Site prep, dirt work, and grading done to the plan. We strip, cut, fill, and compact your lot to a build-ready subgrade across Bentonville and Benton County.
A plain-language look at fill, aggregate, and the excavation choices behind a solid site.

The word “dirt” hides a lot of important differences. On a real excavation job the material you place matters as much as the machine that moves it, and putting the wrong stuff in the wrong spot is one of the most expensive mistakes a Bentonville site can make. Here is a plain-language walk through the material choices behind a solid lot.
Fill dirt fills a void. It is fine for raising a low spot in the yard, backfilling a landscape area, or bringing a rough grade up. What it will not do is carry a load. Structural fill is engineered material placed in controlled lifts and compacted to about ninety-five percent of maximum dry density, and that compaction is what lets it support a footing or a slab. If a pad is built on loose fill, it settles, and the crack shows up in the concrete a year later.
Crushed aggregate base is angular crushed stone that locks together when compacted, which makes it the go-to subbase under a driveway, a gravel road, or a paved surface. It drains well and spreads load. It is a different material from fill for a different purpose, and paying for stone where plain fill would do is a common way budgets creep. Our site preparation and grading work sorts out which layer goes where before anything gets ordered.
On the soft or clay-heavy soils around Benton County, a layer of geotextile separation fabric between the subgrade and the aggregate base keeps the two from mixing. Without it, stone slowly pumps down into soft soil under traffic and the base thins out. The fabric is cheap insurance that keeps a driveway subbase doing its job for years.
Screened topsoil is not a structural material at all, and it belongs on top after the grading and compaction are done. It goes back on for the finish grade so the site can be seeded or sodded. Placing it too early, under areas that will carry load, just creates soft spots you have to dig back out.
The cheapest way to handle material is to plan it before the machines arrive: what gets stripped, what gets compacted, what gets hauled in, and what goes back on top. That plan is part of every walk-through we do. If you are weighing a project, contact us and we will read your site and lay out the material and machine time in writing.

Seahaveninc provides land excavation in Bentonville, AR, handling site preparation and grading, land clearing and grubbing, foundation and basement digs, utility trenching, drainage and erosion control, and structural fill with hydraulic excavators, crawler dozers, and skid steers. Whether you are opening a wooded parcel or shaping a pad for a new slab, we move the dirt to match the engineer's grading plan and leave a subgrade you can build on. Crews run laser and GPS grade control, and every dig starts with an 811 locate before a bucket touches ground near SW 8th Street or any other line in town.
Not all earthwork is the same, and the type of project drives the machines, the material, and the schedule. A foundation excavation is a precise dig to a plan depth with over-dig for the forms. A land clearing job is brush, stumps, and grubbing below the surface before anything else happens. A trenching run for water or sewer needs proper bedding and, in any cut five feet or deeper, a trench box or benching per OSHA Subpart P. We size the approach to the work in front of us rather than forcing one method onto every lot along Walton Boulevard.
Material is the other half of the job, and it is where a lot of budgets go sideways. Fill dirt fills a void, but engineered structural fill placed in controlled lifts and compacted to ninety-five percent of maximum dry density is what carries a footing. Crushed aggregate base builds a stable driveway subbase, geotextile fabric separates it from soft soil, and riprap armors a slope against washout. Screened topsoil goes back on last for the finish grade and seeding. We walk you through which material each part of your site actually needs so you are not paying for stone where dirt would do.
Bentonville sits on rolling Ozark ground in Benton County, and the terrain matters. Lots near the Historic Square and out toward Centerton drain differently than the newer subdivisions off John DeShields Boulevard, and rock is never far below the surface here. We read the site, plan the cut and fill balance to keep haul trips down, and grade positive slopes away from the structure so water leaves the pad instead of pooling on it. The result is a lot that is level, drains right, and is ready for the concrete crew that follows us onto ZIP 72713.
One local crew for the full sequence of site work, from the first tree down to the finish grade.
Clearing, topsoil stripping, cut and fill, and rough-to-finish grading that shapes a raw parcel to the grading plan with build-ready pad elevations and drainage slopes.
Removing trees, brush, and undergrowth, then grubbing stumps and roots below the surface, with haul-off or on-site mulching to open a wooded lot for construction.
Digging footings, crawl spaces, and full basements to plan depth with over-dig for forms and a compacted, level bearing surface for concrete.
Trenches for water, sewer, gas, and electrical with proper bedding and backfill, using a trench box or benching in any cut five feet or deeper per OSHA.
Positive grading away from structures, swales and French drains, plus silt fence and inlet protection to meet stormwater and SWPPP requirements.
Subgrade compaction, geotextile separation fabric, and placement of crushed aggregate base to build a stable, well-draining gravel drive or private road.
We run our machines throughout Bentonville and the surrounding Benton County towns, from the Historic Square out to the newer subdivisions and the acreage past the city limits.

Excavation pricing comes down to two things: how many hours the machines run and how much material moves on or off the site. Hourly machine work covers small digs and cleanup, grading is priced by the square foot, and clearing is priced by the acre. Rock, poor access, and long haul distances push a job higher, while a balanced cut and fill that keeps dirt on site keeps it lower. The ranges below are typical for the Bentonville area, and we put the firm number in writing after we walk your lot.
Ready to move some dirt? We will walk your parcel, read the soil and the slope, plan the cut and fill, and hand you a clear written estimate that spells out the material and the machine time. From the first tree cleared to the final compacted grade, one Bentonville crew handles the whole sequence and calls the 811 locate before we start.
