2A Modified, Sand and Gravel Delivery in Elk County, PA
If you are planning a driveway, a patio base or a drainage run, you need gravel, stone and aggregate delivery in Elk County, PA. Pennsylvania Rock Supply brings bulk material to your site. Most jobs here start with 2A modified, the crushed stone with the fines left in so it compacts hard. On the steep ground around St. Marys and Ridgway, water off the hillsides decides how a base holds up.
Materials Delivered in Elk County
You order by the ton or the yard, and the load shows up on a dump truck. Here is how the main families break down for local work.
2A modified carries the base work here. Local yards still use the older names alongside those numbers, so 2B means #57 and 1B means #8. Ask for 2A Modified and you get the trade version of a 2A-type base with extra fines added.
For drainage, reach for clean stone instead. #67 Stone works where you want a slightly smaller clean stone than #57. #89 Crushed Stone handles joints and tight bedding. #4 Crushed Stone is the large clean stone for construction entrances, subgrade stabilization and underdrains.
Sand and soil round out most orders. Mason Sand goes into brick and block mortar, paver joints and play areas. Washed Sand is the concrete and bedding sand. Fill Dirt raises grade and backfills before a base or topsoil goes down. River Rock and Shredded Mulch finish beds and borders.
Ground Conditions Across Elk County
This county spans two ground zones, and water behaves differently in each. In the plateau hills around St. Marys, Kersey, Weedville and Byrnedale, heavy rain and snowmelt run down steep hillsides. 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.
In the high plateau and Allegheny Mountains around Ridgway, Johnsonburg, Wilcox and De Young, rain and snowmelt run fast off steep valley sides. That sends concentrated flow into narrow valleys, roadside ditches, culverts and low drives. Runoff off those slopes gullies gravel roads and ditch lines, and scours stream banks. That is why clean stone belongs in drainage runs and why ditch and culvert outlets get armored.
Winter sets the schedule. Snow and frozen ground limit base, driveway and paver work to the thawed, dry months from spring into fall. Base stone should not go down on frozen or muddy ground. Freeze-thaw cycles come every winter, and the higher ground runs cooler and wetter than most of the state, so a thin or poorly drained base breaks up. Frost depth is commonly 36 to 42 inches, set by each municipality, with the deeper figures in the mountains.

Choosing the Right Material
Neighbouring counties sit on similar ground, so the material choice shifts less than you might expect. McKean County and Cameron County both sit in the North-central high plateau and Allegheny Mountains, with stony soils on broad uplands cut by steep-sided valleys. That ground is much like Elk County's mountain side, so 2A modified for bases and clean stone for drainage carry the same jobs.
Clearfield County spans both the Western Pennsylvania plateau hills and the high plateau, so its ground overlaps both of Elk County's zones. Where a neighbor shares your zone, the difference is usually the project, not the stone: more driveway and pad work in one place, more ditch and culvert work in another.
Sort your job before you pick. A driveway or patio base wants 2A modified, compacted in lifts. A french drain, downspout run or wall backfill wants clean stone such as 2B. Bedding and joints want screenings. Lawns and beds want topsoil, garden soil or mulch.
