[RE-wrenches] DPW concrete base

[Dave Angelini Offgrid Solar]

I wish I could do that William. Most of the Offgrid places I go would be
too expensive/time consuming to even consider driven pipe.
The biggest mistake that people make when re-enforcing concrete with steel
is not elevating the steel above the ground. This can be a path to rusting
out the steel long before its time. We very rarely need Pro engineering
offgrid as long as we stay away from roof mounted solar. I always have for
offgrid! I save the roof for capturing rain!!  Cheers !
