Our neighbors have had problems in the past with water in their basement. They put a sump pump in, but the silly thing runs pretty much constantly.
The slab is cracked bad in some spots.
They decided to have it all redone. The old slab removed, and perimeter drains installed.
The work crew that is doing the concrete work, removed the old slab, and the plan was to remove 12 inchs of dirt under the old slab, fill that area back in with a good base, then repour the new slab. They also discovered that becuae of the ground heaving in the past,,the main drain was broken and split in two.
What hashappened now, as they have dug down the extra foot, there is water seeping up and this morning , there is 1" of new water standing in the dirt..
You guys that work concrete,, have you ever encountered this?
Who would you call to find out where the natural water table depth is?
The concrete forman says he has never seen this, and HIS paln is to fill most all of the area with 1" rock, then follow that with the new base..
