Not sure of home age(no records) though a toilet dated me back to 1957 However on initial walk through I noticed a temp jack in place and decided to remove a few ceiling tiles .
This was lower level of home on a slope and under the garage.
Turns out they ran a floor drain and cracked the hollow core concrete blocks to do this.
I am unfamiliar with this type of floor structure so can anyone help me out on the integrity/repair and history or explanation of this type support for the garage pad.
(side note) 100 mi round trip and I am going back there today because I forgot something meaning if a new picture is needed let me know now.
Makes me wish we could do a live video while talking (Skype style)
