    Hello all,

    I have a new construction house under way (in Florida). It's still in the
    rough stages (walls and roof up, plumbing and wiring mostly done, no
    sheetrock yet). Today I noticed a crack (narrow, almost a "hairline"
    crack) running for about 15 feet across the slab. Is it somewhat
    normal/expected to have a crack in the slab, or is this a very big warning
    sign that I should bring up with the builder? Thanks for information.

    Small cracks are normal

    As Don Young says, some hairline cracks are not unusual and joints of
    several kinds are used to control cracking. Concrete changes volume as
    it cures and if the soil is not properly prepared, can settle.

    The size, shape, and location relative to other features can give
    useful information on causes and severity.

    Dan,

    As the others have said small cracks are inevitable however you may want
    to fill them with rubberized caulking if they widen anymore, prior to
    putting down your finish floors such as carpet. Doing so may deter ants
    and such from appearing later.

    Thanks (and also to the others who replied)! I guess I'll not worry too
    much about it. Appreciate the help.
