Start with 2A modified. It is the standard Pennsylvania base stone, crushed stone with the fines left in so it compacts hard. On the clay-rich ground around Punxsutawney, Brookville and Reynoldsville, that hard base is what keeps a drive from rutting.
Materials Delivered in Jefferson County
2A modified leads every order here. 2A modified is the trade name for a 2A-type base with extra fines added.
Order 2A modified for driveways, parking pads, and shed or patio bases. Layer it, wet it, and compact it. Below that, fill dirt raises grade and backfills low spots before the base or topsoil goes down.
Round out a load with Mason Sand for mortar and joints or Washed Sand for concrete and paver bedding. Add River Rock for beds and dry creek beds.
Choosing the Right Material
Ground next door tells you what to order. Indiana County spans the same two zones as Jefferson, so the base and drainage choices run close to yours and the projects do too. Armstrong County sits in the plateau hills, with the same clay-rich soils and old mine ground under many communities, so 2A modified and clean 2B cover the same jobs.
Forest County sits on the high plateau and Allegheny ground, with thin, stony soils on broad uplands cut by steep valleys. There, drainage stone and slope armoring carry more of the load and base stone matters less. In Jefferson, most orders are still base first.
Match the material to the job:
- Drive or pad: 2A modified base, then Driveway Gravel on top.
- Wet ground or drainage: 2B Stone or #67 Stone.
- Walkways: Walkway Gravel or 1B chip.
- Bank or ditch: R-4 to R-5 RipRap.
Ground Conditions Across Jefferson County
A thin or poorly drained base breaks up here. Clay-rich soils across the plateau hills hold water, soften, and heave through repeated freeze-thaw cycles every winter. Frost depth runs about 36 inches, set by each municipality.
Up on the high plateau around Sigel, ground runs cooler and wetter, with frost depth commonly 36 to 42 inches. Build the base thick enough and drain it, and it holds.
Water is the other half. Heavy rain and snowmelt run down steep hillsides, and water soaking into clay layers on slopes is the main landslide trigger. Route roof and drive runoff away from the slope. In the narrow valleys, concentrated flow hits ditches, culverts and low drives, so line them with clean stone.
Timing matters. Base, driveway and paver work runs from spring, once ground has thawed and dried, into late fall. Do not put base stone down on frozen or muddy ground.
