A gazebo gives your yard an extra sense of charm and whimsy. However, improperly anchoring the gazebo can turn a functional addition into a construction disaster. There are a number of different ways to anchor gazebos, but concrete is one of the most reliable. If you plan to put your gazebo in an open area that is susceptible to the elements, you need to use concrete as it is the most stable way to secure the structure. Many people choose a concrete anchor regardless of where the gazebo is located just so they have peace of mind.
Anchoring a Gazebo When You Pour the Concrete
Choose a location for your gazebo. Remember, the more the gazebo is exposed to wind and other elements, the more securely you want to secure it.

Drill 1/2-inch holes in each gazebo leg for the thread rods. The 24-inch rods are enough to provide a stable base for your gazebo. Put approximately 10 inches of the rod into the gazebo leg.
Dig a 14-inch hole for each gazebo leg.
Pour about 12 inches of concrete into each hole. Mix your own concrete from cement and sand, or you purchase pre-mixed concrete and add water. Both options are viable and hold your gazebo.
Secure your gazebo in the concrete holes and allow the concrete to dry.
Landscape your yard so you cannot see the concrete. The extra two inches you allowed in the concrete holes give you an opportunity for creative landscaping to hide the concrete bases.
Anchoring Your Gazebo in a Concrete Slab
Use a 3/16-inch concrete bit to drill a 1-inch hole in each the concrete for each leg.
Insert a 3/16-inch pin grip concrete anchor through the hole at the end of each wall anchor plate, which is found on your gazebo. Hit the pin grip with a hammer to secure it in place.
Secure the pin grip into the holes in the concrete slab.
