New basement cracks found on concrete floor and poured walls after changing and adding one dehumidifier
Thank you. 

I have been following up on the cracks, they have stabilized.  I had a basement structural engineer review them along with the integrity of the walls and floor, no structural problems.  I used a joint/crack concrete sealant laying down a backer rod first which has remained unchanged.

May have pulled moisture too quickly with changing to 2 more efficient dehumidifiers as no cracks were noticed prior to this change.

Using concrete sealant to decrease likelihood of additional drying/crackingof concrete.
