Benchmark Excavation: Professional Fence Builders Serving Evergreen, MT 59901

Freeze-thaw cycles and poor soil drainage are the main culprits. When the ground under a post freezes and thaws repeatedly, it can push the post upward or sideways. Benchmark Excavation solves this by regrading the area for better drainage, excavating to stable soil, backfilling with compacted material, and setting posts below the frost line. This keeps gates aligned and fences straight year-round.

Yes, it often means the gate posts or foundation have shifted due to frost heave or erosion. Even a small tilt can throw off the gate's alignment, causing the motor to struggle. Benchmark can inspect the site, re-excavate and compact the soil, then reinstall the gate on a stable concrete footing. They also check the drainage to prevent future movement.

Instead of simply following the slope, which can cause gaps under the fence, Benchmark Excavation uses land grading and earthmoving to create stepped terraces or a gentle, uniform grade. They can also trench for post holes deeper on the downhill side to ensure consistent height and no sagging. This keeps the fence looking professional and secure.
