What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone has angular, fractured faces, so it locks together and compacts hard. Natural Pea Gravel is rounded natural stone, so it stays loose underfoot and shifts under a wheel. Use crushed stone for bases and driveways, and Natural Pea Gravel for walkways, play areas and light drainage where a loose surface is fine.

Should I order material by the ton or by the yard?

Both work. Stone, sand and gravel are usually sold by the ton, while soil, fill and mulch often go by the yard. Enter your project measurements in the calculator and it sets the quantity for you, so you can order whichever unit the material is sold in.

Which stone is best for drainage in Dauphin County?

Clean stone with no fines, so water passes through instead of pooling. In this county that means 2B, which local yards also sell as #57, for French drains, wall backfill and downspout runs. For tighter spots, #67 or #8 Crushed Stone works where a smaller clean stone fits the trench.

Dauphin County, PA Aggregate and Rock Delivery

For gravel, stone and aggregate delivery in Dauphin County, PA, the ground under your project decides the base. Pennsylvania Rock Supply sells bulk material online with delivery across the county. Much of Dauphin County sits on folded bedrock: sandstone ridges with thin, stony soils, and valleys floored by shale or by limestone and dolomite that weather to clay. That mix is why 2A modified is the base most buyers here start with, since the fines let it compact hard over uneven ground.

Materials Delivered in Dauphin County

Yards here still sell stone by the older Pennsylvania names, so you will see 2A modified. Sizes run from the largest clean stone down to the finest bedding material.

2A modified is the trade name for a 2A-type base with extra fines added. It is how base stone is specified and sold locally, and it is the material most drives and pads in the county are built on. Crusher run does the same job, and Pennsylvania buyers usually ask for 2A modified instead.

For water that has to move, use clean stone: 2B Stone for French drains and wall backfill, #67 Stone where a slightly smaller clean stone is wanted, and Drain Rock for downspout runs. Clean stone has no fines, so water passes through and it never packs hard.

Around the house, Top Soil handles lawns and final grading, Garden Soil fills raised beds, and Shredded Mulch holds moisture in beds through summer. Sand follows the same split: Mason Sand for mortar and play areas, Washed Sand for concrete and paver bedding.

Ground Conditions Across Dauphin County

Dauphin County spans two ground zones, and the working season matters as much as the soil. 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.

In the Great Valley and Ridge and Valley zone, covering Harrisburg, Hershey, Hummelstown and Millersburg, rain and snowmelt run off steep ridge slopes into the valleys. In the limestone and dolomite valleys, runoff concentrated from roofs, gutters and drives can open sinkholes, so it pays to move water away from the foundation. Cold winters bring repeated freeze-thaw cycles that heave and break up a thin base or one that holds water. Frost depth is commonly about 36 inches, set by each municipality.

In the Southeastern Piedmont and Delaware River lowland zone, covering Middletown and Highspire, the ground is loamy soils weathered from schist and gneiss on the uplands, red shale and sandstone in the lowlands, and limestone valleys whose soils weather to heavy clay. Heavy summer storms and spring rain run off built-up ground under municipal stormwater rules. Winters bring repeated freeze-thaw cycles, so a thin or poorly drained base can heave and break up, even though frost does not reach as deep here as in most of the state. Frost depth runs about 30 to 36 inches, set by each municipality.

Choosing the Right Material

Neighboring counties show how much the right choice shifts with the ground. Lancaster County sits in the Southeastern Piedmont and Delaware River lowland zone, where soils weather from schist and gneiss on the uplands and heavy clay in the limestone valleys. That heavier clay drains slowly, so drainage stone and a thicker compacted base carry more weight in the plan than they do on Dauphin County's stony ridges.

Schuylkill and Northumberland counties share Dauphin County's Great Valley and Ridge and Valley ground, so the material set is similar. Expect the same 2A modified base, the same clean stone for drainage, and the same rip rap for ditch and bank work. The difference is in the project mix: more culvert outlets and slope armoring where runoff leaves the ridges.
