Underground

Maggiora & Ghilotti’s experience in underground utility installation runs deeply.  Not only does our utility experience date back to 1964, but also our experience in depths of up to 36 feet in bay mud shoring gives us superior experience over other utility contractors.  We are familiar with the hydraulics of bay mud and the know-how to safely penetrate it.

We are experienced in all categories of utilities:

  • Waterlines
  • Sanitary Sewers
  • Storm Drains
  • Gas Lines
  • Electrical Conduits
  • Joint Trenches

For precision installation we use the latest in laser alignment equipment. Our numerous utility crews can be seen regularly on city streets. Maggiora & Ghilotti has placed the largest diameter pipeline (12' dia) in the county under Highway 101 for a flood control project.

Here's what our customers say:

“If its deep, tough or in traffic we hope Maggiora & Ghilotti is the low bidder.”
