If the slab most common in a home has post tensioned cables inside,
thats a severe safety issue. my brother had this come up in his home,
a below slab water line broke, he had to have his slab x rayed
to avoid hitting any cables.
I doubt this is a issue for the OP but might be a issue for someone else


My foundation is cable tensioned. You notice a cable (s) sticking out
of the foundation an inch or less --- not in all cases, though. Some
home builders put a stamp in the garage pad to indicate the slab is
cable tensioned (no all do).
It is worth knowing before you cut the concrete. I was lucky we
missed the cable in a master bath reno.


Here's a " Learn something new every day " moment, for me.
I had no idea that this was ever used in homes !
Is it used for certain special cases ? like no proper footings or
architectural design .. or something ?
