Lecture 35 - Page 1 of 9 Lecture 35 – Wall Footings All structural load-bearing walls must bear on footings. These footings in turn distribute the loads to the soil. If the loading on the soil exceeds the soil bearing capacity, undesirable settlement will occur, resulting in cracked walls, uneven floors, or potentially structural failure in extreme overloading. Wall Footing Requirements : 1) Must distribute the loads evenly to the soil. 2) Bottom of footing must be deeper than the frost penetration or else frost heave will occur. 3) Must be well-drained to prevent wash-out. 4) Must bear on undisturbed (or engineered) soil.
