Post Tension Slab and Interior Wall Anchoring
Posted on 11/27/22 at 2:16 pm
Posted on 11/27/22 at 2:16 pm
All interior walls in my home (load bearing and none load bearing) have no visible anchoring to the on grade post tension slab. I am sure this was to avoid damaging any of the tension cables. Exterior walls are bolted to the foundation.
From how sturdy the walls feel I assume this means the interior walls are glued to the concrete.
Can anyone here confirm if this is acceptable/common? Google has not been much help in this.

When I built a house, the builder went chalked the slab after it dried. I am almost certain the interior walls were anchored to the slab. Of course, the exterior walls all had anchor bolts placed in the wet concrete.

Are you sure there’s no ramset/Hilti anchors? Are you just looking for the bolted j-bolt style used in the exterior?

Nothing that is visible from the top of the sill plate, no little nail holes or anything.

They might not have shot them down yet. Ask the builder

This house was built 10 years ago, I gutted half of it post hurricane Ida. We have already finished installing sheetrock/paint/trim at this point. I noticed this while looking at pictures I snapped during the demo process.
I do have pretty clear pictures, there is nothing there.

Only the exterior walls are anchored with anchor bolts. The framer will nail some plate nails on the interior walls.

Should these plates be visible? Are they driven into the concrete?

Interior walls are anchored with a powdered actuated nail gun.

They probably used cut masonry nails.

That's the residential standard in the US. I don't even know of an alternative method.

The anchors may be recessed under the studs

Hopefully something is there, I sure cannot see anything from the photos that I have.

Based off of this question alone, you need to stop looking at the photos and stop asking questions.
I anchor all interior walls by drilling a 1/4" hole threw bottom plate(treated 2x4 on concrete that all studs rest on) and into concrete and drive in 3 gun nails. Bottom of interior walls only need to be kept from moving laterally.

If they were not anchored, the walls would have moved when the drywall was installed

exactly. if they were not anchored, would have moved and would be able to push at the bottom and make them move.
may have just glued them too, main thing is that they can move laterally at the bottom.
