Bulk Gravel and Stone Delivery in Lycoming County, PA
Pennsylvania Rock Supply handles gravel, stone and aggregate delivery in Lycoming County, PA. Base, driveway and paver work here 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. That timing decides most orders, and 2A modified is the material most of them start with.
Ground in the county splits two ways. Around Williamsport and Montoursville the valleys carry shale, limestone and dolomite soils. Up past Cammal and Cedar Run the uplands are stony and the valleys are steep. Both change what you put under a drive.
Ground Conditions Across Lycoming County
A thin base that holds water breaks up first. Cold winters bring repeated freeze-thaw cycles, and that is what heaves and cracks a driveway with too little stone under it or nowhere for water to go.
In the Great Valley and Ridge and Valley zone, which takes in Williamsport, Montoursville, Jersey Shore and Muncy, folded bedrock leaves long sandstone ridges with thin, stony soils. Valleys are floored by shale or by limestone and dolomite that weather to clay. Old strip mines and waste piles break up ground in the anthracite fields.
In the North-central high plateau and Allegheny Mountains zone, which takes in Cammal, Cedar Run, Jersey Mills and Waterville, sandstone, siltstone, shale and conglomerate sit under thin to moderately deep stony soils. Coal beds and old mine ground occur in parts of the zone.
Water drives the fix. On the ridge side, rain and snowmelt run off steep slopes into the valleys, and in limestone and dolomite valleys runoff from roofs, gutters and drives can open sinkholes. Up north, runoff comes fast off steep valley sides into narrow valleys, roadside ditches, culverts and low drives.
Frost depth is commonly about 36 inches on the valley side, set by each municipality. In the mountains it runs 36 to 42 inches, with the deeper figures there. That is a footing depth set by the building official.
Materials Delivered in Lycoming County
2A modified is the standard Pennsylvania base stone. It is crushed stone with the fines left in, so it compacts hard under a drive, a parking pad, a shed pad or a patio base. Locally it is also called modified stone.
The same bed of material gets called crusher run when the fines are mixed in. Pennsylvania buyers usually ask for 2A modified for that job. Order it as 2A Modified or Crusher Run.
Clean stone covers the wet spots. #67 Stone and Drain Rock handle drainage and downspout runs. Fill Dirt raises grade and backfills before a base or topsoil goes down. Washed Sand beds pavers and slabs, and Shredded Mulch holds moisture in beds through summer.
Delivery Across Lycoming County
Start by deciding whether you want tons or yards. Then size the load with the calculator so the truck shows up with the right amount. A dump truck then delivers to the site, and you pick your delivery date at checkout.
Coverage runs across the county. Deliveries go to Williamsport, Montoursville, Jersey Shore, Muncy and Hughesville, and out to Montgomery, Cogan Station, Lairdsville, Linden and Trout Run. Mountain addresses at Cammal, Cedar Run, Jersey Mills and Slate Run are on the route too.
Steep valley sides matter for placement. On the ridge side, runoff scours roadside ditches, culvert outlets and gravel drives, and stream banks cut back during heavy rain and snowmelt. Up north, runoff off steep slopes gullies gravel roads and ditches, and rain on snow can set off debris slides.
Choosing the Right Material
Neighboring counties to the north sit on different ground. Bradford, Tioga and Sullivan counties are all in the Glaciated northeast and northwest zone. Glacial deposits over shale, siltstone and sandstone leave stony till on the uplands, often with a dense, slow-draining layer not far below the surface, plus sand and gravel in many valleys.
That slow-draining layer changes the call. On that ground, drainage stone under a drive does more work than it does in a limestone valley here, because water sits higher in the profile. Buyers there lean harder on 2B or #57 for a drainage layer before any base goes down.
Lycoming County has no such layer. Thin stony soils over folded bedrock drain faster on slopes, so the base depth and compaction do the work instead. In the mountain zone, slope protection matters more than underdrain, which is where rip rap and larger clean stone earn their place.
