What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone has angular, broken faces, so it locks together and stays put under a load. Natural Pea Gravel is rounded and smooth, which makes it pleasant underfoot but poor at holding a slope or a base. Use crushed sizes like #57 stone or 21A where the material has to carry weight, and Natural Pea Gravel for play areas, walkways and ground cover.

Should I order material by the ton or by the yard?

Both work, and they measure different things. A ton is a weight, and that is how bulk aggregate is sold and hauled. A yard is a volume, and that is what your hole measures out to.

Which stone is best for drainage in Rockbridge County?

It depends on the size of the water. #57 stone is the workhorse for French drains and driveway topping, and #8 crushed stone suits pipe bedding, paver joints and porous backfill behind walls. Where the flow is heavy, #4 crushed stone or Drain Rock moves more water.

Figure the volume before you figure the material. Measure the length and width, decide how deep the lift needs to be, and enter those in the calculator for your cubic yards. From there it is simple: gravel, stone and aggregate delivery in Rockbridge County, VA starts with the right tonnage, and Virginia Rock Supply sells it by the ton. Most drives around here begin with 21A.

Materials Delivered in Rockbridge County

We stock the sizes a Virginia yard actually runs through, from the coarsest base stone down to sand and soil. Here is how the sizes sort out, coarsest to finest, and what each one is good for on a Rockbridge County job.

21A gets ordered the most, and for good reason. For a drive, a parking pad, or a shed base, 21A is the layer that carries the load.

Above the base, the washed sizes do the drainage. Drain Rock handles French drains, drywells and downspout runs, and River Rock covers decorative beds, borders and dry creek beds. For sand, Mason Sand goes into brick and block work and paver joints, while Washed Sand beds and levels under slabs.

Ground Conditions Across Rockbridge County

Timing drives most of the schedule here. Midwinter freezes and snow are the main hold-up, longest up in the higher mountain counties, and soaked ground after a thaw or heavy rain will stop a truck from getting to a soft pad. Plan the base work for a dry stretch and let the ground drain first.

The ground itself splits two ways. The valley floors are limestone and dolostone with karst, so sinkholes and caves occur and bedrock often sits close to the surface. Between those floors run long ridges of folded sedimentary rock with thinner, rockier soil. On the valley floor, that shallow bedrock means you may need to bring grade up with fill before 21A goes down.

Water moves differently in each spot. In limestone ground much of the water goes down into the rock rather than across it, so concentrated runoff can open or enlarge a sinkhole. On ridge slopes, heavy rain and snowmelt run fast into narrow hollows and streams. That is why a drainage layer matters as much as the base: #57 stone, #8 crushed stone and Drain Rock give the water somewhere to go instead of pooling under the pad.

Erosion follows the same pattern. Heavy rain scours stream banks and washes soil off steep, shallow-soiled ridge slopes, and in karst ground runoff can wash soil down into sinkholes and undermine the surface. RipRap on a culvert outlet or a ditch bank holds that ground in place.

Cold is the other factor. Freeze-thaw is regular on the valley floors, and the higher elevations see longer, harder freezes and more snow. Frost depth is set by each county or city, so check the local figure for the site before you set your base depth. Build a solid base in compacted lifts over a firm subgrade at the very least, and go deeper where the ground is soft.

Delivery Across Rockbridge County

Order online and we run bulk loads out across the county. Coverage includes Glasgow, Fairfield, Goshen, Natural Bridge, Natural Bridge Station, Raphine, Rockbridge Baths and Vesuvius, along with the surrounding roads. Lead time depends on the size of the load and the weather, so call the timing early in the week you want to pour or pave.

You can size a load by the ton or by the yard. Tons are how the material is weighed and sold; yards are how the hole measures out. Measure the dimensions and the depth, and the calculator will convert them.

Choosing the Right Material

Ground next door is not your ground, and the base choice shifts with it. Amherst County and Nelson County sit in Central Virginia, on the Central and Southside Piedmont.

Botetourt County, over in the Roanoke Valley, shares our Valley and Ridge ground: limestone and dolostone valley floors with karst, between folded sedimentary ridges. The ground is similar to Rockbridge County's, so compare typical projects instead.
