I agree with doing it right, but it's up to the homeowner, and I doubt she
wants to buy several hundred gallons of self leveler. We decided yesterday to
only do half the basement and leave the workbench area (including boiler)
alone. So now I have a place to put stuff.
In looking at the lally columns, and the disintegrating floor around them, it
appears someone poured a topcoat of concrete onto the original slab. The
lallys sit on the original pour and seem ok, but the topcoat is
disintegrating, and sounds hollow when wacked with a hammer. So grinding would
remove the 2" or so of weak topcoat and holy cow I do not want that cleanup
Pat- the floor is too uneven for scribing sleepers, I'd still be doing them in
