Bulk Gravel and Stone Delivery in Clearfield County, PA
For gravel, stone and aggregate delivery in Clearfield County, PA, start by sizing the load with the calculator, then pick the material. Most jobs here come down to 2A modified, the crushed stone with the fines left in that compacts hard. Pennsylvania Rock Supply delivers it to driveways, pads and building sites across the county.
The ground you build on decides the rest. Around DuBois and Clearfield, silty clay soils sit on hilly ground cut by steep valleys, and heavy rain or snowmelt soaks into clay layers on slopes. That is why drainage stone matters as much as base stone on many lots.
Delivery across Clearfield County
You order online, choose a quantity by the ton or yard, and pick a delivery date at checkout. A dump truck brings the load to your site and drops it where you need it. The calculator handles the sizing so you are not guessing at the numbers.
Bulk delivery covers DuBois, Clearfield, Curwensville, Beccaria, Osceola Mills, Houtzdale, Morrisdale, Karthaus, West Decatur, Hawk Run, Grampian, Irvona, Coalport and Grassflat. If your driveway is tight or your ground is soft, say so when you set the drop point.
Materials delivered in Clearfield County
Yards still use the older Pennsylvania names alongside those numbers, so 2B is what #57 is called here and 1B is the local name for #8. Order by the name you know and the load arrives right.
Driveway and base work
2A modified is the standard Pennsylvania base stone. It is crushed stone with the fines left in, so it compacts hard under a drive, a parking pad, a shed or a patio. It is a trade name for a 2A-type base with extra fines.
Fill dirt raises grade and fills low spots before a base goes down. Driveway gravel surfaces an existing drive or tops a compacted 2A modified base.
Drainage work
2B stone is clean, washed crushed stone with no fines, so water moves through it instead of packing. It goes in French drains, behind retaining walls and under shed pads in wet areas.
Drain rock covers downspout runs and drainage behind walls. RipRap armors stream banks, ditches, culvert outlets and slopes, sold by R-number, with R-4 for ditches and larger sizes for banks.
Beds, walkways and sand
1B stone is the small clean chip used on walkways and decorative topping. Screenings, also called stone dust, pack firm under pavers and flagstone. Washed sand beds concrete and pavers, and topsoil finishes lawns and beds.
Ground conditions across Clearfield County
This county spans more than one ground zone, and the two do not behave the same under a truck load.
In the western plateau hills around DuBois, Clearfield, Curwensville and Beccaria, flat-lying shale, siltstone, sandstone, claystone and coal beds have weathered into silty, clay-rich soils. The ground is hilly and cut by steep valleys, and many communities sit over old underground coal mines. Water soaking into clay layers on slopes is the main landslide trigger, so where roof and drive runoff is sent matters on a hillside lot.
Up on the north-central high plateau and Allegheny Mountains near Smithmill, sandstone, siltstone, shale and conglomerate sit under thin to moderately deep stony soils on broad uplands and ridges. Rain and snowmelt run fast off steep valley sides and concentrate in narrow valleys, roadside ditches, culverts and low drives.
Both zones see repeated freeze-thaw cycles every winter. Frost depth is commonly about 36 inches in the plateau hills and 36 to 42 inches in the mountains, set by each municipality. Clay-rich soils that stay wet soften and heave, so a thin or poorly drained base breaks up.
That is the practical case for a well-drained base and a clean drainage layer. Base, driveway and paver work runs from spring, once the ground has thawed and dried, into late fall. Base stone should not go down on frozen or muddy ground.
Choosing the right material
Next door in Centre County, the ground includes Great Valley and Ridge and Valley terrain along with the anthracite coal region, plus the same plateau hills and Allegheny ground you see here. That wider mix of ground can call for different drainage choices than Clearfield County alone.
Cambria County shares the north-central high plateau and Allegheny Mountains and the western plateau hills, so its ground is similar to Clearfield County's. The comparison there is usually project type rather than soil: drives and pads want 2A modified, while slope work wants riprap.
Clinton County takes in the Great Valley and Ridge and Valley ground and the north-central high plateau, so parts of it drain differently than a clay-heavy hillside lot here. In those spots, clean stone for drainage carries more of the job.
On any Clearfield County lot, the order is the same. Fill dirt first for grade, 2A modified for the base, then a clean stone such as 2B or #57 where water needs to move. Match the stone to the job and the ground does the rest.
