Large River Rock and Bulk Aggregates for Airville, PA

Pennsylvania Rock Supply handles gravel and aggregate delivery in Airville, PA. The base stone most buyers here ask for is 2A modified, crushed stone with the fines left in so it compacts hard under driveways, parking pads and shed bases.

Airville sits in York County, where storm runoff from paved ground scours stream banks and washes out ditches and culvert outlets. Coarse stone is how you armor those spots.

Materials for Airville Projects

Slope, swale and bank protection starts with size. Coarse, clean stone locks together and holds ground in place where water moves fast. Lined out from coarsest to finest, here is what works locally.

Coarse stone for slope and bank work

• RipRap: Pennsylvania yards sell it by R-number, with R-4 for ditches and larger R-5 sizes for banks and streambanks.
• #4 Crushed Stone: large clean stone for construction entrances, subgrade stabilization and underdrains.
• Railroad Ballast: heavy coarse clean stone for hard standing, track beds and severe drainage.

Clean stone for drainage

Clean stone has no fines, so water moves through it instead of packing tight. That makes it the right call behind a retaining wall or in a French drain.

• 2B Stone: washed 3/4 inch clean stone for French drains, shed pads and drive bases in wet areas.
• #57 Stone: the same size as 2B, used for drainage, wall backfill and concrete aggregate.
• Drain Rock: clean stone for French drains and downspout runs.

Base and finish stone

For a compacted base, 2A modified is the standard Pennsylvania choice, and buyers here usually ask for it instead of crusher run for the same job. 2A Modified goes down under driveways, parking pads and patio bases.

On top of that base, Driveway Gravel surfaces an existing drive or tops compacted stone. For paths, Walkway Gravel gives a finer, walkable surface.

Small clean chips and bedding

Smaller clean stone handles walkways, tight bedding and decorative work. 1B Stone, about half an inch and down, suits walkways and decorative topping.

Screenings pack firm under pavers and flagstone, and River Rock and Large River Rock finish beds, borders and dry creek beds that carry runoff.

Ground and Conditions in Airville

Base, driveway and paver work runs from spring, once the ground has thawed and dried, into late fall. Base stone should not go down on frozen, soft or muddy ground.

This zone is mixed Piedmont ground. Loamy soils weathered from schist and gneiss sit on the uplands, with red shale and sandstone in the lowlands and limestone valleys whose soils weather to heavy clay.

Winters bring repeated freeze-thaw cycles, so a thin or poorly drained base can heave and break up. Frost depth runs about 30 to 36 inches and is set by each municipality.

Heavy summer storms and spring rain run off built-up ground and are managed under municipal stormwater rules. Over limestone, runoff concentrated from roofs, gutters and drives can open sinkholes, so route water away from the house.
