Folks,
Am wondering what everyone thinks about using either crushed limestone or crushed concrete for backfill into the holes of a polebarn style garage I'm planning on building this summer. I've come to the conclusion that most feel filling the holes with concrete is a no-no, though I see commercial buildings who do. I plan on sinking my poles(haven't quite settled on 4"x4" or 6"x6") about 4', mainly do to higher winds we can get here along the coast.
