Thanks for the links.
Not adding any new openings, had to cut down the top of wall for a mudroom addition. New foundation walls will go down to bottom of existing footing so no new pressures will be added to wall.
Has anyone run into this particular unit before and have any information on block sizes, compressive strength, etc.?
