A Modern approach to excavation

At BoltWest, we lead with innovation, safety, and precision — specializing in hydro-excavation services that protect what matters most. Because when it comes to underground work, cutting corners is never an option. With our best in class trucks, we maximize efficiency by utilizing the strongest blower, biggest hose to move material fast without clogs or hang ups that reduce productivity. Our trucks can get set to safe psi values to avoid damage to existing facilities and maximize efficiencies. We have a boiler system that enables us to heat water in tough digging conditions like clay and frozen ground. Cutting through the toughest material and wasted time on your project.

What sets us apart

At BoltWest, we believe the future of excavation is all about safeguarding people, infrastructure, and the environment.

With firsthand experience in the risks of second-guessing what’s underground, we knew there had to be a better way.

That's why we lead with innovation, safety, and precision — specializing in hydro excavation services that protect what matters most.

With BoltWest being one of the only hydrovac companies located in Marin County. With dumping sites in Marin and SF, we make it easy for multiple trip loads in one shift.

Potholing/Daylighting

We can provide or delineate a running line. Saw cut and breaking when available. Ask about our rates. We also record and photograph all potholes by utilizing type, depth, and size. Backfill potholes or plate as needed. Ask about our rates and services for more info!

Dry Excavating


Whether it’s sand or gravel, BoltWest can excavate with no water. This enables the reuse of material and the ease of transport to the stage location onsite or to another location.

No mess, no water, just less labor costs and more money in your pocket.

Trenching

Fast, efficient, safe, and least impactful on the surrounding environment, making clean up and restoration minimal. Remote hose available. Helps prevent damage to mature vegetation and trees, reducing damage to roots. Can be used in areas where there are abundant utilities that traditional earth equipment can’t be used in. Preventing dig-ins and costly damage outages.

POLE HOLE DIGGING

We can pre-dig pole holes and anchor holes ahead of crews to keep projects moving.

Shoring Options: Culverts and sonotubes available when needed.

Backfill: Available same day or staged in advance. We can supply bagged ¾” rock or cutback for quick, compliant backfill.

ENCLOSURE CLEAN OUTS

Clean outs available for non-hazardous underground encloses all shapes and sizes. BoltWest can provide QEW if needed.

Same Day Mobilization with Emergency Response

Same day mobilization is dependent on availability. Being classified as a soft method, we’re able to start digging as quickly as you need. Proud to support emergency tag work and storm work. Any time, any place, and anywhere, feel free to inquire about your needs.

Extreme Temperature

While the Bay Area doesn’t often see extreme temperatures, our units are equipped for performance in tougher conditions. Our heated water capability allows us to tackle:

-Hard compacted soils

-Clay heavy conditions

-Cold weather excavations

-Challenging utility exposures

When conditions get tough, BoltWest stays lightning fast.

Remote Hose Jobs

For backyards to remote pole holes, BoltWest offers up to 200ft max of remote hose from the truck. This is billed in 25ft sections at $7/ft.

Why Choose Hydro-Excavation?

  • Hydrovac excavation is up to 10x faster and safer than hand-digging for potholing, reducing labor costs and utility strike risks.

  • The U.S. experiences 400,000 to 800,000 utility strikes annually, costing an average of $4,000 per incident in damage alone.

  • Traditional, non-vacuum excavation causes roughly 1,000 injuries and 75 deaths annually due to trench cave-ins.

  • High-pressure water and vacuum systems allow for faster, more precise excavation, such as locating a 6-inch pipe in 5 minutes.

  • Hydro Excavations results in less soil disruption and cleaner, more targeted excavation compared to conventional methods.
