Gravel and Aggregate Delivery in Eighty Four, PA

If you are planning a driveway, a parking pad, a patio base or a drainage run in Eighty Four, the job starts with the right stone under it. Pennsylvania Rock Supply delivers 2A modified and the rest of the aggregate yard straight to your site. This is clay-rich ground, so what you put down first decides how the surface holds up.

Materials for Eighty Four Projects

Most work around here starts with 2A modified. It is crushed stone with the fines left in, so it compacts hard and locks together under a driveway or a shed pad. That is the Pennsylvania base stone, and it is what you want under anything that carries weight.

From there you pick the material by what it has to do.

• 2A Modified is the standard base for driveways, parking pads and patio or shed bases. It sets up firm once it is watered and rolled.
• 2B Stone is clean washed 3/4 inch stone with no fines. Water moves through it, so it goes in French drains, behind retaining walls and on wet drive bases.
• Driveway Gravel is the surfacing layer you put over a compacted 2A modified base to finish an existing drive.
• Screenings are the fine stone dust and chips that pack firm under pavers and flagstone.
• Top Soil is screened to take out stones and roots, for lawns and final grading after the base work is done.

Numbers like #57 and #67 are how clean stone is specified and sold locally, and they work for drainage and concrete. Riprap, sold by R-number, armors ditch banks and culvert outlets.

Ground and Conditions in Eighty Four

Eighty Four sits in Washington County on the Western Pennsylvania plateau hills. The ground under it is flat-lying shale, siltstone, sandstone, claystone and coal beds, weathered into silty and clay-rich soils on hilly ground cut by steep valleys.

That matters most when it rains. Heavy rain and snowmelt run down steep hillsides, and water soaking into clay layers on slopes is the main trigger for ground movement. Where your roof and drive runoff gets sent is a real decision on a hillside lot, not an afterthought.

So the base has to drain as well as compact. A compacted 2A modified layer with a clean stone edge or a French drain carrying water away holds up far better than a base that traps it.

Winter is the other half of it. Repeated freeze-thaw cycles soften and heave clay-rich soils that stay wet, and a thin or poorly drained base breaks up over a season. Base, driveway and paver work runs from spring, once the ground has thawed and dried, into late fall. Long wet spells and rain on snow are when hillside ground is most likely to move, so timing your excavation around the forecast pays off.

A dump truck brings the material to your site and tips it where you want it. Have the drop spot clear and reachable, with room for the truck to pull in and out and no overhead wires in the way. Think about where you want the pile, since moving it twice is work you do not need.
