/diy/ - Do It Yourself

Those blocks must be perfectly fine.
I can't get a clearer shot off street view but there are these 2 houses built in the middle of a forest that have sat there for 15+ years with exposed ytong blocks and they are doing perfectly fine, people live in them, I saw lights on last week. I assume they used the block with the circular holes for the RC columns because you cannot see anything but ytong on the outside.
>but how do you know there are RC columns at all
That would have been flattened with the ground a decade ago. Seismically active region, not that much but enough that even sheds get RC columns.
