If you want to install a chain link fence, you should know that it is very important to dig a suitable post hole, the depth of the post holes is the most important factor in the stability of your targeted fence. Another important factor to consider when digging post holes is knowing where cable lines and gas lines are located. These lines are typically run underground, and they can easily be cut with a shovel or an auger. The following paragraphs will give you some information that will help dig a fence post hole rightly.

Tools: shovel or auger (a drill like machine that is more easily capable of digging out post holes in hard ground)

To avoid interrupting services or potentially putting yourself in danger, before digging the fence post holes, you need to call the cable company and gas company. The cable and gas companies will come to your home and mark exactly where the lines are located with flags and spray paint.

Concrete
Your concrete should be a gravel mix. It can be purchased at the same place you purchase your chain link fence posts. Concrete for fence posts typically comes in 40 and 60 pound bags. For fence post holes that are 2 feet deep use at least one 40 pound bag of concrete. For post holes that are 32 inches deep to 36 inches deep, use a 60 pound bag of concrete.

Width
The width of your fence post holes should be at least10 inches wide. This width will allow adequate room for concrete to be poured into the holes. Not all installers use concrete to set the posts. Concrete provides the most strength for your chainlink fence posts. There are some fence installers will refill the holes using the dirt that was removed from digging, and with rock. This procedure does make it easier to replace a post if it should happen to break or split.

Depth
The depth that you should consider digging the fence post holes is between 2 and 3 feet deep. The deeper you dig the holes, the more stability your fence has, so you'd better purchase some longer posts. Moreover, you also need to trim off 1 foot in length to accommodate the height of the chain link fence panels. The minimum depth for your gate posts is considered to be 32 inches. The reason for this depth is that the posts must be able to handle the weight and the movement of the gate.
