Large River Rock, Stone and Soil Delivery in Tarentum, PA

Pennsylvania Rock Supply handles gravel and aggregate delivery in Tarentum, PA, from single loads to full site packages. The base stone most jobs here start with is 2A modified, crushed stone with the fines left in so it compacts hard under driveways, parking pads and shed bases. On ground this steep and this wet, what you put on top matters as much as what you put underneath.

Materials for Tarentum Projects

Slope, swale and bank work is the first thing to plan for around here. Heavy rain and snowmelt run down steep hillsides, and the wrong stone lets that water cut a channel instead of shedding it. Coarse, clean stone is what holds a slope together, so we list materials from coarsest to finest.

Riprap is the heavy option for ditch washouts and streambank scour. R-4 suits ditches, and the larger R-5 through R-7 sizes go on banks where the water hits hardest. For a French drain or the backfill behind a retaining wall, 2B stone is the clean 3/4 inch stone that lets water move through instead of packing tight. Buyers who ask for 57 stone are describing the same clean size.

Above that drainage layer, 2A modified is the standard Pennsylvania base. It is the local name for crushed stone with the fines left in, and it firms up under a plate compactor. Some yards quote crusher run for the same job; here you ask for 2A modified. Screenings, also called stone dust, pack firm under pavers and flagstone and bed a pipe without cutting it.

Ground and Conditions in Tarentum

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 is worth the wait.

The ground here is silty and clay-rich, weathered from shale, siltstone and sandstone, on hilly terrain cut by steep valleys. Clay that stays wet softens and heaves through repeated freeze-thaw cycles, so a thin or poorly drained base breaks up fast. Frost depth is commonly about 36 inches, set by each municipality. Where roof and drive runoff is sent matters on these slopes, which is why clean stone and a drainage layer earn their place.
