2B Stone and Bulk Aggregates for Corsica, PA

Where does the water go after it leaves your downspout? That is the question behind most gravel and aggregate delivery in Corsica, PA, and it is the one Pennsylvania Rock Supply answers every week. On hillside lots here, roof and drive runoff has to be carried away before it soaks into clay. A washed stone trench does that job. 2A modified handles the base work under it.

Materials for Corsica Projects

Drainage drives most orders in Corsica, so start with the clean, washed stone and work down to the fines. Clean stone has no dust left in it, so water moves through instead of pooling. That is the whole reason it gets used behind walls and under downspout runs.

Clean stone for water

2B Stone is your default for French drains, drywells and downspout runs. It is washed 3/4 inch stone with the fines removed, so it drains instead of packing. Pennsylvania yards also call it 2B clean stone or 3/4 inch clean stone.

#57 Stone is the same size class. Use it for retaining wall backfill and underdrains. #67 Stone is a step smaller for tight drainage runs and concrete work where #57 is a little coarse.

Drain Rock covers the same ground for downspout runs and drainage behind walls. RipRap is for ditch and culvert outlets, sold locally by R-number, with R-4 for ditches and the larger sizes for banks.

Base and bedding

2A Modified is the standard Pennsylvania base stone, crushed stone with the fines left in so it compacts hard. It goes under driveways, parking pads and shed bases. Screenings, also called stone dust, bed pavers and flagstone and pack firm.

Fill Dirt raises grade before a 2A modified base goes down, and Top Soil finishes lawns and beds. Shredded Mulch holds moisture in beds through summer.

You order online, choose your quantity by the ton or the yard, and size the load with the calculator before you check out. Then you pick a delivery date at checkout. A dump truck brings the material to your site in Corsica and tips it where you want it.

Pennsylvania Rock Supply delivers across Jefferson County, so a load can go to Corsica or out to Punxsutawney, Brookville, Reynoldsville, Brockway and Falls Creek. If your driveway is steep or narrow, say so when you set the date so the driver knows where the truck can reach.

Ground and Conditions in Corsica

Base, driveway and paver work here runs from spring, once the ground has thawed and dried, into late fall. That window shapes when you order. Long wet spells and rain on snow are when hillside ground is most likely to move.

The ground under Corsica is flat-lying shale, siltstone and sandstone weathered into silty, clay-rich soil, on hilly ground cut by steep valleys. 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.

Freeze-thaw cycles repeat every winter, and clay-rich soils that stay wet soften and heave. A thin or poorly drained base breaks up fast, which is why the clean stone layer goes in first. Frost depth is commonly about 36 inches, set by each municipality, so check with your code official on footing depth.
