On these hillsides, water is the job. Clay-rich ground sheds roof and drive runoff downslope fast, so where that water goes matters as much as what you put on top of it.

Materials for Pittsburgh Projects

Drainage material is the first order of business on most Pittsburgh jobs. Clean washed stone lets water pass instead of trapping it, and that is what keeps a hillside lot from turning into a mud problem.

For French drains, drywells and downspout runs, 2B Stone does the heavy lifting. It is a clean, washed 3/4 inch crushed stone with no fines, so water moves through it and it never packs hard.

Where you want a smaller clean chip, #8 Crushed Stone (sold locally as 1B) handles walkways, decorative topping and tight drainage runs. For joint and bedding work a step finer, #89 Crushed Stone fits the bill. Drain Rock covers downspout runs and drainage behind walls, and Pennsylvania yards usually fill that order with clean stone such as 2B.

Below the clean stone sits the base. 2A Modified is the standard Pennsylvania base stone: crushed stone with the fines left in, so it compacts hard under driveways, parking pads, shed pads and patio bases. You will also see it written as modified stone. Crusher Run is the same family of material, though most buyers here ask for 2A modified for a compacting base.

Fix the grade before any of that goes down. Fill Dirt raises low spots and backfills ahead of a base or topsoil layer, and Top Soil finishes lawns and beds once the stone work is done.

Delivery to Pittsburgh and the Surrounding Area

Order online and pick your quantity by the ton or the yard. Size the load with the calculator if you are unsure, then choose a delivery date at checkout. A dump truck brings the material to your site, and you dump where the truck can reach the pile.

We deliver across Pittsburgh and Allegheny County, including Bethel Park, Monroeville, Allison Park, West Mifflin and McKeesport. On a hillside lot, think about where the truck can set the pile before you order. Stone dropped at the top of a slope is hard to move back up.

Ground and Conditions in Pittsburgh

This is Western Pennsylvania plateau hills country: flat-lying shale, sandstone, claystone and coal beds weathered into silty, clay-rich soils, cut by steep valleys. Many communities here sit over old underground coal mines. That ground drains slowly and moves when it stays wet.

Heavy rain and snowmelt run down the steep hillsides, and water soaking into clay layers on slopes is the main landslide trigger in and around Pittsburgh. That is why roof and drive runoff needs a destination, not just a spot to pool. Stream bank scour and ditch washouts after heavy rain follow the same pattern.

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 a delivery around a dry stretch pays off. Repeated freeze-thaw cycles every winter soften clay-rich soils that stay wet and heave them, and a thin or poorly drained base breaks up. Frost depth is commonly about 36 inches, set by each municipality.
