Screenings for Patios in Arrington, VA

Plan gravel and aggregate delivery in Arrington, VA around the working season, not the calendar. Virginia Rock Supply stocks 21A for driveways and pads, and the bedding materials that go under pavers and flatwork. Saturated Piedmont clay after a long wet spell is the usual hold-up here, so order when the ground is workable.

Arrington sits in Nelson County, in the Central and Southside Piedmont. Clay subsoil drains slowly, and a patio base that is too thin shows it fast.

Materials for Arrington Projects

On Nelson County clay, patios and flatwork hold level only as well as the bedding layer under them. A base that is too thin or too soft lets pavers rock, and the joints open. The fix starts with 21A. Then the bedding goes on top.

For bedding, Screenings are the standard choice under pavers and flagstone. Stone screenings, also called stone dust, compact to a tight, level bed and hold a flat surface. For pipe bedding, paver joints and porous backfill behind a wall, #8 Crushed Stone is the finer washed option.

Where the subgrade stays wet, put a drainage layer under the base. Drain Rock handles French drains, drywells and downspout runs in the same heavy clay.

For the flatwork edges and finish, Mason Sand beds brick and block and fills paver joints. Washed Sand is the coarser blend for leveling and bedding. If the patio ties into a path, Walkway Gravel gives a finer, walkable surface.

Ground and Conditions in Arrington

The failure you see on a thin base here is edge settlement. Piedmont clay is heavy, often red, and weathered in place over saprolite, a soft decayed rock layer. It drains slowly, so the base has to carry the load instead of the soil.

Dig out enough depth, compact the subgrade, and put down 21A at the right lift thickness. Add a #57 drainage layer where water sits. That is the difference between a patio that stays flat and one that needs resetting in two seasons.

Bare clay also erodes. Cleared slopes and ditches here lose soil in heavy rain, and the remnants of tropical systems drop a lot of water at once. Surface runoff and puddling are the main problems, so plan where water leaves the pad.

Winter brings repeated freeze-thaw. Nights freeze and days thaw, though less than in Northern Virginia or the mountains. Frost depth is set by each locality, so check the requirement for your site before you set base depth.

Delivery to Arrington and the Surrounding Area

Bulk material is ordered by the ton or by the cubic yard, and the two are not the same. Stone is usually sold by weight. Sand, topsoil and mulch are often easier to picture by volume.

To estimate, measure the area and multiply by the depth you want. A patio bedding layer is thin, so a small depth over a large area still adds up to real tonnage. Round up a little for compaction and spillage.

Virginia Rock Supply delivers bulk loads to sites in Arrington and across Nelson County, including Nellysford, Shipman, Lovingston, Schuyler and Afton. Pick your material, set the quantity, and place the order online.

Questions About Gravel and Bedding in Arrington

What gravel is best for a driveway in Arrington?

21A is the standard Virginia driveway base. It carries a driveway over clay subsoil that drains slowly. Top it with Driveway Gravel to refresh the surface, and use #57 Stone for drainage at the edges where water stands.

How much material will my project need?

Measure the area and multiply by the depth, then convert to tons or yards. Bedding under pavers is thin, but a large patio still takes real tonnage once you add the 21A base below it. Use the calculator to convert your numbers, and round up slightly for compaction.
