Serving Lodi, CA and surrounding areas. (209) 280-3669
Every lasting driveway starts below the surface. We grade and excavate to create a stable, properly drained base before any asphalt goes down - the step that determines whether your paving holds up for years or fails by season three.
Grading and excavation in Lodi means shaping the ground to the right level and slope, removing unstable material, and compacting a solid aggregate base before any asphalt is placed - most residential driveway jobs take one to three days from start to finish. On the San Joaquin Valley clay soils around Lodi, this step is not optional: asphalt laid over soft, poorly drained ground will crack and sink within a few years regardless of how well the surface was paved. The grade also determines where your water goes. Lodi's relatively flat terrain means drainage has to be engineered deliberately - water needs a clear path away from your home and off your driveway, not just somewhere to pool. If your project involves addressing existing water problems alongside the grading work, pairing it with drainage solutions ensures the whole system is handled together.
Standing water collecting near your foundation or along your driveway after a winter storm means the ground is not draining correctly. On Lodi's flat terrain, this kind of pooling happens quickly during the wet season and is a clear sign the grade needs to be corrected before any paving begins.
Dips, humps, or areas where the existing surface has settled unevenly point to a base that was never properly prepared or has shifted over time. Paving over these spots without regrading first buries the problem and the new surface will follow the same pattern.
Any new asphalt installation starts with grading and excavation - there is no shortcut. Whether you are adding a driveway, expanding a parking area, or paving a side yard, this groundwork has to happen first. Skipping it shortens the life of the new surface significantly.
If patched cracks keep coming back in the same locations, the problem is likely underneath - unstable or poorly graded soil that keeps moving. Repeated cracking in the same area is a sign that surface repairs alone cannot fix the underlying issue.
We handle grading and excavation for new driveway installations, driveway replacements, parking area expansions, and yard regrading projects across the Lodi area. Every project starts with a site assessment that covers the existing grade, soil conditions, drainage patterns, and underground utility locations. In California, we call 811 before any digging begins - this is required by law, and it is something we do as a matter of course on every job, not just when we remember to. For new driveway projects, our scope includes excavating to the required depth, removing unsuitable material, shaping the grade to move water away from the home and toward the street or a designated drainage point, and compacting a layer of aggregate base before paving begins. The drainage slope is checked twice - after rough grading and again after the base is placed - before any asphalt goes down.
For properties with existing drainage problems or lots where cracks and surface failures keep returning, we pair grading work with a full assessment of whether concrete curbing and sidewalks or dedicated drainage infrastructure would address the root cause. Grading that directs water toward a curb or drainage structure lasts far longer than grading that just creates a slope with nowhere for water to go at the end. We explain the drainage plan clearly before work begins so you know exactly where the water will go after we are done.
Best for homeowners planning a new asphalt driveway who need the ground properly shaped and a compacted aggregate base installed before paving begins.
Best for existing driveways being torn out and replaced - old material is removed, the grade is corrected, and a new base is built before new asphalt is laid.
Best for properties where water pools near the home or in low spots across the yard, requiring the grade to be reshaped to direct runoff away from the foundation.
Lodi sits on the San Joaquin Valley floor, where the soils are clay-heavy and slow to drain. Clay expands when the winter rains arrive and shrinks back in the dry summer heat - a cycle that repeats every year and stresses anything built on top of it. Grading work that accounts for this behavior looks different from grading on sandy or loam soils: the excavation typically needs to go deeper to reach stable ground, the compaction has to be done in lifts, and the drainage slope has to be intentional because the flat terrain does not give water a natural path. Older Lodi properties - especially those on the agricultural fringes of town or on larger lots near the city center - may also have buried irrigation lines, drainage tiles, or field infrastructure that pre-dates modern utility mapping. We serve homeowners and property managers throughout the area, including Tracy and Lathrop, and local experience with the valley's soil and drainage patterns is what separates a grade that holds from one that settles and fails within a few seasons.
The wet-dry cycle also dictates the best timing for this work. Grading and excavation done during the dry season - late spring through early fall - gives the prepared base time to settle and compact naturally before the November rains arrive. Scheduling in this window means your new driveway or regraded surface is ready and fully tested by the first storm of winter. Projects scheduled too close to the rainy season risk having the freshly prepared base disturbed by rain before paving can begin, which adds time and cost. We will talk through timing honestly during the estimate so you can plan around the calendar, not against it.
Call or submit the form and we will respond within 1 business day. Tell us what you are planning - a new driveway, a regrading job, or a drainage fix - and we will schedule a free on-site visit to assess the area in person before giving you a quote.
During the site visit, we evaluate the existing grade, soil conditions, and drainage patterns. We identify any underground utilities that need to be marked before digging - in California this is done through the 811 call-before-you-dig service, which is required before any excavation.
If the project involves work near a city street connection or affects public drainage, we handle any required permit or encroachment approval on your behalf. Once approvals are in place, the crew arrives with equipment and begins shaping the grade, removing unsuitable soil, and hauling material away.
After the ground is shaped, a layer of compacted aggregate base is spread and rolled to the correct slope. We walk the site with you before paving starts so you can see the drainage slope and confirm everything looks right - this is your chance to flag anything before the asphalt goes down.
We respond within 1 business day. The site assessment and estimate are free. After you submit, someone from our team will call to walk through the scope and set up a time to visit your property.
We call 811 before any digging starts - it is required by California law and it is something we do without exception on every project. The call811.com service marks underground utilities before excavation begins, protecting your property and your neighbors. Lodi has many older lots with agricultural irrigation lines that do not appear on standard maps - we treat every dig as if something unknown is buried.
Lodi's flat terrain does not drain itself - water needs a deliberate slope to move off your driveway and away from your foundation. We design the grade with a clear drainage destination built in, not just a surface that looks level. Correct drainage at the grading stage is what protects your asphalt investment through the wet-dry cycle year after year.
We have been working on the San Joaquin Valley clay soils around Lodi since 2020 and know how to excavate and compact in a material that behaves very differently from the sandy or loam soils used in most general grading guides. Proper lift compaction and stable sub-grade preparation are what make the difference on expansive clay.
If your project requires a grading permit or encroachment approval from the city of Lodi or San Joaquin County, we handle the paperwork on your behalf. You should not have to navigate permit processes on your own - we know which jobs trigger requirements and we manage that step as part of the job.
The best time to get grading right is before the asphalt goes down - not after the first season of settling. Every project we complete is built on the same principle: a grade that drains, a base that is compacted properly, and a surface that holds up through what the Central Valley delivers every year.
Add defined edges and pedestrian surfaces after grading is complete so your driveway or lot has clean borders that hold the base material in place.
