When it comes to setting chain link fence posts, the traditional method involves “setting” them in concrete. This process requires digging post holes below the frost line, usually 24-36 inches, and belling out the bottom of the hole. However, frost can still push the concrete footing out of the ground, also known as frost heave. To avoid this issue, one solution is to drive the posts. In Montana, farm fencing, including t-post and wire, half round rail, and deer fencing, has always been driven, and fences installed using this method have not had frost heave issues.
When we began fencing in North Dakota for the Bakken oil boom, we noticed that most North Dakota fence contractors pounded their chain link fence posts. Following their lead, we started pounding chain link posts and were amazed at the strength and integrity of the product, as well as the lack of frost heave. Consequently, we’ve added this method to our repertoire for jobs with dirt, clay, and semi-rocky soil. Some benefits of this method include no dirt to clean up, fewer damaged sprinkler lines, elimination of frost heave, faster fence installation without wait time on concrete curing, and lower cost without compromising product integrity.
However, in areas with loose soil, concrete may still be the most secure method of installation. It depends on the soil/ground quality to decide which method is best for your project.
