| I’m totally ignorant with drain tile, we don’t use it in our hills. Need to bury some along some buildings to handle runoff. Wondering if 4” perforated is what I need? Thinking it needs to be buried about 12-18” deep and covered with clean rock, do I still need a sock over it or just the bare tile is ok? Any elevation/slope requirements I should shoot for? How far from the foundation generally? Thanks. | |
