Hi Joe,
You sound like you know what you’re doing, but just in case, make sure to drain, or daylight all that base. If you don’t, the whole thing will fill up with water. Drainage is Key, even more than insulation.

Subject: [papercreters] Using papercrete under earthen floor
Hi all,
I live in
it would be possible to have both a highly insulated floor and
incorporate massive amounts of thermal mass by having an earthen floor
on top of insulating papercrete.
I thought I'd first excavate out the area, and apply some road base.
I'd compact this down. The purpose of this layer is to discourage any
borrowing animals that may tunnel down and wreck havoc on my moisture
barrier. The next layer would be a few inches of sand, then moisture
barrier, and then a few more inches of sand to protect the moisture
barrier. On top of this would be a layer of papercrete for
insulation. On top of the papercrete would be the earthen floor
(presumably of road base). My concern is if I use a plate compactor to
compact the road base over the papercrete, the papercrete would not be
able to withstand it. Has anyone done any experiments of running a
compactor over papercrete? Would the vibrations simply vibrate it to
pieces or compact it?
