my gh is in a low spot. now this is a small one, but dh dug down about 2 1/2 feet all around the foundation we laid plastic on the ground where the gh will be, then filled with small rocks. around the foundation and pea gravel in the floor area. i found a few pictures i thought i had documented the whole building of it but i cannot find that cd.
this one is the digging of the drainage ditch/foundation.
