Planning a driveway rebuild, a patio base or a drainage run? Pennsylvania Rock Supply handles gravel and aggregate delivery in Donora, PA, and 2A modified is the stone most jobs here start with. It is crushed stone with the fines left in, so it compacts hard and holds up on the clay-rich ground that covers the hills around Washington County.

Materials for Donora Projects

Driveway and base work leads here, because that is what most local ground demands. Start with 2A modified over fill dirt, then top it with a surfacing stone.

2A modified is also called modified stone, and it is the base stone Pennsylvania yards sell for driveways and pads. If you are working a low or wet spot, switch the base layer to 2B stone: it is washed clean with no fines, so water moves through instead of sitting.

For drainage and concrete work, #57 Stone and #67 Stone cover retaining wall backfill and mixes. #8 Crushed Stone, the small clean chip yards call 1B, works for walkways and decorative topping. Bedding under pavers and flagstone takes Screenings, which pack firm.

Sand and soil round out most orders. Mason Sand handles mortar and paver joints, Washed Sand goes under slabs and pavers, and Garden Soil fills raised beds. Decorative beds take River Rock or Natural Pea Gravel.

Ground and Conditions in Donora

Heavy rain and snowmelt run down steep hillsides here, and water soaking into clay layers on slopes is the main landslide trigger in this part of Pennsylvania. Where your roof and drive runoff go matters on a hillside lot.

The ground itself is flat-lying shale, siltstone, sandstone and clay beds weathered into silty, clay-rich soils, and many communities sit over old underground coal mines. Wet clay softens and heaves through repeated freeze-thaw cycles every winter. Frost depth is commonly about 36 inches, set by each municipality.

That is why a thin or poorly drained base breaks up. A clean stone drainage layer under or beside the base, such as 2B or Drain Rock, gives water somewhere to go instead of sitting in the fines. On steep slopes and ditch lines, armoring with RipRap in the R-4 size for ditches and larger R-5 to R-7 sizes for banks cuts down on washouts after a storm.

Timing follows the weather. 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.

Have the drop spot ready before the truck arrives. Clear the area, mark anything low that should not be driven over, and make sure the truck can reach the pile location. A driveway or pad that is soft after rain can limit where the load goes.
