Even the best asphalt fails on a bad base. We excavate unstable clay, set the right drainage slope, and compact the foundation before a single load of asphalt goes down.
Grading and excavation in Los Banos means removing unstable or soft soil to the correct depth, reshaping the ground surface so it drains away from your home, and compacting a crushed aggregate base before paving begins - a standard residential driveway project typically takes one to two days, leaving a firm, inspection-ready surface for the asphalt crew.
The quality of the work done underground determines how long your pavement lasts above it. In Los Banos and the surrounding San Joaquin Valley, the native clay soils expand when wet and shrink when dry, year after year. Pavement laid directly on unstable clay will crack and sink no matter how good the asphalt is. Proper excavation removes or stabilizes those problem layers and replaces them with a compacted base that does not move with the seasons. If you already have pavement that keeps cracking in the same spots, the base is almost certainly the reason - and the solution starts underground.
Grading is also what determines where water goes after it rains. A correctly sloped surface sends runoff away from your foundation and toward a proper drainage path. For properties with persistent pooling near the garage or along the driveway edges, regrading often solves the problem that no drainage solutions surface fix can address on its own.
Standing water on or along your driveway after even a light rain means the surface is not draining properly. In Los Banos, clay soils hold water rather than absorbing it quickly, so pooling water softens the base beneath your pavement and accelerates cracking. Regrading corrects the slope and sends water where it belongs.
Visible cracks, low spots, or sections that feel soft underfoot signal that the base beneath the pavement has shifted or settled. San Joaquin Valley clay movement from wet-dry cycles is the most common cause here. Patching the surface without addressing the underlying grade is a short-term fix - the problem will return.
If you are adding a driveway, expanding an existing one, or paving a parking area for the first time, grading and excavation are the required first step. No matter how good the asphalt is, it will only perform as well as the ground it sits on. Starting with proper site prep is the difference between pavement that lasts decades and one that fails in a few years.
If a gravel or dirt driveway has developed deep ruts, soft spots, or areas that turn to mud every winter, the ground has never been properly shaped and compacted. Excavating and regrading, then laying a proper aggregate base, transforms an unreliable surface into one that holds up year-round - a common need on rural and semi-rural parcels around Los Banos.
We handle grading and excavation for new driveway installations, parking area construction, site regrading for drainage correction, and base rebuilds on existing paved surfaces that have failed from the ground up. Every job begins with a thorough site assessment - we evaluate the existing grade, note drainage patterns, identify any underground utilities that need to be located before digging, and check soil conditions across the work area. In California, utility marking is required by law before any digging begins, and we build that step into every project schedule. Underground Service Alert (811) coordinates those markings at no cost to you.
Grading and excavation is the first phase of any new paving project. Once the base is properly prepared and inspected, we coordinate directly with our paving crew for concrete curbing and sidewalks, asphalt installation, and any other surface work on the same project. For drainage-specific slope corrections, we also coordinate drainage solutions so the finished grade and subsurface drainage work together. You get one point of contact for the full project, not separate contractors who have to coordinate on their own.
Best for homeowners building a new driveway or expanding an existing one who want a properly prepared base before asphalt is installed.
For properties where water pools near the foundation or driveway edges - correcting the slope sends runoff to the right place.
Suited to driveways and parking areas where cracking or sinking keeps recurring because the original base was never properly prepared.
The San Joaquin Valley floor under Los Banos is composed largely of expansive clay soils - soils that swell when they absorb winter moisture and shrink back as the ground dries through the long, hot summer. This wet-dry cycle repeats every year and applies steady upward and lateral pressure against any pavement sitting above it. Proper excavation removes or stabilizes the most problematic clay layers and replaces them with a compacted aggregate base that does not shift with the seasons. Skipping or shortcutting this step is the single most common reason driveways and parking areas in this area fail early. Many properties in and around Los Banos are also larger rural or semi-rural parcels with long driveways or unpaved access roads that have never been formally graded - and those surfaces show every inch of the clay-soil problem.
Spring and fall are the best windows for grading work in this area. Spring soil retains enough moisture to be workable, and getting the base ready before summer heat sets in means paving can follow in ideal conditions. Fall grading before the rainy season means the finished pavement has the best possible base going into winter. We regularly work on properties throughout the broader area, including customers in Dos Palos and Gustine, where the same clay-soil conditions and flat valley-floor drainage challenges apply.
We reply within one business day. You describe the area and what you are trying to accomplish - a new driveway, drainage correction, or full site prep. We schedule a free on-site visit to assess the soil and grade conditions before giving you a written estimate.
During the visit, we evaluate the existing grade, drainage patterns, and soil conditions. We also arrange for underground utilities to be marked before any digging begins - required by California law and typically takes a few business days of lead time.
The crew arrives with the right equipment for your site - excavator, skid steer, or motor grader depending on the scope. We remove existing material, shape the ground to the correct elevation and slope, install and compact a crushed aggregate base. A standard residential driveway project takes one to two days.
If a permit was required, an inspection happens before paving begins. Once the base passes - or if no inspection is required - the site is ready for the asphalt crew. We walk you through what was done and confirm the drainage slope before we leave.

(209) 592-1268Working in the San Joaquin Valley for years has given us first-hand experience with the expansive clay soils that underlie most Los Banos properties. We do not apply a standard suburban formula - we assess the actual soil conditions on your site and excavate to the depth and specification those conditions require.
California law requires underground utilities to be marked before any digging begins. We handle the 811 call-before-you-dig process as a standard part of every job - protecting your irrigation lines, gas service, and other buried infrastructure from the start. No shortcuts that cause delays or damage.
A compacted base that is not properly verified before asphalt goes down is a problem waiting to happen. We check for soft spots across the entire prepared area and address them before the paving crew arrives. If a permit inspection is required, we coordinate it so there are no delays in your project timeline.
California requires a state contractor's license for grading and paving work. You can look up our license status on the California Contractors State License Board website (cslb.ca.gov) before we start. A current license means we carry the bonding and insurance that protect you, and that our work meets California's standards for this type of project.
Grading and excavation is the most consequential phase of any paving project - get it right and everything that follows performs well for years. Get it wrong and no amount of quality asphalt on top will fix what is happening beneath it. We take this phase seriously because our customers' satisfaction depends on it.
Once the grade is set and the base is compacted, concrete curbing and sidewalks give the finished project clean, defined edges that hold the pavement in place.
