Thanks for the reply. In our case it would have been too costly for a system around
the outside – we have a large porch, a deck, and an attached garage that were
all in the way so it would have been a big project. The waterproofing company
warrantees the job for life and seepage is covered. I'll go the route of taking it
up with them to come back.
One more thing – the spots seem to pop up mostly in areas where there are
cracks in the floor. Regardless, the company claims the system is supposed to
prevent water from getting that far because the system collects it and removes it
thus eliminating any buildup and seepage under the floor.
The only real solution is drainage around the outside. You should first
check your gutters to make sure they work correctly during the heaviest
rains and the water should be piped off away from your foundation. Also
check the grade and make sure the soil is graded away from the house
foundation. Also, not only does the top permeable soil have to be properly
graded but if there is a layer of clay below it that needs to be graded
properly too. That is all the cheap fixes. If that doesn't work I would
not spend a nickel finishing the basement until you put in an exterior
drainage system. Quite frankly that should have been done before the
interior basement system. The interior system is really only a back up.
Seems to me you probably have a high water table under your slab and the
basement will never be sufficiently dry unless you get that water table
down. Will probably need a sump pump with a back up power supply.
> Was wondering if anyone out there can lend a hand in explaining what my
possible options would be. I had a waterproofing company come out after
some research and they installed a system with what is called whiteboard all
along the walls. If water comes in it just runs down the back of the
"whiteboard" into the channels under the floor all along the walls over to
the sump. The system seems to be working very well, we've had some heavy
rains and our basement no longer floods at all.
> Usually when it rains I've notice a spot popping up here or there where
it appears to be slightly damp to the touch. I have to hold my hand on the
spot and it feels a little damp. No puddles or anything, just some slight
seepage. The company has been good about coming back out and doing some
work to fix these spots. They ran what is called a "lateral line" one time
that extended a channel into the middle of the floor. On the various spots
on the floor in other places, there was some sort of caulk put in, and I
noticed they drilled a few spots and filled it with this material. On the
second visit, they used more of this caulk material and also some Thompson's
water seal on areas that were larger damp spots.
> My question is should I keep having them come out and treat these spots
as they pop up? I'd like to move forward with putting a sub floor down, but
I'm afraid more spots will pop up. Should I paint the floor with any kind
of drylok or something like that? Also, on that note, are there any
suggestions for a sub floor if necessary? The floor is a bit uneven and
we'd like to just put down some padding and carpet but we think that it's
going to need more than that – something to even out the floor, and
also something to protect the carpet from moisture.
> I do have a dehumidifier running to keep it as dry as possible. These
spots only pop up during rains.
