Buy 21A in Catharpin, VA

If you are planning gravel and aggregate delivery in Catharpin, VA, the job usually starts with a driveway, a parking pad, or a shed base. Virginia Rock Supply sells 21A by the ton for exactly that work.

The other half of a driveway job is what sits on top. You build the pad, you dress the surface, and you keep water moving away from both.

Materials for Catharpin Projects

Driveway and base work is the lead here, and the material list splits into four families: base, washed stone, sand, and soil.

Base Materials

21A is the standard Virginia driveway base. Spread it in lifts, water it, and compact until it rings hard. Use 21B under drives and pads where you want a coarser, lower-fines mix that drains a little better but packs less tightly.

On top, driveway gravel surfaces an existing drive or tops a compacted base. For a finer, walkable finish on paths, use walkway gravel.

Washed Stone and Drainage

#57 stone handles drainage, French drains, driveway topping, and concrete aggregate at about 3/4 inch. Many Virginia suppliers simply call it 3/4 inch stone, and 3/4" crushed stone is the same washed size. #8 crushed stone is the finer option for pipe bedding, paver joints, and porous backfill behind walls.

Sand, Soil, and Decorative

Mason sand goes into brick and block work and paver joints. Washed sand levels and beds under slabs. Top soil rebuilds a lawn over clay or thin sandy ground. For beds and borders, river rock and shredded mulch round out an order.

Ground and Conditions in Catharpin

Most of this ground is clay-rich soil weathered from Piedmont rock. Clay takes in water slowly, so a summer thunderstorm or the remnants of a tropical system run off fast. Where development has paved over the ground, that runoff has nowhere to go but downhill and across your drive.

That shapes the build. Cut the base deep enough to reach firm, undisturbed ground, then compact in lifts. Put a drainage layer under and beside the pad so water leaves instead of sitting in the fines. A drive that pumps and ruts after rain is usually a base problem, not a stone problem.

Bare clay on a building site or a slope washes off in heavy rain, and stream banks scour after big storms. Rip rap armors ditch lines, culvert outlets, and slope toes, while drain rock handles French drains, drywells, and downspout runs. In the marine clay strip along and east of I-95, the soil swells when wet and shrinks when dry, so bedding and backfill need to tolerate that movement.

Winter sets the schedule. Prince William County frost depth is 24 inches, and this part of Virginia swings above and below freezing often, so freeze-thaw heave in gravel and base is a real factor. Frozen or snow-covered ground in midwinter, and saturated clay after a thaw, are what hold base and driveway work up. Build before the ground locks or wait for it to drain.

Delivery to Catharpin and the Surrounding Area

Order online and pick your material by the ton. Bulk stone, sand, and soil are sold by weight, so have your square footage and your planned depth ready and the quantity math follows. Bulk delivery arrives by dump truck and is tipped where you want it.

Have the drop zone clear before the truck gets there. Pick a spot on firm, level ground with room for the truck to pull in and out, and keep it away from septic lids, soft turf, and any low spot that will hold water. If the drive is soft from recent rain, say so when you order so the driver can plan the approach.

We deliver throughout Prince William County, including Woodbridge, Gainesville, Triangle, Dumfries, and Haymarket.
