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

What holds a hillside driveway or a ditch bank together once the rain starts? Gravel and aggregate delivery in Coolspring, PA starts with the right coarse stone, and Pennsylvania Rock Supply delivers it by the ton. On ground cut by steep valleys, where clay-rich soils soften and move, 2A modified builds the compacted base while clean stone handles the water.

Materials for Coolspring Projects

Erosion work on slopes, swales and stream banks drives most orders here. Coarse, clean stone lets water pass instead of building pressure behind it. Start with the largest material and work down to the fines you bed pavers on.

For a ditch or swale, rip rap is the standard answer, and Pennsylvania yards sell it by R-number. RipRap comes in R-4 for ditch lines and R-5 and larger for banks and streambanks. Where a slope keeps slumping, #4 stone goes in first as a heavy underdrain layer.

Behind a retaining wall or under a wet drive base, you want 2B Stone. It is clean and washed with no fines, so water moves through it and it does not pack hard. For tighter drainage and concrete work, #67 Stone does the same job in a smaller size, and Drain Rock covers French drains and downspout runs.

Decorative work uses the smaller sizes. #8 Crushed Stone tops walkways and plays a part in asphalt and concrete mixes, while River Rock and Large River Rock line dry creek beds and borders that also carry runoff.

Bases and surfacing round out an order. 2A modified, also called modified stone, is the standard Pennsylvania base, crushed stone with the fines left in so it compacts hard under driveways, parking pads and shed bases. Driveway Gravel surfaces an existing drive, and Top Soil finishes lawns and beds after the stone is in.

Ground and Conditions in Coolspring

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. Time a delivery for the dry stretch you are actually working in.

The ground here is flat-lying shale, siltstone, sandstone, claystone and coal beds weathered into silty, clay-rich soils. Heavy rain and snowmelt run down steep hillsides, and water soaking into clay layers on slopes is the main landslide trigger. Where roof and drive runoff is sent matters on hillside lots, and clean stone outlets give that water somewhere to go.

Repeated freeze-thaw cycles every winter soften wet clay soils and heave them, so a thin or poorly drained base breaks up. Frost depth is commonly about 36 inches, set by each municipality, which is why drainage under a base carries as much weight as the stone on top.
