Pipes passing through concrete foundation walls and grade beams require a sleeve with a one-inch clearance all around. One number five reinforcing bar at twenty-four inches long is placed above and below the sleeve in foundation walls and grade beams. Pipes are prohibited from passing directly through footings or grade beams. Where a pipe is located less than twenty-four inches below the bottom of the footing, the footing is thickened and extended a minimum of one foot on each side of the sleeve.
