[Shop-talk] Options for carport floor?

[Jim Franklin]

The house I just rented has a covered and walled carport as a  
"garage". I have permission to insulate/sheetrock/wire it to be usable  
as a winter motorcycle repair facility for my neglected children. The  
floor is a mix of earth and gravel, and much of the structure rests  
right on the earth.

Are there any cheap and easy options for getting a harder and flatter  
floor for something that will be infested with termites in a few  
years? It needs to support a car during snowstorms. It's 600 square  
feet so even cheap cast concrete pavers will be out of budget, which  
is about 50 cents/sf. I'm not hoping for much...

thanks,
jim
