[Cob] NEW EARTHEN FLOOR ON OLD CONCRETE FLOOR

[Clint Popetz]

Earthen floors are much heavier than floor tiles.  Like any change to
an existing structure, you'll need to calculate the change in dead
load and see if your floor joists can handle it.
It will depend on joist depth, spacing, and maximum span.  It will
also effect your bearing wall (assuming you have one), and the beam
that supports that wall under your house and the columns that support
that (unless you're slab-on-grade.)

It's a question for a structural engineer or architect.  Honestly.

And can it then be finished off with linseed oil and sealant if the person is actually living in the townhouse?  Can it be done on a wood staircase?
