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 ?

This video is a builder in AZ. I'm in NV. I had never seen this
construction or knew about it until after I bought the house.

Stick built and stucco exterior. Never have had a crack in the
drywall.

Never heard of it in residential either. I'll be gol danged.
I bet that jumps the price up.

They just do mono slab here (or slab over stem wall). There is a 16"
deep (total) ring around the house with 2 #5s in it and a 4" slab
across the floor with 6 over wire in it. If the ground was properly
compacted, that ends up being plenty stable. I have terrazzo over than
and there are no cracks here after 53 years.
The stucco over plywood is far more troubling, particularly around
penetrations like windows and doors. A couple companies in Atlanta got
their ass sued off over that.
Here it is usually stucco over block. By the time you buy all of the
hurricane clips for stick built, block ends up cheaper or at least
comparable. You basically have to clip every joint where the sticks
meet on every load bearing wall and post and anchor that to the
footer. In block construction you just dowel the cells every 4' and
pour them solid, then you pour a tie beam on top (with 4 #5s) and
embed clips for the trusses. It goes a lot faster.
The 2400 sq foot house they are building around the corner went from
pouring the slab to truss in less than 2 weeks. They lost some days
for concrete set and inspections too. The block crew was at tie beam
in a day after the slab set.

My exterior walls are 2X6 with wire and stucco. ~20 years old with
very minor hairline cracks (very, very few) around a couple of
windows. When I added the patio cover years ago, there is only one
small crack so far. The ground here is like hard pan dirt. For some
reason they make you dig it all out, compact it and then poor the
foundation...

My other three homes I used to own were not cable tensioned
foundations. Same type stick and stucco.

These clowns out here don't use rebar or wire in a 4" driveway pad
like back east -- mumble mumble :-)
