Clean, Accurate Trenches for Every Underground Line

Utility trenching is the precise digging of trenches that carry water, sewer, electric, and other underground lines — and it is a core part of what Beeman Excavating does every week. Done right, trenching is straight, properly graded, and dug to the exact depth each utility requires. Commercial builders and contractors across the DeKalb area and northern Illinois count on us to trench it clean and trench it safe.

What It Is

Trenching is the controlled excavation of narrow channels for underground utilities. Each line — water, sewer, storm, gas, electric, communications — has its own depth, bedding, and separation requirements. Good trenching meets those specs exactly so the utilities install cleanly and pass inspection.

Frequently Asked Questions

How deep do utility trenches need to be?

Depth depends on the utility and local code — water and sewer lines sit below the frost line, while other lines have their own requirements. We trench each to the depth it needs.

Do you locate existing utilities before trenching?

Always. We mark existing lines and plan the route before digging, which protects the crew and prevents costly strikes on lines already in the ground.

Can you trench around existing underground lines?

Yes. We work carefully around marked utilities, adjusting our approach and equipment so we install new lines without disturbing what is already there.

Do you backfill and compact the trench when you're done?

We do. Proper bedding, backfill, and compaction are part of the job, so the trench does not settle and the surface above stays stable.
