Backfill
I have protected all mud floors with total backfill. I first placed strips of plastic sheeting to mark the boundary between the ancient surface and the recent dirt, and then placed a stratum of about 20 cm of dirt, derived from the excavations, on top of the entire surface of the mud floor. At the edges, along the base of the walls, I have placed a small berm, about 25 cm in height, in order to protect the base of the wall from infiltration of the water when it settles and forms a puddle across the entire surface of the space contained by the walls.
