Underground Utility Construction

The core of what we do: opening the ground and putting electric, communications, gas, and water where they belong, below grade and to spec.

What it is

Trench it, bed it, bury it, mark it

Most utility runs still go in the ground the old, reliable way: an open trench, cut to the right depth, with conduit or direct-buried cable laid on clean bedding and backfilled in lifts. Pro-Tech does that work with the separation, the tracer wire, and the warning tape the utility requires, so it passes inspection and the next crew knows what is down there.

  • Open-cut trenching to required cover depth
  • Direct-bury of primary, secondary, and comm cable
  • PVC conduit and concrete-encased duct banks
  • Tracer wire and color-coded warning tape on every run
  • Bedding, select backfill, and compaction in lifts
  • Manholes, handholes, and pull boxes set to grade

Depths and materials follow the serving utility's construction standard. We build to that standard and record the as-built depths for the owner.

Cable & Fiber

Once the duct is in, we pull and terminate the cable and fiber.

Directional Boring

Where a trench cannot go, we bore under it instead.

We verify existing lines first and put the ground back after.
