Start with 21A. It is the standard Virginia driveway base. Clay ground here needs a base that locks up, and 21A does it.

Materials for Annandale Projects

Most jobs here start with a driveway or a parking pad. Build the base first, then surface it. The base carries the load, so it matters more than what you see on top.

21A is the Virginia driveway base. Spread it, wet it, compact it, and it sets up like concrete. Use it under drives, parking pads, shed floors and patio bases. For a coarser mix that drains a little better but packs less tightly, use 21B.

Once the base is compacted, cap it with Driveway Gravel or 3/4" Crushed Stone. Clean stone sheds water off the surface instead of holding it. For walkways and garden paths, Walkway Gravel gives a finer, walkable surface.

Washed stone handles water. Drop to #8 Crushed Stone for paver joints and porous backfill behind walls.

Sand and soil finish the job. Mason Sand beds brick and block and fills paver joints. Washed Sand levels and beds under slabs. Top Soil rebuilds a lawn over red clay. For beds, use Shredded Mulch.

Ground and Conditions in Annandale

Water drives everything here. Clay takes in water slowly, so summer thunderstorms and tropical remnants run off fast. Where development has paved the ground, that runoff has nowhere to go.

So build for drainage. Excavate deep enough that your 21A base sits above the wet zone, and crown the surface so water leaves. Add a drainage layer of Drain Rock or #57 stone where water collects.

Marine clay near the I-95 corridor swells when wet and shrinks when dry. That movement cracks slabs and heaves pads. Compact in lifts, and keep a clean stone layer between clay and your base.

Erosion follows the same story. Sediment washes off bare clay on slopes, stream banks scour after storms, and marine clay slopes can creep after heavy rain or snow. Arm those spots with RipRap.

Winter sets the schedule. Fairfax County sets frost depth at 24 inches, and freeze-thaw heave in gravel and base is a real factor. Frozen ground in midwinter and saturated clay after a thaw both hold base and driveway work up.

Delivery to Annandale and the Surrounding Area

Bulk material arrives by the truckload, dumped where you want it. Order by the ton or by the cubic yard, whichever your takeoff uses. Measure your area first, then set the depth.

Have the drop spot ready. Clear the driveway, mark sprinkler heads and low wires, and pick a pad that a loaded truck can reach and leave. For a driveway base, plan on thin lifts, compacting each one before the next goes down.
