Order Gravel, Stone and Soil in Orrstown, PA

Start with the calculator, not a guess. Size your gravel and aggregate delivery in Orrstown, PA by the ton or the yard, then let Pennsylvania Rock Supply drop it where the work is. Most jobs here start with 2A modified for the base, then finish with decorative stone, soil or mulch on top.

Orrstown sits in Franklin County, where the valleys between the ridges carry shale and limestone ground that weathers to clay. That clay holds water, so a base built thin will move under a truck.

Delivery to Orrstown and the Surrounding Area

Order online and pick your quantity in tons or yards. The calculator takes your measurements and gives you a number to order, so you are not guessing at the pile size. Choose your delivery date at checkout and a dump truck brings the load to your site.

Bulk delivery covers Orrstown and the rest of Franklin County, including Chambersburg, Waynesboro, St. Thomas, Greencastle and Fayetteville. Think about where the truck can reach before you order. A driveway pad, a bed edge or a ditch line all work as a drop point if the truck can get to it and the ground is firm.

Materials for Orrstown Projects

Decorative work is where most Orrstown yards start, and the base under it decides how it looks in three years. Beds, borders and dry creek beds all need a compacted layer beneath the stone, or the stone sinks into the clay.

For dry creek beds and heavier erosion work, Large River Rock locks together and stays put when water runs. River Rock suits decorative beds and borders. Both are rounded natural stone, so they stay loose underfoot rather than packing hard.

Ground cover and walkways call for a smaller chip. #8 Crushed Stone, the small clean chip Pennsylvania yards call 1B, works for walkways and decorative topping. 3/8" Natural Pea Gravel is the rounded option for play areas and paths.

Under all of it, order 2A Modified. It is crushed stone with the fines left in, so it compacts hard and holds a bed edge. Top Soil and Shredded Mulch finish beds and tree rings once the stone is set.

Ground and Conditions in Orrstown

The ground here is folded bedrock: sandstone ridges above, shale or limestone valleys below. Valley soils weather to clay, and clay does not drain. An under-built base sits on that clay and heaves once the freeze-thaw cycles start.

Rain and snowmelt run off the steep ridge slopes and concentrate in the valleys. Around roofs, gutters and drives, that concentrated runoff is what opens sinkholes in the limestone and dolomite ground. Clean stone such as 2B Stone moves water through instead of holding it, which is why drains and wall backfill call for it.

Runoff also scours roadside ditches, culvert outlets and gravel drives. Armor those spots with RipRap, sold here by R-number, with R-4 for ditches and the larger sizes for banks. Frost depth runs about 36 inches, set by each municipality, so a thin base that holds water will break up over a cold winter.

Time the work for the season. Base, driveway and paver work runs from spring, once the ground has thawed and dried, into late fall. Base stone should not go down on frozen, soft or muddy ground.
