Hello. I have water finding its way in one corner of the basement and I am not able to trace exactly where it is coming from. I see no visible cracks on the walls or flooring and I have extended the downspout in that area of the house. Still seeing water when it rains and a small puddle at all times. I intend to make temp partitions on the floor to isolate the cause. Water could just be accumulating in that corner but that does not necessarily mean it is coming from that corner.
