My unfinished basement currently floods after heavy rainfall, even after
paying a professional waterproofing contractor $4200. Since I have I life
time guarantee, they said they may need to create a trench around the inside
perimeter of the basement wall and drain the water into a pump.
The contractor said they would use a jackhammer on the edge where the walls
and floor meet to create this trench.
Now, I have some questions about this ....
Would all this pounding cause damage to the house since the drilling is done
so close to the foundation footing?
Also, later on, I'm thinkiing about covering my unfinished basement walls
with drywall. Would moisture and mold develop between the basement wall and
Any advice on this would be appreciated.
If you paid 4200 what did you get, it seems as if your lifetime
warranty is being tested, are they going to do the work for free. where
does the water come in. How high is your water table ,If it floods only
after a rain grading and your gutters may be an issue. Im not sure an
interior drain is the right thing. mold will be a problem until it stays
Sounds wrong. They should cut with a concrete saw then just break up
the narrow piece with sledge hammers.
I don't like it. I've never seen anyone do this with a jack hammer.
Different question. Put a moisture barrier up before putting up the
walls. That will keep the water out of the walls.
If they plan to put in a sump pump, insist on a battery backup for it.
Power is most likely to go out when you need it most - in a storm.
Possibly -- the vibrations could trigger cracks in drywall seams,
possible other problems as well.
Cutting with a concrete saw and then using a sledge and undermining
the trench is more common.
Unless you've got a high water table ... I would expect the fix to be
on the outside rather than the inside.
Yes. Get your moisture problem solved first.
It is now code (at least in many places) to use a moisture barrier
against all below grade surfaces. Then, studs, insulation, vapour
barrier and drywall.
