During the last rain (it rained for a week) I found water in the
basement (quite a bit) and found the source. The white colored plumbing
is laid inside another black colored tubing as it goes to the outside
and the water leak was coming from narrow gap between the plumbing and
the outer tube. The builder hadn't sealed the outer tube very well on
the outside. Repeated calls to him left unanswered. I obviously don't
want to dig up the ground on the outside to look for the plumbing tube.
Is there anything I can do inside the basement (perhaps push something
through the narrow gap) to seal it?
Yes, once it dries out. That space should go completely through the
wall. You can use a good silicone caulk in there. Excavation on the
outside would be unnesecary in my opinion. Trick will be getting the
caulk deep into the hole. <grin>
Somone might recomend hydrolic cement, I think thats the wrong thing to
use in your situation as I understand it.
Now, this shouldn't have leaked, even unsealed in my opinion.
Check you outside grading. Is there at least a 1/4" per foot pitch away
from the house?
Check your downspouts. Do they carry the water away at least 4 feet, 6
or more is better, best is to a drywell or culvert?
Here in New England, the recent rains caused many basements to get water
that never had water. I know of one house that was dry for 40 years got 2"
of water, another that was dry for 20 years got 3 feet. Never had any at
work but we got 18" in our plant. First time since the hurricane of 1936
Yes, unusual circumstances for sure. We had 8 days straight of rain
where I am as well. Not as far north as NH. Still my basement is dry. I
have gutters going underground to a drywell which overflows into a
culvert at the back of the property plus proper grading. Those things
are key to keeping things dry. Neighbor had 2 feet of water in his
basement. He does not have proper grading.
