Bulk Aggregates for Pathways in Harwick, PA

Pennsylvania Rock Supply handles gravel and aggregate delivery in Harwick, PA for driveways, drainage and yard projects. We stock 2A modified, the base stone this market asks for by name, along with clean stone, sand, topsoil and decorative rock. Harwick sits in Allegheny County on hilly ground cut by steep valleys, so what you put down and how water moves off it both matter.

Ground and Conditions in Harwick

Under Harwick you have flat-lying shale, siltstone, sandstone, claystone and coal beds weathered into silty, clay-rich soil. That clay holds water, and on a slope it softens and can slump after heavy rain or a rain-on-snow stretch.

A thin base shows its weaknesses fast here. Freeze-thaw cycles every winter heave wet clay, and a driveway or path that was never drained breaks up along the edges first.

The answer is a compacted base with a drainage layer and a plan for roof and drive runoff. Frost depth runs about 36 inches, set by each municipality, so base depth is worth confirming with your code official before you order.

Timing matters too. Base, driveway and paver work runs from spring, once the ground has thawed and dried, into late fall. Long wet spells are when hillside ground is most likely to move.

Materials for Harwick Projects

Paths and walkways are where fines and screenings do the most work. Screenings, also called stone dust, pack firm under pavers, flagstone and walkway surfacing, and they bed pipe as well. Order Screenings for a walkway base that will not shift underfoot.

On top of that base, the surface you pick decides how the path feels and how it drains. Here are the ones Harwick buyers ask for:

For the base under all of it, 2A modified is the standard. Crusher run does a similar job, though most Pennsylvania buyers ask for 2A modified instead. Where a path or patio base sits in a wet spot, switch to 2B stone, a clean washed stone with no fines, so water passes through instead of pooling. #57 stone and #67 stone cover the same drainage role at slightly different sizes.

Beyond paths, we carry rip rap for ditch and slope armoring, river rock and large river rock for dry creek beds, mason sand and washed sand for mortar and bedding, plus topsoil, garden soil, fill dirt and shredded mulch.

You order online, choose a quantity by the ton or by the yard, and pick your delivery date at checkout. A dump truck then brings the load to your site. If you are unsure how much you need, the calculator sizes the load for you.
