Basement Block Construction

A side view of a common basement block wall you might see in Minneapolis or St. Paul. Typically it's 6'-8' from the drain tile pipe to the grass. The three concrete parts, footing, wall, floor are built at three separate times, footing first, wall second, floor last.
The space between the bottom block going into the floor area is called a "cold joint" meaning wet concrete is layered on dry concrete. This space is notorious for being porous and allowing water to flow through.
Water will enter that central hollow core and when there's enough of it, the pressure of the water column will push the water into the basement floor area.
This is not from a "high water table," it's called "grade level" water. but it looks like it's coming from below the home. Water from a high water table tends to last for weeks, not days.
