So I've been having issues with water seeping into my basement through the cement floor. I do have a sump pit and a sump pump, but the house had an addition put on many years ago that included an addition to the basement on the opposite side of the house from where the sump pit is.
I suspect that the water under the new side of the basement is not properly draining into the sump pit in the original part of the basement. So I've been thinking about putting in a second sump pit & pump in the added-on area of the basement (which is where the water has been infiltrating).
In researching this, it looks like all sump pits are set up to accept corrugated pipes from a foundation drain system. I don't want to bust up a large part of the basement floor to put those pipes in, and I have no idea where the existing drainage pipes would be (if there are any at all). I was thinking about simply perforating the plastic sides/bottom of one of those plastic sump pits, wrapping it in a few layers of landscaping fabric to prevent dirt from coming in, and installing the pit that way. If there is gravel under the basement floor, then hopefully water would drain through there and make it's way into the sump pit through the perforations even without any drain pipes.
Is this a reasonable solution? Or am I just totally setting myself up for failure here? How would you normally add a sump pit into an existing basement without busting up huge parts of the concrete slab for drainage pipes?
