2A Modified, Sand and Gravel Delivery in Northampton County, PA
Pennsylvania Rock Supply handles gravel, stone and aggregate delivery in Northampton County, PA for homeowners, contractors and farms. If you are building a drive, a shed pad or a patio base, 2A modified is the stone most local buyers start with. It is the standard Pennsylvania base, crushed stone with the fines left in so it compacts hard.
The ground changes from one end of the county to the other. Folded bedrock and limestone valleys around Bethlehem and Easton, glacial till around Bangor and Mount Bethel, and both shape how deep a base needs to go and how well it drains.
Ground conditions across Northampton County
The problem a thin base shows here is movement. Cold winters bring repeated freeze-thaw cycles, and a shallow layer over wet ground heaves, cracks and ruts by spring.
Around Bangor and Mount Bethel the story is different. Glacial till sits over shale and siltstone, with a dense layer not far below the surface that traps water from fall into late spring. Low spots, drives and footings stay wet, and wetlands are common.
Frost depth in the county is commonly about 36 inches in the valley zone and 36 to 42 inches in the glaciated northeast, set by each municipality. That is a footing depth set by the building official, not a depth for a gravel drive.
The fix is compaction and drainage together. Put 2A modified down on thawed, drained ground and compact it in lifts, and add a clean stone layer where water has nowhere to go.
Timing matters. 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.

Use those names when you order and you will get the right stone.
2A modified is the base stone to know. It is a 2A-type base with extra fines added.
For drainage, 2B and #57 do the work in the wet till ground and behind retaining walls. Around limestone valleys, where sinkholes are a real risk, clean stone and controlled runoff matter more than base thickness. For joints and tight bedding, screenings or #89 crushed stone fill the gap.
Sand and soil round out an order: mason sand for brick and block mortar and paver joints, washed sand for concrete and bedding, topsoil for lawns, and fill dirt for raising grade before a base goes down. Decorative work takes river rock, large river rock and Natural Pea Gravel for beds, borders and dry creek beds.
Delivery across Northampton County
You can order by the ton or by the yard, whichever your project figures call for. The calculator on each product sizes the load for you, so you can match the quantity to the job before you check out. Pick a delivery date at checkout and a dump truck brings the material to the site.
Before the truck arrives, have the drop spot cleared and reachable. A bulk load needs firm, thawed ground and enough room to dump and pull away, which matters most in the glaciated northeast where the ground stays soft into spring. Mark any septic covers, well heads or buried lines near the pile.
Delivery covers Bethlehem, Easton, Northampton and Hellertown in the valley, plus Nazareth, Bath, Walnutport, Cherryville and Danielsville. To the north and east, it reaches Bangor, Pen Argyl, Wind Gap and Mount Bethel.
Choosing the right material
County lines change what you should order, because the ground underneath changes with them. Lehigh County sits in the Lehigh Valley and spans the Great Valley and Ridge and Valley zone along with the Southeastern Piedmont and Delaware River lowland.
Bucks County sits in Southeastern Pennsylvania and spans the Southeastern Piedmont and Delaware River lowland along with the Great Valley and Ridge and Valley zone. Where the Piedmont and lowland ground takes over, the clay-heavy valley base gives way to different drainage behavior, so clean stone under a drive matters more than raw base thickness.
Inside Northampton County the split runs between the valley and the glaciated northeast. Valley projects lean on 2A modified over a compacted, well-drained base, with riprap or clean stone on steep slopes and ditch outlets. In the wet till ground around Bangor and Mount Bethel, plan a drainage layer of 2B or #57 first, then base stone on top.

Sizing the load is the part worth doing first. Use the calculator on each product to work out the ton or yard figure that fits your drive, drainage or bed, then pick a delivery date that suits the schedule.
