Where is the troweled repair? The block on the right side of the picture with the horizontal lines?
If those are 16x8 block then they were installed by a novice, the edges of the block should rest on the (middle) webbing of the block below. Some of the vertical joints dont appear to line up in the middle of the block below.
Are the jack pictures of the same house? Who could think that would be a good idea?
at least that’s actualy a HOUSE JACK. not a car cack. still only for use to jack the house, and remove after properly supported. i’ve seen tons of these in use up here as cottages are turned into yr. rounders. i grew up down the street from i guy who now does that for a living. he’s got a 6 jack hyrolic set up that can life a house 6" in 1/2 hr. (after set up.) then block it, jack it, block it, jack it, and after 4 hours, ONE guy lifts a house 2 feet for a slab dig and pour, etc. pretty cool to watch too.
