21A Delivery for Burke, VA

Virginia Rock Supply handles gravel and aggregate delivery in Burke, VA, and a typical driveway or pad job here starts with 21A. It is the standard Virginia driveway base. Burke sits on clay-rich Piedmont soil that drains slowly, so the depth under your slab or drive matters more than the surface you see.

Materials for Burke Projects

Most projects here come down to getting the grade and the pad right before anything decorative goes on top. That means fill and sub-base first, then the right base, then the finish layer.

Building up a pad or raising grade

Where a yard sits low or a shed pad has to come up, start with Fill Dirt. It is bulk fill for raising grade and building up a pad before the 21A goes down. Place it in lifts, compact each one, and keep it clear of the top few inches.

Over that fill, 21A is the base that carries the load on a driveway, parking pad, shed floor or patio. Its fines bind it tight under a plate compactor. If you want a mix that drains a little better under the same load, 21B is the coarser, lower-fines option, though it packs less firmly.

Driveways and walkways

For surfacing an existing drive or topping a compacted 21A base, Driveway Gravel gives you a clean running surface. Walkways and garden paths are better served by Walkway Gravel, which is finer and easier underfoot.

Drainage and flatwork

Where water has to move, #57 Stone is the about 3/4 inch washed stone used in French drains, driveway topping and behind retaining walls. Bed pipes and tight joints with #8 Crushed Stone, and set pavers or flagstone on Screenings for a fine, level bed.

Ground and Conditions in Burke

The soil around Burke is mostly clay weathered from Piedmont rock, with a Coastal Plain strip along and east of I-95 where shrink-swell marine clay shows up. Clay takes in water slowly, so summer storms and tropical remnants run off fast, most of all where development has paved the ground.

That runoff is why an under-built base fails here. Water sits on top of tight clay, softens the subgrade, and the gravel above it pumps and ruts. Cut deeper, use a coarse drainage layer where water collects, and compact in lifts.

Winter adds freeze-thaw heave in gravel and base. Frost depth is set by each locality, and Fairfax County uses 24 inches, so base work planned around frozen or saturated ground is usually work that has to be redone. Sediment also washes off bare clay on slopes after heavy storms.

Questions Burke Buyers Ask

What is the best base under pavers in Burke?

Compact 21A is the usual choice, because its fines bind into a hard, stable bed that spreads load without shifting. Build it in lifts and compact each one. Then set the pavers on a thin, level layer of Screenings rather than more 21A, so the joints stay tight and the surface finishes flat.

Do you supply contractors working in Burke?

Yes. Builders, landscapers and excavators working in Burke and across Fairfax County can order 21A, 21B, fill dirt and washed stone by the ton for delivery to a job site. Order online with the material and quantity, add site access notes, and pick a delivery date at checkout.
