    Cool more about non-load bearing wall & mudsill

    Dear Sirs,

    I posted earlier about the mudsill, which I
    thought was disintegrated.

    When I looked into the wall I saw the stud and
    the sole plate, which sit on top of a parallel row of
    cynder blocks. The joists apparently run
    parallel with the wall so it is non-load

    How is this type of wall constructed? Is
    the subfloor laid on top of the cement (cynder)
    blocks and then the sole plate and wall nailed to
    the subfloor? I only have the hollow cynder block
    with a stud and sole plate. There doesn't seem to
    be an anchor (or a 2x6)).
    How is this edge of the subfloor connected to
    the cynder blocks (non-load bearing)?

    Here is a small drawing:

    ________________________ <outside foundation wall
    ll____________________ < wall in question (cement blocks, sole plate and stud)
    ll xxxxxxxxxxxxxxxxxxx <rotted, so edge of floor is no longer supported by concrete blocks
    ll_________________________________________ outside foundation

    The roof valley leaked along this "wall in question". Now the
    wall stud has rotted and the subfloor has come loose from the
    concrete blocks (like a pier) so the decking sags in the corner
    where I've placed a red x.

    It looks like the subfloor (decking) rested directly on the concrete
    blocks of the "wall in question", but maybe the 2x6 has just rotted away. These are hollow
    concrete blocks, which don't have any cemented anchors that I can see.

    Sincerely, Paul serapions@yahoo.com

    Thanks, Paul serapions@yahoo.com
