NA Fencing & More Services: Local Fence Contractors Serving Midland, TX 79705

The primary cause is our local soil's high clay content. When it rains, the clay soil expands, putting pressure on the fence posts. During dry spells, the soil shrinks and pulls away from the post. This constant cycle of expansion and contraction loosens the soil around the post, leading to instability. Over time, this movement can also cause the post to erode at the ground level, especially if it's untreated wood.

Look for obvious signs like a fence that is leaning to one side or gates that no longer latch properly. You might also notice visible gaps between the fence post and the ground, or small mounds of displaced soil around the base of the post. If you push on the fence and it wobbles, or if you see cracks in the concrete around the post base, these are strong indicators of soil movement or post erosion.

The most effective solution is to install new posts with a deep-set concrete foundation. We dig holes well below the frost line and the active soil zone—typically to a depth of 24 to 30 inches. We then use a gravel base for drainage and pour a concrete collar that extends above the soil line. This method locks the post into stable soil below the shifting clay layer, preventing future movement and erosion.
