Question: 1 / 400

Footings for masonry chimneys must be at least how thick?

6 inches

8 inches

1 foot

Footings for masonry chimneys must be at least 1 foot thick to ensure proper support and stability. This requirement is essential because chimneys endure significant loads and must be built on a foundation that can withstand both vertical and lateral pressures. A 1-foot thickness provides a solid base that helps distribute the weight evenly and minimizes the risk of settling or shifting over time.

This thicker footing also helps in frost protection; in areas with frost heave, a thicker footing can prevent the chimney from being pushed upward or damaged during freeze-thaw cycles. Adhering to this thickness ensures compliance with building codes and enhances the overall safety and longevity of the chimney structure.
