Bulk Aggregate Delivery Across Erie County, PA
Pennsylvania Rock Supply handles gravel, stone and aggregate delivery in Erie County, PA. Start with the calculator to size the load, then pick your material. Most base jobs here start with 2A modified, the crushed stone with the fines left in so it compacts hard. Ground across the county is glacial deposits over shale, siltstone and sandstone, and it stays wet in a lot of places.
Materials Delivered in Erie County
Yards around Erie still use the older names, so you will hear 2B for #57 and 1B for #8. Here is how the sizes run, coarsest to finest.
2A modified is the standard Pennsylvania base stone. It carries extra fines, which is why it compacts hard. Locally it is a trade name for a 2A-type base. Order it for driveways, parking pads, and shed or patio bases. If you want the same compacting job under another name, Crusher Run is the one buyers ask for with fines mixed in.
For concrete and masonry work, Washed Sand beds slabs and pavers while Mason Sand goes into brick and block mortar. Top Soil and Garden Soil handle lawns, raised beds and final grading. Fill Dirt raises grade before a base or topsoil goes down.
Ground Conditions Across Erie County
Erie County spans two ground zones, and the working season differs between them. Base work waits for thawed, drained ground and runs into fall. Base stone should not go down on frozen or muddy ground.
In the Lake Erie plain, covering Erie, Harborcreek, North East and Girard, you are on glacial till and old lake and stream deposits of sand and gravel over shale and siltstone, laid out in low ridges running parallel to the lake. Lake-effect snowmelt, spring rain and summer storms feed streams draining north to Lake Erie. Flat ground over dense till can hold water, so plan a clean drainage layer.
In the glaciated northeast and northwest, covering Corry, Edinboro, Union City and Albion, water perches above a dense, slow-draining till layer from fall into late spring. Low spots, drives and footings stay wet, and wetlands are common. That is where 2B stone and #57 stone earn their place behind walls and under shed pads.
Frost depth is commonly about 42 inches in the Lake Erie plain and 36 to 42 inches in the glaciated areas, set by each municipality. Cold winters bring repeated freeze-thaw cycles. Snowmelt keeps a poorly drained base wet, which is when it breaks up.
Erosion runs two ways here. Along the lake, bluff recession affects state-designated hazard areas with building setbacks, and stream banks and ditches scour after heavy rain and snowmelt. Inland, runoff off slow-draining soils cuts roadside ditches, culvert outlets and gravel drives. RipRap and large river rock armor those spots.
Delivery Across Erie County
You order online and size the load by the ton or by the yard using the calculator. Pick your delivery date at checkout, and a dump truck brings the material to the site.
Coverage runs across the county. Erie, Harborcreek, Fairview, Girard, Lake City and North East sit along the lake plain. Corry, Edinboro, Union City, Waterford, Albion, Cranesville, McKean and Wattsburg sit inland. Where the truck can set up matters more than distance, so have the drop spot clear before the date.
Choosing the Right Material
Ground shifts as you cross into neighbouring counties, and the base or drainage choice shifts with it. Crawford County to the south is in Northwestern Pennsylvania and spans the glaciated northeast and northwest plus the North-central high plateau and Allegheny Mountains. Where Crawford shares Erie's glaciated zone, the ground is similar, so the comparison is usually about the project rather than the soil.
Warren County spans the North-central high plateau and Allegheny Mountains plus the glaciated northeast and northwest. Where it shares Erie's glaciated ground, drainage decisions carry over much the same way. Where the plateau and mountain ground takes over, the work tends to be more about slope and runoff control than about a deep compacted base, which favors clean stone and armoring over a fines-heavy base.
Inside Erie County, the split is simpler. Damp low ground over dense till calls for clean stone and a drainage layer. Well-drained ridges and the lake plain take a compacted 2A modified base with a clean stone topping.
