Below picture was taken while in the crawl space last fall. Notice that the
floor joists
are even or below the top of the block. The elbow you see is from the shower.
Notice
concrete block has been knocked out to allow for the pipe.
Same area, different shot.
Taken from above after removing floor.
This is a shot of the same area after jacking up wall, and putting in
treated plate, joists and end joist. Actually raised up over 2 inches.
