Bulk Material Delivery in Amity, PA

Where does the water go after it leaves your roof and driveway? That question drives most orders for gravel and aggregate delivery in Amity, PA, where heavy rain and snowmelt run down steep hillsides. Pennsylvania Rock Supply delivers 2A modified, clean washed stone, sand and soil in bulk by the ton, and the material that moves water is the material this ground needs.

Materials for Amity Projects

Drainage work starts with clean stone, not base stone. Clean stone has no fines, so water passes through instead of pooling. Order it by size, from the coarsest down to the finest, and match the size to the job in front of you.

For a French drain, a drywell or a downspout run, 2B stone is the workhorse. It is washed crushed stone about three quarters of an inch, and because the fines are washed out, water moves through it and it never packs into a solid wall. Where a wall needs backfill, #57 stone does the same job at the same size. #4 stone handles the coarser end: underdrains, construction entrances and wet subgrade that needs stabilizing before anything goes on top.

Once the drainage layer is set, cap it. #8 Crushed Stone, also called 1B, is the small clean chip that finishes walkways and beds. Screenings pack firm under pavers and flagstone and bed pipes and conduit. If you are building a base rather than moving water, 2A Modified is the standard Pennsylvania base stone, crushed stone with the fines left in so it compacts hard under a driveway, a parking pad or a shed pad.

Ground and Conditions in Amity

Amity sits in the Western Pennsylvania plateau hills, where flat-lying shale, siltstone, sandstone and claystone have weathered into silty, clay-rich soils on hilly ground cut by steep valleys. Water soaking into clay layers on slopes is the main landslide trigger here, so where roof and drive runoff is sent matters on a hillside lot.

That makes drainage stone an order you place early, not last. Send downspouts and driveway runoff into a clean stone run or a drywell and you keep that water off the clay instead of letting it soak in. This is also why the working season is timing: base, driveway and paver work runs from spring, once the ground has thawed and dried, into late fall, and the long wet spells and rain on snow of winter are when hillside ground is most likely to move.

Winter adds freeze-thaw cycles to the list. Clay-rich soils that stay wet soften and heave, and a thin or poorly drained base breaks up under that movement. The frost depth commonly runs about 36 inches, set by each municipality, but the practical point is simpler: get the water out of the base and the base holds.
