When you say drill, your talking about under the slab into the dirt right ?
Im guessing home depot has these 20 foot extensions ? im already having
decent results with only about a 3 foot penetration. But your method seems
more logical.

Dirt grass...you mean something like hay ?

I was thinking about cutting out a wire fence just underneath the hay so no
animals get caught in there....or decide to call it their home.

say its part of a underslab drain. just dont talk about what its
draining

yea, but they'd probably ask..

Something I just thought about... when they run the septic lines...they dont
run them under the foundation do they ? Trying to think if theres something
under there that I might hit with the drill. Because the whole is pretty
close to the septic pipe. Im just not sure exactly where...doubt it would
be under the foundation right ? Probably a super noobish question.
