Review the walls where the water enters the basement.
Where you see the water entering can be miles away from where it comes through the outside as once inside the block.
Subsurface groundwater under hydrostatic pressure is a serious concern and one that cannot be ignored.
The truth is if water is coming from the floor up as opposed to dripping down walls then it is probably due to a subsurface problem.
It s common for the soil alongside your house to settle over time creating a moat that collects runoff and directs it down your foundation wall and into the basement.
