Order Gravel, Stone and Soil in Harmony, PA

Pennsylvania Rock Supply brings gravel and aggregate delivery in Harmony, PA to your driveway, your beds and your job site. Start with 2A modified, the crushed stone with the fines left in that compacts hard. It is the base stone most Pennsylvania yards stock, and it carries driveways, shed pads and patio bases around Butler County.

Harmony sits on hilly ground cut by steep valleys, with silty and clay-rich soils left by weathered shale and sandstone. That ground decides how a base drains and how deep it needs to be.

Delivery to Harmony and the Surrounding Area

Order online and pick your quantity by the ton or by the yard. If you are unsure how much a project takes, run your measurements through the calculator before you check out. Choose a delivery date that works for your schedule, and a dump truck brings the load to your site.

We deliver bulk loads throughout Harmony and Butler County, including Butler, Zelienople, Slippery Rock, Evans City and Saxonburg. Truck access matters more than distance on hillside lots, so tell us where the pile should land when you order.

For a bed or a dry creek bed, a few tons usually covers the work. For a driveway, most buyers order by the full load. Ordering early in the season keeps your project moving.

Materials for Harmony Projects

The materials that finish a yard are the ones buyers ask about here. Decorative stone, bed cover and drainage rock do the visible work, and each one has a job it does better than the rest.

• River Rock: decorative beds, borders and dry creek beds. Rounded stone that looks finished and moves water along a swale.
• Large River Rock: heavier dry creek beds and erosion work on slopes where the smaller stone would wash out.
• Shredded Mulch: beds and tree rings, holding moisture through the summer and keeping weeds down.
• 3/8" Natural Pea Gravel: walkways, play areas and light drainage. Rounded natural stone, so it stays loose underfoot.
• Top Soil: lawns, final grading and bed prep, screened to take out stones and roots.

A dry creek bed starts with 2A modified shaped into the swale, then river rock on top. The base sets the line; the rock hides it and lets water run. Beds that sit against the house want shredded mulch, while a border along a walk reads better in river rock.

Ground and Conditions in Harmony

Local soils are silty and clay-rich, weathered from shale, siltstone, sandstone and coal beds. Wet clay softens and heaves through repeated freeze-thaw cycles, so a thin or poorly drained base breaks up fast. Build the base thick and get water out of it.

Water is the other half of the job. Heavy rain and snowmelt run down steep hillsides, and water soaking into clay layers on slopes is the main trigger for slumping and landslides in this part of the state. Where roof and drive runoff goes matters on a hillside lot.

Use clean stone where you need water to move. 2B stone and #57 stone have no fines, so water passes through and the stone stays put. Screenings pack firm for paver and flagstone bedding. RipRap armors ditch banks and culvert outlets against scour.

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