New asphalt is only as good as what is beneath it. We excavate, grade, and compact so your driveway handles Bay Area clay soils and drains the way it should.
Grading and excavation in San Leandro, CA reshapes the ground beneath driveways and paved areas to the correct slope and depth, removes unstable or excess material, and compacts the base so water drains away from your home and new asphalt has a stable foundation - typical residential driveway projects take one to two days from start to finish.
If your driveway is cracking and sinking, or if you are starting fresh with a new surface, what happens below grade is what determines whether your pavement lasts five years or twenty. San Leandro sits on clay-heavy soils that expand in the wet season and shrink back in summer. That seasonal movement stresses pavement from below, opening cracks and accelerating settling - especially on older driveways that were never properly excavated to begin with. Grading done right accounts for that soil behavior from the start. When a project also calls for managing where surface water goes, we pair grading work with our drainage solutions service to make sure water has somewhere to go once the grade is set.
Skipping or rushing grading is the most common reason driveways fail early. A surface that looks fine on day one but sits on a poorly prepared base will crack and settle within a few years - and the repair at that point is far more involved than doing it right the first time.
Cracks that run in a pattern, or sections of your driveway that have dropped lower than others, mean the ground underneath has shifted or settled. In San Leandro's clay-heavy soils, this movement is common and gets worse over time if the base is not corrected. Patching the surface without fixing the grade underneath is a short-term fix that will not last.
Standing water collecting near your home after a rainstorm means the ground is not draining the way it should. This is a grading problem, not just a drainage problem, and it can lead to water intrusion and foundation damage over time. Regrading the area to direct water away from the structure is the right fix.
Any new asphalt installation starts with proper grading and excavation. If you are replacing an old driveway or adding a new one, the ground needs to be prepared correctly before any pavement goes down. Skipping this step - or hiring someone who does - is the most common reason new driveways fail within a few years.
Uneven pavement is a trip hazard and a sign that the soil beneath has moved. In the East Bay, seasonal clay expansion and contraction is a common culprit. Regrading and repaving restores a safe, even surface and addresses the root cause rather than just patching the top.
We handle driveway excavation and regrade projects, foundation drainage corrections, and site preparation for new paved surfaces and structures throughout the East Bay. Every job starts with a site visit where we assess the slope, soil conditions, equipment access, and drainage requirements before we give you a price. Work begins only after underground utility lines are marked through the state notification system. Crews use compact excavators and skid-steer loaders for residential sites, shaped to fit tight lots common in San Leandro's mid-century neighborhoods. When the project connects to a new asphalt surface, we coordinate directly with our paving crews so the transition from site prep to finished pavement is seamless. Projects that require shaping concrete edges or curbing around a regraded area can be combined with our concrete curbing and sidewalks service so the entire perimeter is handled in one project.
For sites where stormwater management is a primary concern, we work alongside our drainage solutions team to design the grade and drainage outlet together. In the Bay Area, where regional stormwater rules affect how runoff is managed on paved sites, having grading and drainage designed as a single system - rather than two separate jobs - produces a better outcome and simplifies the permit process.
For homeowners replacing an old driveway or fixing one that has cracked and settled - we excavate to the right depth, correct the grade, and prepare the site for new asphalt.
Suited to properties where water is pooling near the garage or foundation after rain - we regrade to direct runoff away from the structure and toward a proper outlet.
Ideal for homeowners adding a garage, carport, or any structure that needs a properly prepared, level, and compacted base before construction begins.
San Leandro's Mediterranean climate concentrates nearly all rainfall between November and April. Freshly graded soil that gets saturated before paving can shift, erode, or become unstable - which is why scheduling grading and excavation in the dry months, late spring through early fall, matters here more than in drier regions. The clay-heavy soils across the East Bay flatlands compound the challenge. Clay expands with every wet season and contracts through the dry summer, so a base that was not excavated deep enough and compacted properly will keep moving long after the asphalt goes down. Many of San Leandro's driveways from the 1950s and 1960s were never built with this soil behavior in mind, and it shows in the cracking and settling homeowners deal with today.
The San Francisco Bay Area also has regional stormwater management requirements that affect how grading work is designed and permitted. Runoff from paved surfaces must be managed so it does not carry pollutants into the Bay, and depending on the size of your project, your contractor may need to address drainage as part of the permit review. We work on properties across San Leandro, from the flat streets near Hayward where drainage toward the storm system is straightforward, to the hillside lots near Oakland where steep grades and retaining walls add complexity to every grading job.
We visit your property to assess the slope, soil conditions, equipment access, and whether any material needs to be hauled away. You receive a written estimate with a clear scope of work before anything is scheduled.
For grading above a certain scale or any work touching the public right-of-way, a city permit is required. We handle the application and city coordination - this step can add several days to the timeline, so it is worth discussing early.
We remove existing material, shape the ground to the correct slope, and verify water will drain away from your home. Underground utility lines are marked through the state notification system before any digging begins.
Crushed aggregate base is spread and compacted over the graded soil. If a permit was pulled, a city inspector may sign off before paving begins. We walk you through the finished grade and confirm the site is ready for the next phase.
We visit your property, assess the slope and soil conditions, and give you a clear written quote - no pressure, no surprises.
Grading and excavation work in California requires a valid state contractor's license. Ours is active and searchable online. Ask any contractor you speak with for their license number and verify it - it takes 30 seconds and protects you from unqualified operators.
San Leandro sits on expansive clay soils that swell every wet season and shrink every summer. We excavate to the depth and specification that accounts for this movement - not the minimum that looks fine on day one but fails within two years.
San Leandro requires permits for grading above certain thresholds, and work touching the public street apron involves a separate city approval. We know which projects trigger what requirements and handle the process so you do not have to track it down yourself.
We explain the planned drainage slope before we start and walk you through it when the work is done. The San Francisco Bay Area's stormwater management requirements - outlined by the regional water quality control board - make proper drainage design a real compliance issue, not just a preference.
Good grading work is invisible when it is done right - you just notice that the pavement holds, the water drains, and you are not calling for repairs every other year. That is what we aim for on every job in San Leandro.
To verify a contractor's license before signing, use the California Contractors State License Board. Stormwater management requirements for grading projects in the Bay Area are administered by the California State Water Resources Control Board.
After grading is complete, concrete curbing defines the edges of paved areas and gives the finished surface a clean, lasting border.
