Earth floor (sol en terre)

A few weeks ago we made a start on the earth floor downstairs.  I am using the book 'Les Sols en terre' by Marie Milesi and Johannes Riesterer as a guide.  So it will be two layers of earth laid onto the existing layer of volcanic rock (pouzzolaine) followed by coats of flax oil and possibly a tempura paint ...

The mix we decided on for the subfloor consists of clay earth (12% clay content) that came from a neighbours land, sand 0,4, a gravel sand mix (mélange à béton), some chopped straw, bark chip and flour glue ... it has cost around 60 euros so far for the materials ...

Some images of the work so far:

The Ingredients/materials

Flour glue - a handful for each concrete mixer load

Mélange à béton (gravel and sand mix)

Chopped straw (we used the lawnmower to chop
the straw so that it could be used in the concrete
mixer - if the strands are too long they get tangled
on the mixer blades ........ the ideal machine is a
malaxeur planetaire (don't know what that is in
English) - it is a machine with horizontal action
blades - but supremely difficult to find ....

Bark shreddings/chips collected free of charge
from a local saw mill ...

Local sand - 0,4

Lauren using the level taped to a builder's ruler
to level the floor ... ideally we would have
used a lazer and vertical sticks wedged into the floor ...

the floor mix
