Hello,

I just bought a house in Santee, CA, known for expansive soils. After
pulling up some carpet, I found 2 hariline 1/16" cracks running across one
of the rooms. ( an addon, which was to code ). The house is 30 years old,
the addon is 8 years old. I haven't pulled carpet from the original
structure yet. The largest width mesaured at any point in the cracks is
1/16". The crack "splits apart' and the sides are totally level with one
over, not an up/down situation.

Is this a concern?

All concrete slabs crack under the right conditions. Both my 20 year old
2 car garage and basement have cracks in the concrete. Not 1/16" wide
though, maybe 1/64". Just enough to see.
Even when sidewalks and patios are built outside, the contractors put
grooves in the concrete to control cracks.

ALL concrete can, and will, crack. That's why they put wire or rebar
imbedded in the concrete - so that when it does crack it won't cause
problems.
