Special Condition: Mitigation Question

Queston: I have a special condition where I have a walk-out basement and a
perimeter drain tile that empties to atmosphere through a hillside. (no sump
crcock) My mitigation tech wants to connect to the drain tile to lower the
Rn level in the home.

I can't see this working very well to pull negative pressure from the sub
slab area.

Any recommendations?

Thanks,

Bill Barnes
