How to Set Poles for a Pole Barn
Although pole barn poles are treated to resist rot and weather damage, they must be set in the ground with extra care because the soil has pests and chemicals that will erode any wood quickly. Caring for the material is just one of many parts involved in setting these poles. Over the years, farmers have perfected the methods for setting poles in the ground. Consequently, you can complete this type of project with great success in one or two days, depending on the size and scope of the project.

1
Measure and mark off the hole placements for the pole barn. Begin by locating one corner pole placement, and then pull a tape measure off of this mark along a straight line, marking every six to eight feet. Once you reach the opposite corner on the same wall, turn the corner and mark the same distances between the posts. Square the corners using a carpenter's square and line.

Dig the pole holes using hole diggers. Make the holes 16 inches in diameter and 48 inches deep. It is important that the poles be set at this depth. Anything less and the building may not remain sturdy. Remove all dirt from the holes.

Coat the poles with tar 48 inches up from the bottom of the pole. This will protect the post from insects and will prevent water damage to the posts. Slide all posts into the holes that you have dug and plumb the four corner posts using a four-foot hand level. Fill 12 inches of dirt into the hole and pack the soil with the handle of the hole diggers. Check the posts again so that it remains plumb, and then fill in the rest. Once all 4 corners are set, pull a nylon string from each corner, basically making a square. Align the remaining posts to the string and fill in the post holes with dirt, packing as you go. You will still need to plumb the posts, but the string will give you a good reference line.
