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

Crushed stone has angular, broken faces, so it locks together and compacts. Natural Pea Gravel is rounded natural stone, which stays loose underfoot and drains well but will not form a firm base. That is why 2A modified goes under a driveway and Natural Pea Gravel goes on a walkway or a play area.

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

Either works, and the calculator lets you enter the measurements you have and settles the quantity. Stone and gravel are usually ordered by the ton, while soil, sand and mulch are often ordered by the yard. Pick whichever unit you already have figured and check out.

Which stone is best for drainage in Franklin County?

Clean stone is the answer, because water moves through it instead of pooling. 2B stone is the common choice for French drains and drainage behind retaining walls. #67 stone works where a slightly smaller clean stone is wanted.

Franklin County Landscape Rock and Gravel, PA

Pennsylvania Rock Supply handles gravel, stone and aggregate delivery in Franklin County, PA. Local crews here build almost everything on 2A modified, the crushed stone with the fines left in so it compacts hard. It carries driveways, parking pads and shed bases across the county.

The ground under those jobs is folded bedrock. Long sandstone ridges hold thin, stony soils, and the valleys are floored by shale or by limestone and dolomite that weather to clay.

Ground Conditions Across Franklin County

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.

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, so a base that drains well matters more than a deep one.

Rain and snowmelt run off steep ridge slopes into the valleys. In limestone and dolomite valleys, runoff concentrated from roofs, gutters and drives can open sinkholes, so moving water away from a structure is part of the job.

That same runoff scours roadside ditches, culvert outlets and gravel drives. Stream banks cut back during heavy rain and snowmelt, which is where rip rap comes in.

Materials Delivered in Franklin County

Materials are grouped here from coarsest to finest, with what each size is good for.

2A Modified gets the most attention for good reason. It is the standard Pennsylvania base stone. The trade name adds extra fines to that base. Order it for a driveway, a parking pad, or the base under a shed or patio.

Above that base, clean stone handles water. 2B Stone is what most yards call 3/4 inch clean stone. #57 Stone and #67 Stone both work for drainage and retaining wall backfill. The small clean chip, about half an inch and down, is sold here as #8 Crushed Stone, or 1B.

Choosing the Right Material

Start with the job, then match the size. A compacted base wants 2A modified. A drainage layer wants clean stone such as 2B. A walkway surface wants 1B or screenings.

Neighbouring counties show how the choice shifts. Adams County sits in South Central Pennsylvania on Southeastern Piedmont and Delaware River lowland ground, where loamy upland soils, red shale and sandstone lowlands and limestone valleys that weather to heavy clay all change how a base holds up.

That heavy clay drains slowly, so a drainage layer and clean stone matter more there than a thicker base. Huntingdon and Juniata counties share Franklin County's folded bedrock ground, so the material choice is similar and the projects are much the same.
