Asphalt is only as good as what sits beneath it. We excavate, grade for drainage, and build a compacted base that holds up through Livermore's wet winters and dry summers before any pavement goes down.
Grading and excavation in Livermore means reshaping the ground so it drains correctly and sits at the right height for paving, removing unstable soil or old pavement, and installing a compacted aggregate base. Standard residential driveway grading and excavation typically takes one to two days, after which paving can follow within a day or two.
Most pavement failures in the Livermore area start below the surface - in the clay-heavy subgrade that shifts through the wet-dry seasonal cycle. Getting the ground preparation right is what separates a driveway that holds for 15 to 20 years from one that cracks and sinks within three. If your project also involves a new paved surface, drainage solutions can be designed alongside the grading to handle Livermore's winter rain volumes.
We serve property owners throughout Livermore and the wider Tri-Valley for new driveways, parking areas, ADU site prep, and regrading projects. We handle permit applications when required and coordinate utility locating before any excavation begins.
If water runs toward your foundation after a rain rather than away from it, the ground slope is working against you. In Livermore's wet winters, this means water pooling against your home's base or seeping into a garage. Regrading must happen before any new paving goes down.
Any new asphalt surface needs a properly prepared base to last. Grading and excavation are the essential first step for any new driveway, parking area, or widening project. Skipping this phase is the most common reason new pavement fails within a few years.
Visible dips, humps, or areas where water pools on your driveway are signs that the ground beneath has shifted. In Livermore, clay soil expansion and contraction through the seasons is a common cause. Patching the surface will not fix underlying movement.
Hillside and valley-edge properties in the Livermore area often have sloped lots that limit how the space can be used. Grading can level a section of yard for a patio, parking surface, or ADU pad, turning an awkward slope into functional outdoor space.
Our grading and excavation work covers the full range of residential and commercial ground preparation in Livermore and the Tri-Valley. Every job includes a site assessment, drainage planning, utility coordination, and a compacted base before any paving begins. For projects where the excavated area also needs concrete curbing and sidewalks to define edges and guide drainage, we coordinate that scope in the same project timeline.
Properties where drainage has been the chronic problem often benefit from combining grading with drainage solutions - catch basins, channel drains, or French drains - that carry water off the surface even when rainfall is heavy. We scope both sides of the project together so the finished grade and the drainage system work as a unit, not as two separate fixes.
Best for homeowners planning a new driveway or replacing an existing one - includes excavation, slope grading, and compacted aggregate base installation.
Best for adding a parking area, RV pad, or turnaround - shapes the area to drain correctly and provides a stable base for asphalt or concrete.
Best for properties where existing grading directs water toward a foundation or structure - restores correct slope without full excavation.
Best for new construction, ADU site preparation, or heavily damaged driveways where the base must be fully removed and rebuilt from the ground up.
The Livermore Valley sits on expansive clay soils that swell when wet and shrink when dry. This wet-dry cycle - Livermore gets most of its rain from November through March, then goes almost completely dry through summer - puts relentless stress on anything paved over that ground. A contractor who does not account for clay movement will grade to a minimum depth and call it done. What you get is a driveway that looks fine in year one and starts shifting by year three. We excavate to the depth your specific site requires and build the base with Livermore's soil conditions in mind. The City of Livermore also has permit requirements for driveway work that connects to public streets, and we handle that coordination so you do not have to.
We serve properties throughout Livermore and neighboring Tri-Valley communities, including Pleasanton and San Ramon, where the same clay-soil and seasonal drainage conditions apply. The California Contractors State License Board requires grading and excavation contractors to hold an active state license - something you should verify before signing any contract for this type of work.
We visit your property to look at the existing grade, soil conditions, drainage patterns, and scope of work. You receive a written estimate before any work begins - and we discuss the drainage direction plan with you on site.
Before any digging starts, underground utilities are located and marked. If a permit is required - for example, for a driveway apron connecting to a city street - we submit the application and coordinate the timeline. We reply to all estimate requests within one business day.
Our crew uses equipment to cut and remove soil, old pavement, or other material to the depth needed for a stable base. Excavated material is loaded and hauled away. Most residential excavation is completed in one day.
We grade the exposed surface to the correct slope and elevation so water runs away from your home. A compacted aggregate base is spread and packed in passes with a plate compactor. Once base inspection passes - if required - paving can begin, usually the next day.

(925) 409-3650Livermore's valley clay soils swell in winter and shrink in summer. We set grades specifically to account for that seasonal movement and direct every drop of water away from your foundation - not just to the minimum slope standard.
When a driveway connects to a city street, we apply for the required permit and coordinate the inspection timeline as part of the job. You should not have to navigate city permit offices alone - that is our responsibility.
We hold an active California state contractor's license - you can look it up on the CSLB site before you sign anything. We also carry liability and workers' compensation insurance on every job.
We coordinate underground utility locating before any excavation begins, protecting gas, water, and electrical lines on your property. This is a non-negotiable step on every grading job, regardless of project size.
Ground preparation done right is invisible once the paving goes down - but you feel it every year the surface stays flat and drains cleanly. That is what we build toward on every grading and excavation project in Livermore.

After grading and excavation set the foundation, concrete curbing defines edges and controls drainage across driveways and lots.
