How To Install An Inground Pole

An inground Flagpole is simply a flagpole rooted in ground. It is a permanent pole that can withstand wind speeds up to 130 mph. This depends on the flagpole’s material and height. As trees require roots for support and foundations are necessary for inground flagpoles click here.

To make a foundation, you need to dig a hole, then wet the soil and then pour concrete. After the concrete has cooled, a “groundsleeve”, a cylindrical cover, is inserted into it. A groundsleeve consists of a thick steel tube with an open top, and a broad base. It is used to protect the flagpole against the concrete’s corrosive elements. Steel plates secure the groundsleeve in place on its exterior. The inside of the groundsleeve has steel wedges that secure the flagpole at its base. Ground spikes are usually included in the groundsleeve to channel lightning. This might not be an issue if you have a fiberglass flagpole which conducts electricity.

The flash collar can be attached to the foundation. It fits over the bottom of your pole and the ground sleeve. The collar and pole are sealed so water doesn’t get to the foundation. The flagpole must be placed far enough underground when building your foundation to ensure it does not tip over. As a rule of thumb, 10% should be underground. Professional installation may be required for larger flagpoles. Ask the distributor or manufacturer if they are willing to do it free of charge.
