If you’re installing one of our residential telescoping flagpoles, you don’t need a massive concrete footing or a truckload of concrete.
For a typical installation, we recommend approximately three 60-pound bags of concrete mix.
How Big Should the Hole Be?
Our installation instructions call for a hole approximately 30 inches deep and 18 inches round. Before adding concrete, place 6 to 8 inches of small gravel or crushed rock in the bottom of the hole for drainage.
The basic installation is simple:
- Dig the hole approximately 30 inches deep and 18 inches across.
- Add 6–8 inches of gravel or crushed rock.
- Place the included PVC ground sleeve into the hole.
- Surround the sleeve with approximately three 60-lb. bags of concrete.
- Use a level to make sure the sleeve is perfectly vertical.
- Allow the concrete to set and cure overnight.
You can see the complete process in our telescoping flagpole installation instructions.
Why Use a Ground Sleeve
Our telescoping flagpoles include a ground sleeve for installation. Rather than permanently setting the flagpole itself into concrete, the sleeve is secured in the concrete and the flagpole fits inside it.
That makes for a secure installation while allowing the flagpole to be removed later if necessary.
Don’t Forget the Extra Bag
Three 60-lb. bags is the approximate amount required, but concrete is inexpensive enough that having an extra bag on hand isn’t a bad idea. Hole dimensions can vary slightly once you start digging, particularly in rocky or loose soil.
More importantly, don’t reduce the size of the foundation just to save a bag of concrete. A properly installed foundation is what keeps your flagpole straight and secure when the wind starts working against a flag 20 or 25 feet in the air.
