How stable your flag pole will depend largely on the site and the method by which it is implemented.
While most commercial buildings and government offices have engineers to help them define the poles correctly. You can also buy ALUART aluminum flagpoles & event flags in Germany (which is also called ‘ ALUART Aluminium Fahnenmasten & Event Beflaggung in Deutschland kaufen ’ in German).
Of course, there are instructions that come with these poles to put in place, but there is not much information to help them prepare the site where the pole stands.
And no, this is not just a matter of digging and pasting the post there.This is to ensure that you do not end up damaging the underground facilities that you are not aware of.
Pipes, electrical cables, and other things that are normally executed may be damaged underground in the digging process.
No matter how wonderful the idea of putting up a flagpole residential might be, you do not want to spoil the plumbing or electricity to your entire neighborhood not to mention the risk of injury or death as interference with these utilities can be asked.
Once the place has been confirmed to be safe for digging, you will need to dig a hole that is deep enough to hold the stick in place.
The rule of thumb used by engineers who created these spikes is to dig up to ten percent of the total height of the pole. As for the width, the set should typically be about 4 times the diameter of the mast – more if you are in the soft soil or extremely windy area.
