Bulk Aggregates for Drainage in Clarksville, PA

If you need gravel and aggregate delivery in Clarksville, PA, Pennsylvania Rock Supply supplies bulk stone, sand and soil by the ton or yard. This is hilly ground with clay-rich soils, and heavy rain and snowmelt run fast down the slopes. That makes 2A modified the base most jobs here start with, and it makes clean, washed stone the material that keeps water moving away from the house.

Most Clarksville lots sit on a grade, so where roof and drive runoff gets sent matters as much as what you put under the driveway.

Drainage is the first question on a hillside lot, so it makes sense to work from the coarsest stone down to the fines. Clean stone has no fines left in it, so water passes straight through instead of packing tight. Base stone has the fines left in, so it compacts hard and holds a driveway together.

At the coarse end, RipRap armor stream banks, ditch lines and culvert outlets where runoff scours. Pennsylvania yards sell it by R-number, with R-4 for ditches and the larger R-5 sizes for banks. #4 Crushed Stone works for construction entrances, underdrains and subgrade stabilization, and Railroad Ballast handles hard standing and severe drainage where you need a lot of open void space.

For French drains, drywells and downspout runs, the workhorse is 2B Stone, the clean 3/4 inch crushed stone Pennsylvania yards also call 2B clean stone. Where a slightly smaller clean stone is wanted, #67 Stone and Drain Rock both fit the same drainage jobs.

Smaller clean chips have their own places. #8 Crushed Stone, sold locally as 1B, tops walkways and goes into asphalt and concrete mixes. #89 Crushed Stone washes into tight joints and bedding. Screenings, also called stone dust, pack firm under pavers and flagstone.

Base and surface work comes next. 2A Modified, also called modified stone, is the standard Pennsylvania base, crushed stone with the fines left in so it compacts hard. It goes under driveways, parking pads, shed and patio bases. Fill Dirt raises grade before that base goes down, and Top Soil finishes lawns and beds.

Ground and Conditions in Clarksville

This part of the state sits on flat-lying shale, siltstone, sandstone, claystone and coal beds that have weathered into silty, clay-rich soils. The ground is hilly and cut by steep valleys, and many communities sit over old underground coal mines.

Clay-rich soil that stays wet softens and heaves through repeated freeze-thaw cycles every winter. Frost depth is commonly around 36 inches, set by each municipality. A thin or poorly drained base breaks up under that cycle, which is why the drainage layer and the compaction matter more than the thickness of the surface stone.

Water soaking into clay layers on slopes is the main trigger for the slides and slumping this region sees, so roof and drive runoff should be sent somewhere it can leave the slope. That is the reason a downspout run or a French drain matters here. Base, driveway and paver work runs from spring, once the ground has thawed and dried, into late fall.
