About this detail

A continuous concrete footing accommodates mechanical and civil pipes running either parallel to the foundation or penetrating directly through it. Sleeves are provided around all pipes passing through walls and footings with a minimum clearance of one inch. When pipes pass through the footing, continuous footing reinforcement is interrupted, and additional reinforcement matching the continuous footing reinforcement is provided around the opening with a twenty-four bar diameter lap length. For pipes passing below the footing, the bottom of the trench must remain above a one-to-two slope line projected from the bottom corner of the concrete footing with a six-inch minimum clearance.
