the walls will be buried, but the ends all need to be free to go and connect to things.
At the bottom left here is the frame for the toilet with a wood surround which will remain because the frame is deeper than the hempcrete.
We discovered that they need 6000l of water on the day. I guess some of it is for cleaning the machine, but not quite sure - 6000l seems a lot. By my calculation it would be 6cm of water on the wall (if it could stick there). The depth of the hempcrete is going to be 8cm so it would be pretty saturated.
We have bought some 1m x 1m tanks which (obviously) contain 1000l each - and we will buy a couple more. The rest is in pil drums and the water but from the garden.
