The traditional method of setting chain link fence posts is to “set” in concrete. When using this process, it is very important to dig post holes below the frost line (usually 24-36” depending on the area) and to bell out the bottom of the hole. Even with this strategy, the frost can eventually push the concrete footing out of the ground. This is also known as frost heave. One solution to this issue can be driving the posts! All farm fencing including t-post and wire, half round rail, and deer fencing have always been driven in Montana. We have installed this style of fencing for the homeowner and rancher along with the Montana Department of Transportation on hundreds of miles of highway fencing. We noticed that none of these fences had frost heave issues. When we began fencing in North Dakota for the Bakken oil boom, we discovered that most North Dakota fence contractors pounded their chain link fence posts. We followed their lead and began pounding chain link posts. We were amazed at the strength and integrity of the product as well as the lack of frost heave. Because of this, we’ve added this method to our repertoire for jobs with dirt, clay, and semi-rocky soil. Some major pluses include:
1. No dirt to clean up
2. Fewer damaged sprinkler lines
3. Elimination of frost heave
4. Faster Fence Installation – no wait time on concrete curing
5. Lower cost without compromising product integrity
Sometimes concrete can still be the better option. In areas with loose soil, concrete is the most secure method of installation. It totally depends on the soil/ground quality to decide which method is best for your project.
