Do you compact to a specified percentage?

Yes. Backfill goes in and gets compacted to the percentage a soils engineer specifies, in lifts, whether the material is native soil or imported baserock and sand. If your project has a soils report with a number in it, that number is what we work to. If it does not, we will tell you on the walkthrough whether it should.

Can you import and export material?

Both, in any quantity. We have the trucks, so baserock, sand or fill comes in and spoil goes out on the same mobilization instead of waiting on a hauling subcontractor. That also means a pile of dirt you need gone is a phone call, not a project.

How do you hit the elevation on a grading job?

With lasers and the plan, not by eye. Whether it is a backyard that needs a specific slope for drainage or a jobsite that has to come to a set elevation before the build starts, we grade to the number. Our fleet handles anything from a single backyard to a full site.

What We Dig

One fleet, no subcontracted hauling.

Foundation excavation

Site cleared if it needs clearing, then earthmoving to plan. Any size.

Utility trenching

Through concrete, pavers or hardpan, out to a new ADU, shed or garage. Dug and backfilled by the same crew.

Pier drilling

Deep piers for unstable ground, drilled up to 30 feet with our own rig and augers.

Grading

Graded to plan with lasers, to the exact elevation or slope called for.

Backfill & compaction

Native soil or imported baserock and sand, compacted to the percentage the soils engineer specifies.

Dirt removal & hauling

A pile of fill dirt you cannot get rid of, gone. We pick up whatever you have excavated.

Bobcat services

The entire SF Bay Area, the Peninsula and the South Bay. Trenching, drilling and breaking out concrete.

Trenching

Every trench exists for a reason. The reason sets the depth.

French drains. The trench the drainage system needs before it can be installed, cut to fall.
Sewer lines. Sewage has to move across the property, and the line has to stay reachable for maintenance later. Every utility gets buried accordingly, with provision for environmental protection.
Gas and HVAC piping. Natural gas and propane lines run under homes and commercial properties. Those trenches exist to protect the pipe from environmental damage and keep the gas moving efficiently underground.
Retaining walls and footings. Footing trenches for retaining walls and foundations, dug to the structural plan rather than to a guess.
Power and utility runs. Circuits upgraded, or service taken out to a new ADU, shed or garage. Dug and backfilled by the same crew.

Common Questions

What contractors and owners ask first.

Up to 30 feet. Deep piers are what structural plans call for when the ground is unstable, and they need specialized augers, drill bits and machinery to do properly. We own the rig and the drilling accessories rather than renting them by the day, which is why pier work does not sit waiting on someone else’s equipment schedule.

Send the plan. Get a written number.

We check access for the machines, what is under the ground and what the plan demands, then put an itemized price in writing. No charge, no obligation.
