No amount of asphalt fixes a poorly prepared base. We excavate, grade, and compact your subgrade so new pavement has something solid to rest on - and drains away from your home the way it should.
Grading and excavation in Porterville reshapes and stabilizes the ground before paving begins - removing soft or organic material, setting the correct slope for drainage, and compacting a crushed aggregate base that gives asphalt a firm, lasting platform - most residential jobs take one to two days depending on site conditions.
A beautifully paved surface laid on poorly prepared ground will crack, sink, and shift within a few years. The grading work is what prevents low spots that hold water, slopes that direct runoff toward your garage, and base layers that compress under vehicle load.
If your driveway has already sunk, tilted, or developed depressions that hold water, the problem is almost always in the base - not the surface. That situation calls for a full excavation and regrade before any new pavement goes down. Once the base is right, we can pair the job with drainage solutions that keep water moving away from your structure long term.
Every dry Porterville summer a dirt or gravel driveway kicks up dust with every car that passes. Every wet winter it turns to ruts and mud. Proper grading and a paved surface end that cycle for good.
Standing water collecting near your home after winter rain means the ground around your driveway is not sloped correctly. Regrading to direct water away from your structure protects your foundation and eliminates a recurring wet-season problem.
Sections that have dropped, tilted, or created depressions that hold water almost always point to a base failure, not a surface problem. Patching the top will not fix a failed subgrade - it needs to be excavated and rebuilt from the ground up.
Any new driveway, RV pad, or parking area needs proper excavation and grading before asphalt goes down. Getting the ground prep right the first time means the surface lasts - doing it as an afterthought means paying twice.
We handle grading and excavation for new driveways, parking areas, RV and boat pads, and full site preparation for residential and commercial paving projects across Porterville and Tulare County. Every job starts with an on-site assessment of your soil conditions, existing slope, and drainage - because the ground in this part of the Valley behaves differently from flat, sandy soil, and the base needs to be built for it. We also coordinate with property owners on any permit requirements before work begins, so there are no delays once we start.
After grading is complete, we can pair the work with full asphalt paving or with concrete curbing and sidewalks that define the edge of your driveway and keep the base material contained. For sites with significant slope or drainage issues, we also offer integrated drainage solutions that route water off the finished surface and away from your home's foundation.
Full excavation, subgrade shaping, and compacted aggregate base for homeowners installing a new asphalt driveway from scratch.
Targeted regrading to fix low spots and redirect water away from garage slabs and foundations - the right fix for chronic pooling after rain.
Site excavation and base compaction for added parking areas, RV pads, or boat storage - built to handle heavier vehicle loads from the start.
For driveways that have sunk, cracked, or shifted due to base failure, we excavate the failed layer, regrade, and rebuild so new pavement has a stable foundation.
Porterville sits at the edge of the Sierra Nevada foothills in the southern San Joaquin Valley, where soils often carry a significant amount of clay. Clay soil swells when it absorbs winter moisture and shrinks in the dry summer heat - and that repeated movement is the primary reason driveways crack, sink, and shift in this area. A grading crew that has worked in Porterville understands how deep to excavate to get below the most active clay layer and how thick to build the aggregate base to buffer against that movement year after year. Rushing these steps produces a surface that looks good on day one and fails by year three.
Homes on the eastern side of Porterville and out toward Springville often sit on sloped lots near the foothills, where more material needs to be moved and drainage calculations matter more. Properties further west near Terra Bella tend to be flatter but face slower drainage in wet years. We assess both situations differently, because the same grading approach does not work equally well across the entire Tulare County service area.
We visit your property, measure the area, assess soil conditions and existing slope, and note how much material needs to be moved. You receive a written quote before any work is agreed upon. We reply to all inquiries within 1 business day.
If your project touches the public right-of-way - such as a new driveway apron connecting to the street - we handle the permit application. This typically adds a week or two before work begins. For purely private-property work, we confirm requirements and manage the paperwork.
The crew uses excavators and grading equipment to remove existing material, cut down high spots, and shape the ground to the correct slope and depth. Soft or unstable soil is removed and replaced with compacted fill. This is the most active phase - plan for at least a full day of equipment work.
Once the subgrade is shaped, a crushed aggregate base is spread and compacted in lifts. Before paving begins, we walk the site with you to confirm slope and drainage look right. Any concerns are far easier to address at this stage than after asphalt is laid.

(559) 854-8049We have graded sites across Porterville and the southern San Joaquin Valley and know how the region's expansive clay behaves through wet and dry seasons. That knowledge determines how deep we excavate and how thick we build the base - not a formula from somewhere else.
You receive a detailed written quote that covers scope, timeline, and total cost before we schedule anything. It specifies what is being excavated, how deep, and whether haul-away is included - so you can compare it clearly against any other bid.
California requires a valid state contractor license for grading and paving work. You can look up any contractor license at the California Contractors State License Board in seconds - it tells you the business is legitimate and legally authorized to work on your property.
Good grading produces a surface that sheds water cleanly. We factor in where water naturally flows on your property and design the slope to keep it moving away from your home and foundation - not pooling on the finished surface.
A properly graded and compacted base is what separates a driveway that lasts decades from one that needs repair every few years. Getting it right at the ground level is the most cost-effective decision you can make for any paving project.
After grading is complete, concrete curbing defines the driveway edge and keeps the base material contained where it belongs.
