Gazebo Footing Basics

A solid foundation is crucial for the safety and longevity of your gazebo. Footings anchor the structure to the ground, preventing it from shifting, sinking, or lifting from high winds.

Component Importance
Footing Depth Must extend below your local frost line to prevent heave during winter freezes. A common rule is frost line + 6 inches.
Footing Diameter Provides a wide base to distribute the gazebo's weight, preventing it from sinking. Larger gazebos require wider footings.
Concrete Creates a strong, durable, and heavy anchor. The volume must be calculated correctly to ensure you have enough material.
