Order Gravel, Stone and Soil in Northampton, PA

If you need gravel and aggregate delivery in Northampton, PA, the ground here shapes what you order. The valleys around town sit on shale or limestone that weathers to clay, and the ridges above them carry thin, stony soil. Clay holds water and moves under a load, so a thin base fails fast. That is why 2A modified is the starting point for most work here. Pennsylvania Rock Supply delivers bulk stone, sand, soil and fill across Northampton County.

Delivery to Northampton and the Surrounding Area

You order online, choose your quantity by the ton or by the yard, and pick a delivery date at checkout. If you are unsure how much material a pad or drive needs, the calculator on the product page sizes the load for you. A dump truck then delivers to your site in Northampton.

We also deliver to Bethlehem, Easton, Hellertown, Nazareth and Bangor, all within Northampton County. Bulk loads need a spot the truck can reach and dump safely. A driveway, a cleared pad or a firm shoulder works well. Tell us where the pile should land so you are not moving material twice.

Materials for Northampton Projects

Most projects here start below the surface. Raising a low corner, building up a shed or garage pad, or leveling a yard before anything goes on top all come down to fill and sub-base. Get that layer right and the finish material lasts. Get it wrong and you are rebuilding in a season.

For raising grade, fill dirt is the first layer. It brings a low spot up to height before a compacted base or topsoil goes down. On top of that, 2A modified is the standard Pennsylvania base stone, crushed stone with the fines left in so it compacts hard. It carries driveways, parking pads and shed bases.

Where water is the problem, the choice changes. 2B stone is clean washed stone with no fines, so water moves through it instead of sitting in the base. It suits French drains, drainage behind retaining walls and drive bases in wet areas. Buyers who ask for #57 stone are describing the same size, and #57 is how that gradation is specified on many jobs.

For the finish layer, driveway gravel surfaces an existing drive or tops a compacted 2A modified base. Around beds and borders, river rock and shredded mulch handle the decorative side, and top soil finishes lawns and beds once the grade is set.

Ground and Conditions in Northampton

The Great Valley and Ridge and Valley ground here is folded bedrock. Long sandstone ridges stand above valleys floored by shale or by limestone and dolomite that weather to clay. Rain and snowmelt run off those steep ridge slopes and collect in the valleys below.

That runoff does two things. It scours roadside ditches, culvert outlets and gravel drives, and it cuts back stream banks during heavy rain and snowmelt. In the limestone and dolomite valleys, water concentrated from roofs, gutters and drives can open sinkholes. That is a limestone valley issue, not something every part of the county shares.

Clay subgrade is the other half of the problem. It holds water, and a base sitting on saturated clay loses its compaction. So the base has to drain as well as carry load, which is why clean stone goes under and behind anything holding back earth.

Timing matters too. 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. Cold winters bring repeated freeze-thaw cycles that heave and break up a thin base or one that holds water, and frost depth here is commonly about 36 inches, set by each municipality.
