[Greenbuilding] newbie with floor question

[David Field]

Hi All,

I have searched the archives for this with no results.
Is there a way to build an earthen floor that would provide a surface
comparable to concrete for durability and strength in a shop or garage?
Or are there other alternatives to concrete that are strong enough for a
garage floor?

I did find an article on carbon concrete that looked pretty promising, but
it will be some time before it is commercialized in North America, and since
it's petroleum-based, I'm not sure I would want the stuff in or around my
home anyway.

Thanks,
David Field
