Yes, tough to explain without picticures!
Where the water problem occurs is at the back of the house/garage. We
sit on a hill. The entire property slopes
down to the street. The garage is on a slab 8" below the slab that
leads to house. No problem with water on that
level. The garage has a slight slope that tilts toward the the back of
the house, not towards the garage doors.
You are not missing anything. Drain across the back wall is
absolutetly correct. The load bearing wall I mentiond intersects the
back wall.
What the contractors all said, (in unison, I might add)is that the
other walls need drains as well.
If you were looking from above, left wall is an outside wall, so that
would kind of make sense to me.
The one contarctor, as I mentioed, just said, do the ouside wall, back
wall, and 5' up the inside wall.
Are you saying the back wall drain wouldbe sufficient? It's really not
a a lot of water that we get, and it's sporadic at best.


No......I don't know enough to tell you what is right or wrong. My
thought is this: the problem is
with heavy rain and is sporadic. That suggests to me that the slope is
bad and you are getting runoff.
not groundwater. If that is the case, then stopping or diverting the
water so it runs away from the garage
might cure the problem and, at worst, just require a french drain across
back of garage to........? In conjunction
with that, a little grading and/or addition of soil across the back to
minimize what reaches the area in back
of the garage..


The "6" walls come from doing the left, back in garage 1, up the
center (LB wall), down the LB wall, back in garage 2 and 5' of the
inside wall!
Thanks for the input.


Sounds like something that looks great on paper ) Where is the water
supposed to wind after
it is collected?

Being in the epoxy coating business, I might suggest sealing and
waterproofing the wall with epoxy paints. Outside would be best
the could also be done coating the inside of the wall.

very similar to coating sewer manholes - they get coated inside
because you don't want groundwater/surface water entering the
manhole and 'overflowing' the system.
