Slab reinforcement

[Bama dav]

506.2.1 requires fill to be approved when more than 24in.Seems like I remember an exception a few codes back that allowed for no.4 rebar 24" on center each way instead of compaction? Maybe my old timers kicking in! Does anyone else rember that exception ?

Bama dav,

That's 24" of sand and gravel, and only 8" for dirt [ `06 IRC ].

Is yours the sand or gravel flavor?

Most of the time it's gravel.just really wondering if the exception was my imagination or something that has been changed.

I checked the `03 IRC, ...the `00 IRC & the `97 CABO

for 1 & 2 Family Residences......That section is the same in

all editions.

The CABO 1975 edition states the same, 24" maximum lift for clean sand or gravel and 8" for earth. No other exceptions listed.(R-603.2).

It would have to be built like the second floor of a parking garage in order to forgo compaction.
