2A Modified Delivery for Whitehall, PA

Rain and snowmelt pour off the steep ridge slopes into the Lehigh Valley, and that runoff scours roadside ditches, culvert outlets and gravel drives across Whitehall. Pennsylvania Rock Supply delivers gravel and aggregate in Whitehall, PA to answer it. Start with 2A modified, the crushed stone with the fines left in that compacts hard.

It sets the base for driveways, parking pads and shed floors. Order online and pick your delivery date.

Delivery to Whitehall and the Surrounding Area

Order online and choose your quantity by the ton or yard. Size the load with the calculator built into the product listing, then pick a delivery date at checkout. A dump truck brings the material to your site.

Pennsylvania Rock Supply delivers across Whitehall and Lehigh County, including Allentown, Emmaus, Breinigsville, Catasauqua and Slatington. Bulk loads drop where the truck can reach, so keep the pad, drive or bed clear before it arrives.

Think through the drop before you order. A full load of 2A modified spreads across a driveway or building pad, and where it lands decides how much work follows. Point the driver to firm, dry ground.

Materials for Whitehall Projects

Raising grade and building pads drive most orders here. Fill and sub-base come first, then the surface stone on top. Match the material to the job and the base holds.

Fill and Sub-Base

Start with Fill Dirt to raise grade, fill low spots and backfill before anything else goes down. Once the grade is set, 2A Modified is the standard Pennsylvania base stone. The fines stay in, so it compacts hard under a drive, a parking pad or a shed floor.

For a compacting base or drive material, Crusher Run does the same job, though Pennsylvania buyers usually ask for 2A modified.

Driveways and Walkways

Top a compacted 2A modified base with Driveway Gravel to surface an existing drive. For paths that need a finer, walkable surface, use Walkway Gravel.

Drainage and Decorative Stone

Wet areas need clean stone that water moves through. 2B Stone is the washed 3/4 inch clean stone for French drains, drainage behind retaining walls and shed pads in wet ground. RipRap armors ditch banks, culvert outlets and slopes, sold by R-number with R-4 for ditches and larger sizes for banks.

Ground and Conditions in Whitehall

Whitehall sits in folded bedrock country. Long sandstone ridges rise above valleys floored by shale or by limestone and dolomite that weather to clay. Thin, stony soils cover the slopes, and the anthracite coal fields leave ground broken by old strip mines and waste piles.

That ground punishes an under-built base. Clay holds water, and a thin base over it heaves and breaks apart through repeated freeze-thaw cycles. Frost depth here runs about 36 inches, set by each municipality, so build the base to suit the ground and the season.

In the limestone and dolomite valleys, runoff concentrated from roofs, gutters and drives can open sinkholes. Route water away from the pad instead of letting it pool. Base stone should not go down on frozen, soft or muddy ground, so schedule base, driveway and paver work from spring, once the ground has thawed and dried, into late fall.
