Pipe Penetration and Clearance at Concrete Footing

About this detail

Concrete footings require specialized detailing when mechanical pipes cross their path either above, below, or directly through the foundation element. Sleeves are required around all pipes passing through walls and footings. When a pipe passes through the footing, continuous footing reinforcement is interrupted, and additional reinforcement matching the continuous footing rebar is added around the penetration. When a pipe passes below the footing, standard footing steps apply if dimensions exceed one foot six inches, maintaining minimum clearance dimensions and lap lengths.
