Woot! plane rides, I love those more then road trips!
It's not ruined, it's block. You could dry stack those block and build a house on it, that would last for 40-50 years. I would have it gone over to make sure its sound. Maybe pay a masonry inspector or such their show up rate and have a inprogress (Phase) inspection done.
Not sure what his building code is for his state, I know michigans for block, stone, flashing, grouting, and tuck pointing. But I can bet money that would not pass inspection when those pics were took.
It's hard to find good masons now a days. All the good one are working, the ones that couldn't cut it work cash jobs. Good ones build commercial, leftovers do residential. Their is exceptions to this. Unless your in michigan, our union over priced us right out of work. Think their was 1600 on the local 1 list looking for work still.
Quality control for residential is primarily the builders who build it. Those general inspectors have no idea about masonry code. If they can see flashing hanging out their always happy and sign off. Inspectors we train will take the temp of the mortar being used, check bond, wire every 2 courses (row of block or brick) above grade, make sure below grade (dirt) is filled solid with mortar, check for weep hole, their height, make sure their clean, pan flashing is correct, will look behing the wall for excess droppings, half full head joints, x ray the building to check for rod placement and overlap. The list goes on and on.
Our company spent alot of time and money to put the confidence back into our trade so people will skip the precast buildings. Plus it helps regulate the good company's from the bad when bids start rolling in.
The house will stand on those block just fine. But your going to run into problems 5-20 years down the road, corner cracks in the next year or 2 and them bastards will tell you its normal because the house is settling, yeah right.
