A house that I'm thinking of buying has a number (20 or more) of what appear
to be 2" in diameter holes drilled in various locations or the basement (800
sq. ft) and then recemented. Someone took the time to mark them sequentially
with numbers ("X13", "X16", "X20" etc.) The only thing I can think is that
someone was either testing for something or possibly trying to level the
floor. The floor does show some minor to moderate signs of heaving, maybe an
inch out of true in the worst spot. Any idea what these holes would have be
used for? The current owner hasn't a clue either. Thx.
Basement floor is sort of floating concrete pad. They are not attached
to the walls. It can rise and sink. Maybe it was sinking unevenly?
Mud jacking will raise it up or prevent further sinking. I had it done
once on my back yard patio pad. Just a guess though.
If they are poured correctly, the concrete is poured so that at least
part of it lies over the footings, therefore it may rise, but it will
not sink unless it takes the footings with it, or it cracks and sinks
inside of the footings.
Everything that we wanted, at our price range, was included in the
plans. We did not have to settle for a house that had some of the things
we wanted and other things that we did not want.
It's like ordering a new car to your specs, and not settling for a car
on the lot that was close to what you want.
maybe its the sort of 'X' marks the spot
could be riches under them spots
could be ashes of x-wives
I watched them pump concrete under a neighbors two car concrete pad
driveway/carport - this whole area was parceled into a subdivision and the
guy that cleared all the palmetto's and pine trees would dig holes about
every hundred yards and bury the foliage... which over timed
rotted/condensed and many homeowners driveways and yards have slowly
developed deep wavy, wash board style sink holes. Anyhow - The neighbors
carport slab was cored about two inches dia hole in several spots and they
pumped concrete under it to lift it back to flat, mainly to fix the forever
shifting/tilting/sinking roof.(for a few more yrs)
