1B Stone and Bulk Aggregates for Milroy, PA

Pennsylvania Rock Supply handles gravel and aggregate delivery in Milroy, PA for driveways, drainage and yard work. The base stone buyers here ask for first is 2A modified: crushed stone with the fines left in, so it compacts hard under a drive, a shed pad or a patio. The valleys around Milroy are floored by shale or by limestone and dolomite that weather to clay, and clay holds water.

Materials for Milroy Projects

Water is the problem on most jobs around here. Runoff comes off the ridge slopes and sits in clay, so drainage work needs stone that lets water move instead of trapping it. Clean, washed stone does that. It has no fines, so it will not pack tight and block the flow.

Those are the sizes Milroy buyers use to move water:

• 2B Stone (2B clean stone): washed 3/4 inch crushed stone for French drains, downspout runs, drywells and drainage behind retaining walls.
• #67 Stone: a slightly smaller clean stone for drainage and concrete work where #57 runs coarse.
• Drain Rock: clean stone graded for French drains, downspout runs and drainage behind walls.
• #8 Crushed Stone (1B stone): the small clean chip, about half an inch and down, for walkways and decorative topping.

Work a full base, and the sizes run coarsest to finest. Start with 2A Modified for a driveway, parking pad or shed base. Top it with Driveway Gravel. For bedding under pavers and flagstone, use Screenings, the fine stone dust and chips that pack firm.

Ground and Conditions in Milroy

Timing matters as much as material. 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. On clay valley ground, stone laid over soft subgrade just pumps and sinks.

Cold winters bring repeated freeze-thaw cycles that heave and break up a thin base or one that holds water. Frost depth is commonly about 36 inches here, set by each municipality, so check with your code official on anything structural.

Rain and snowmelt running off steep ridge slopes scours roadside ditches, culvert outlets and gravel drives. Stream banks cut back during heavy rain and snowmelt. In the limestone and dolomite valleys, runoff concentrated from roofs, gutters and drives can open sinkholes, so send roof water and driveway runoff well away from the foundation. Old strip mines and waste piles break up the ground in the coal fields.
