Anchoring a gazebo can be done in several different ways. For example, the standard method of anchoring the construction is to place concrete footers inside the ground and then attach the gazebo to these footers by means of anchor screws. Another method uses threaded rods. By fixing these threaded rods inside each leg of the gazebo and then driving the rods into the ground, the gazebo can be anchored in a rudimentary fashion.
1. Check Your Gazebo
Using concrete footers in the ground is the method recommended by the construction industry's building standards as it is safer and makes for a stronger foundation than using threaded rods. However, it takes a significantly longer period of time, more effort, and is more expensive than using the threaded rods. Usually, it is best to err on the side of caution, but certain types of gazebo can be safely anchored using threaded rods. If your gazebo is particularly heavy and sturdy, threaded rods can usually be used to anchor it, as the weight of the gazebo itself will hold it in place fairly well.
2. Determine Location
Another factor to consider when choosing the type of anchoring for your gazebo is where you will be placing it. If it is being placed in an open area and on soil, concrete footers are usually the best choice as the structure will be buffeted by wind and weather from all directions and threaded rods may not be strong enough. However, for a patio or other paved area set next to a building, threaded rods could be more than sufficient. Check under the paving and if there's a soil base, simply drive the rods into the soil to anchor your gazebo. The building on one side should provide enough protection from the weather that this will work just fine.
3. Drill with Care
To anchor your gazebo with threaded rods, you're going to need one rod for each leg to provide strong enough grip. Whether anchoring them to a patio or on grass, you must ensure there is a sufficient length of rod inside both the gazebo leg and the ground. A set of 24-inch rods are usually adequate. To attach them to the gazebo, take a 1/2-inch drill bit to each of the legs to prevent the wood from splitting, then place the rods about 10 inches inside the leg and drive the remainder into the ground.
4. Dig Deep
When using concrete footers, dig the hole about 14 inches deep into the ground but only pour the footer up to 12 inches. This two-inch gap allows the base to be strong enough, while also enabling you to disguise the concrete beneath your gazebo with landscaping for cosmetic purposes.
