spose its relative to your climate,

for the best job out here we lay out heavy duty plastic on top of the dirt to prevent moisture sweat in the winter, then roto hammer the outside walls and install re-bar through out and tie it all together, then they have some kind of concrete blend that has fibers in it for garages, they turn out good and they never crack or get wet.

next one I do will be painted..they sure look cool painted!!!
