Order Gravel, Stone and Soil in Addison, PA

What do you need to raise a low building pad or firm up a soft drive in Addison? Fill dirt first, then 2A modified on top. Pennsylvania Rock Supply sells gravel and aggregate delivery in Addison, PA, and 2A modified is the base stone buyers here ask for by name.

Ground in this part of Somerset County sits on thin, stony upland soils cut by steep valleys, so grade work usually starts with fill.

If a steep drive or a narrow valley road makes access tight, tell us the setup when you schedule the delivery.

Materials for Addison Projects

Most jobs here start below the surface. Fill dirt raises grade and backfills low spots, and 2A modified goes over it to build the pad or drive that carries the load.

• Fill Dirt for raising grade, filling low spots and backfilling before a base goes down.
• 2A Modified, the standard Pennsylvania base stone, crushed stone with the fines left in so it compacts hard under driveways, pads and shed bases.
• 2B Stone, clean washed stone with no fines, for drive bases in wet areas and drainage behind walls.
• Top Soil for final grading and lawns once the base is set.

Match the material to the project. A driveway gets 2A modified as the base, then a clean stone or driveway gravel on top. A patio or walkway gets 2A modified under it, with screenings or stone dust for the bedding layer.

For a drain, french drain or downspout run, use clean stone such as 2B or #57 stone so water moves through instead of packing tight.

Sand and soil round out the list: Washed Sand for concrete and bedding, Garden Soil for raised beds, and Shredded Mulch for beds and tree rings.

Ground and Conditions in Addison

The ground here is sandstone, siltstone, shale and conglomerate under thin to moderately deep, stony soils. Broad uplands and wide ridges are cut by deep, steep-sided valleys, and old mine ground appears in parts of the zone.

That shape matters for what you build. Rain and snowmelt run fast off the steep valley sides and concentrate into narrow valleys, roadside ditches, culverts and low drives. An under-built base on a slope or a low spot breaks up fast.

Cold winters bring repeated freeze-thaw cycles, and frost depth here commonly runs 36 to 42 inches, with the deeper figures in the mountains. A thin base with poor drainage will not hold through that.

Keep a drainage layer in the plan where water collects, and put base stone down only on thawed, dry ground. Winter snow and frozen ground limit base, driveway and paver work to the thawed months from spring into fall.
