Anyone see water seepage through the slab?

Hi BP,

I was looking at a house and I found a puddle of water in the middle of the basement floor. Not near anything. Not near the sump pumps, furnace, washer / dryer and there was clean drywall above the spot. It did happen to be adjacent to a lally column w/ footing. Backstory:

This house has 3 (THREE) sump pumps. It has been raining like crazy here and I purposefully went to this house to observe it after all the rain. All the gutters and sump pump spouts are not extended away from the house. The grading is okay with 2 neighbors in a lower position than this lot. I spoke to a neighbor and went into their basement and it was bone dry- they have 1 pump.

I am baffled as to where the water came from. Can water seep up from the basement slab when you have 3 active sump pumps?

Thoughts?

Hydrostatic pressure. Really bad in central Illinois. Not many dry basements around my area right now. Not sure about just using a sealant. Typically a dewatering system will be installed from what I've seen.
