Large River Rock and Bulk Aggregates for Dillsburg, PA

Pennsylvania Rock Supply handles gravel and aggregate delivery in Dillsburg, PA for driveways, drainage and building pads. Most jobs here start with 2A modified, the crushed stone with the fines left in that compacts hard. This part of York County sits on mixed Piedmont ground, so what the ground does with storm water decides most material choices.

Materials for Dillsburg Projects

Dillsburg sits where storm runoff from roofs, drives and paved ground scours banks, ditches and culvert outlets. Coarse clean stone is the answer for slope, swale and bank protection. The list below runs coarsest to finest, with what each size does.

• RipRap armors stream banks, ditch lines, culvert outlets and sloped drives. Local yards sell it by R-number, with R-4 for ditches and larger R-5 to R-7 sizes for banks.
• #4 Crushed Stone is the large clean stone for construction entrances, subgrade stabilization and underdrains.
• 2B Stone is the clean, washed 3/4 inch stone for French drains, drainage behind retaining walls and shed pads in wet areas. It has no fines, so water moves through it and it does not pack hard.
• 2A Modified is the standard Pennsylvania base stone for driveways, parking pads and shed and patio bases. The fines let it compact hard under a top layer.
• Screenings are fine crushed stone dust and chips that pack firm, used for paver and flagstone bedding, walkway surfacing and pipe bedding.

For a drive that stays put, cap a compacted 2A modified base with Driveway Gravel. For a walkway, Walkway Gravel gives a finer surface underfoot.

Ground and Conditions in Dillsburg

Base, driveway and paver work here 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, because it will not compact and the surface will move later.

Winters bring repeated freeze-thaw cycles. Frost depth runs about 30 to 36 inches and is set by each municipality. A thin or poorly drained base can heave and break up even so, which is why drainage stone under and beside the base matters as much as the base itself.

Storm runoff from built-up ground is the other local driver. It scours stream banks and washes out ditches, culvert outlets and sloped gravel drives. Clean stone and riprap take that energy without silting up. Over limestone valleys, where soils weather to heavy clay, concentrated runoff can open sinkholes, so keeping water moving away from the house matters.
