Gravel, Stone and Soil for Arlington County, VA

If you need gravel, stone and aggregate delivery in Arlington County, VA, the ground under your project decides most of the order. Virginia Rock Supply delivers bulk loads across the county, and the material most Arlington jobs start with is 21A.

Most ground in this part of the state is clay-rich soil weathered from Piedmont rock, so base depth and drainage matter more than they would on sand.

Materials Delivered in Arlington County

Order by project type. The list below covers what a driveway, a patio or a drain needs, with each material named the way Virginia suppliers and contractors name it.

21A carries the most weight in this county.

For a drive or a pad

Start with 21A at a compacted depth that suits your traffic, then top it with Driveway Gravel if you want a finished surface. Where you want a coarser base that drains a little better, 21B is the alternative.

For a patio, a path or a drain

Use 21A or 21B as the base, screenings for bedding, and #57 stone or drain rock for the drainage layer. A Walkway Gravel surface suits paths that see foot traffic.

Ground Conditions Across Arlington County

Arlington ground is mostly clay-rich soil weathered from Piedmont rock, including sandstone, siltstone and diabase ground in the Culpeper Basin. A Coastal Plain strip runs along and east of I-95, where shrink-swell marine clay shows up.

Clay takes in water slowly. Summer thunderstorms and the remnants of tropical systems run off fast, most of all where development has paved over the ground. That runoff has to go somewhere, and a base built without drainage tends to hold water and fail.

Marine clay swells when wet and shrinks when dry, so it moves under a slab or a drive. An under-built base on that ground will heave, crack and rut within a season or two. Build the base deeper than you think you need, and add a washed stone drainage layer.

Sediment washes off bare clay on building sites and slopes, and stream banks scour after heavy storms. Slopes in marine clay can creep or slip after heavy rain or snow, which is where rip rap earns its place.

Frozen or snow-covered ground in midwinter, and saturated clay after thaws and long wet spells, are what hold base and driveway work up. This part of the state gets frequent winter swings above and below freezing, more snow than most of Virginia outside the mountains, and real freeze-thaw heave in gravel and base. Frost depth is set by each county or city, 24 inches in Fairfax and Prince William counties.

Delivery Across Arlington County

Order online and pick your quantity by the ton or the yard. The site calculator sizes the load once you enter your length, width and depth, so you can match the tonnage to the area instead of guessing.

Bulk delivery means a truck drops the material where you want it. Measure your access first: gate width, overhead branches and where the pile can sit without blocking a neighbor. Place the pile close to the work so you are not moving it twice.

Virginia Rock Supply delivers across Arlington. Order enough for the compacted depth you need, because base material loses volume once it is packed and a short load means a second delivery.

Choosing the Right Material

The right order shifts with the ground next door. Fairfax County, the city of Alexandria and the city of Falls Church all sit in Northern Virginia on the same Piedmont ground zone as Arlington, with clay-rich soil and the same marine clay strip east of I-95. The ground is similar, so the comparison comes down to typical projects.

Fairfax County leans toward larger residential lots, so drives run longer and 21A volume goes up. Alexandria and Falls Church are denser, where a parking pad, a patio base or a drainage run is more common than a long drive. In all three, the base choice is the same: 21A unless you want the coarser 21B, plus a washed stone layer where water sits.
