11 years ago I star drilled a hole through 8 inches of concrete in my
basement wall to put telephone line completely underground as it was
part of my home security system (which calls out to police if alarm
activated) as telephone was underground up to outside of house wall. I
thought it was dumb to have the phone line exposed as all a
knowledgeable thief had to do was cut the exposed line to prevent alarm
system from calling police.
I'd sealed the hole with calk sealing compound around wire as suggested
by my local hardware store from outside & inside before filling the hole
(about 3 feet deep in clay soil---tough to dig and not damage
underground phone wire).
It has remained dry for 11 years. Now, 11 years later a small leak has
developed (only in severe prolonged heavy rain) around the wire, small
drip but over time enough to wet the wall and floor.
Our soil is high clay content and likely holds the water for longer
retention. Slope is away from our house, and leak subsides with a day
if rain stops.
What can I do to seal the hole/wire where it comes into basement and do
all this from the basement side?
Not happy I made the decision to bury the wire entry hole so deep (about
3 feet) 11 years ago, but too late now.
