Buy #57 Stone in Upper Darby, PA

Planning a driveway, a parking pad, a patio base or a drainage run in Upper Darby? For gravel and aggregate delivery in Upper Darby, PA, Pennsylvania Rock Supply keeps the materials that job actually takes. Most drives and pads here start with 2A modified, the crushed stone with the fines left in that compacts hard under a truck. From there you pick clean stone, sand, soil or decorative rock to finish the work.

Materials for Upper Darby Projects

Base and driveway work leads everything else. 2A modified is the standard Pennsylvania base stone, and it is what you want under a driveway, a shed pad or a patio. It locks up tight once it is watered and rolled. If the ground stays wet or the drive holds water, switch the base to clean stone so water moves instead of sitting.

Pennsylvania yards often get asked for crusher run for the same job. It is a compacting base with fines mixed in, and it works, but most crews here just say 2A modified. For a top coat over a compacted base, driveway gravel gives you the wearing surface, and walkway gravel finishes paths at a finer, walkable size.

Clean, washed stone handles drainage. 2B stone, also called 2B clean stone or 3/4 inch clean stone, has no fines, so it drains and stays loose. Use it in French drains, behind retaining walls and on shed pads in wet spots.

Sand, soil and decorative rock round out most orders in Delaware County:

• 2A Modified for driveways, parking pads and shed or patio bases.
• 2B Stone for French drains, wall backfill and wet drive bases.
• Washed Sand for concrete and bedding under pavers and slabs.
• Top Soil for lawns, final grading and bed prep.
• River Rock for decorative beds, borders and dry creek beds.

Ground and Conditions in Upper Darby

Water drives the work here. Heavy summer storms and spring rain come off roofs, gutters, driveways and built-up ground, and under municipal stormwater rules that runoff has to go somewhere. Where it goes decides what base you buy.

This is mixed Piedmont ground. Uplands carry loamy soils weathered from schist and gneiss, the lowlands run to red shale and sandstone, and limestone valleys weather to heavy clay. A narrow strip along the Delaware River is loose sand and gravel instead of rock. Clay holds water, so a drive cut into it needs clean stone underneath before any 2A modified goes down.

Over limestone, runoff concentrated from roofs, gutters and drives can open sinkholes. That is a limestone-valley issue, not something every property faces, but it is worth knowing before you redirect a downspout or a driveway slope.

The same storm runoff scours stream banks and washes out ditches, culvert outlets and sloped gravel drives. Rip rap armors those spots, with R-4 for ditches and the larger R-5 to R-7 sizes for banks. 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. Winters bring repeated freeze-thaw cycles, and frost depth here runs about 30 to 36 inches, set by each municipality. A thin or poorly drained base can heave and break up even though frost does not reach as deep as it does in most of the state.

Have the drop spot ready. A clear, firm place to dump keeps the truck off soft ground and off anything you do not want buried. If the driveway is tight or the load is going behind a house, say so when you order so the driver knows what they are backing into.
