Screenings for Patios in Erie, PA

Order gravel and aggregate delivery in Erie, PA the easy way: online, by the ton or yard, dropped at your site. Pennsylvania Rock Supply stocks 2A modified, the base stone this market asks for by name, plus the bedding and drainage stone a patio needs.

Erie sits on the Lake Erie plain, where old lake and stream deposits left sand and gravel over shale and siltstone. That ground drains unevenly, so what you put under a patio matters as much as what you set on top.

Ground and Conditions in Erie

A thin base shows up fast on a paver patio. Edges sink, joints open, and the surface rocks underfoot after a wet spring.

Blame the ground and the weather. Glacial till and old lake deposits sit in low ridges parallel to the lake, and flat ground over dense till holds water. Lake-effect snowmelt and spring rain keep a shallow base wet, and repeated freeze-thaw cycles work it loose.

The fix is a deep, well-compacted base over a drainage layer, not a skim coat of stone. Cold winters here bring a frost depth commonly around 42 inches, set by each municipality, so check with your local building official before you plan flatwork.

Timing matters too. Heavy lake-effect snow pushes base, driveway and paver work to thawed, drained ground in spring and into fall. Never place base stone on frozen or muddy ground.

Materials for Erie Projects

Bedding is the heart of a patio job, and the wrong bedding is why pavers shift. Start with Screenings, also called stone dust. Fine crushed stone under a quarter inch packs firm and holds a level screed bed under pavers and flagstone. A 2A modified base under it sets the structure.

Pair screenings with clean stone where water has to move:

• 2A Modified, the standard Pennsylvania base stone. Crushed stone with the fines left in, so it compacts hard under patios, driveways and shed pads.
• 2B Stone, also called 2B clean stone. Washed stone with no fines, so water passes through; use it in French drains and behind retaining walls.
• #8 Crushed Stone, sold locally as 1B. The small clean chip for walkways and decorative topping.
• Washed Sand, also called concrete sand. Bedding and leveling under pavers and slabs.
• River Rock for dry creek beds and borders that carry runoff away from a patio edge.
