[Greenbuilding] [BULK] concrete vs block vs ___ foundation wall

[Bruce Donelson]

 I would recommend anything but concrete.  Concrete block can make a
great foundation, and lends it self more to the DIY'er, IMHO.

Pouring a wall under an existing house sounds like a logistical problem,
compared with placing blocks.  Would you jack the house up too high,
then let it back down on the concrete wall? Would there be room for the
concrete truck to swings it's chute between the top of the wall and the
house? I dunno.

I've done a few of each, and I think that the poured concrete foundation is
the easiest. A block job still has to get the cells poured, so you need a
concrete truck either way. A pump is pretty much required for an existing
house. If you can raise the building up higher, then set it back down, it
makes it easier, too.
