Bulk Aggregates for Drainage in Merrifield, VA

If you need gravel and aggregate delivery in Merrifield, VA, Virginia Rock Supply stocks the sizes local crews ask for by name. The base of most work here is 21A.

Drainage material matters in Merrifield, which sits on clay-rich Piedmont ground that sheds storm water fast once it is bare or paved.

Materials for Merrifield Projects

Water is the first thing to plan for on most Merrifield jobs. Clay takes in water slowly, so a French drain, drywell or downspout run only works when the stone around it stays open. Washed stone is the answer, because the fines are rinsed out and water moves through the voids.

These are the sizes we send out most, listed from coarsest to finest.

For a driveway, 21A goes down first as the compacted base, then a clean stone on top. Driveway Gravel surfaces or tops an existing drive. If you want a base that drains a little better and packs less tightly, 21B is the coarser, lower-fines option.

Around the house, RipRap armors ditch banks, culvert outlets and slopes against storm runoff. River Rock and Large River Rock handle dry creek beds and decorative borders.

Ground and Conditions in Merrifield

Start with the calendar, not the material list. Midwinter ground in Fairfax County is often frozen or snow covered, and saturated clay after a thaw or a long wet spell will not compact. Base and driveway work waits for those windows.

Frost depth here is set by the county and runs 24 inches in Fairfax, which makes freeze-thaw heave a real winter factor in gravel and base. Build the base deep enough and drain it, and you cut the heave you have to fix in spring.

The soil is mostly clay-rich material weathered from Piedmont rock, with shrink-swell marine clay in the Coastal Plain strip along and east of I-95. Marine clay swells when wet and shrinks when dry, so it moves under a slab or a wall footing.

Erosion follows the same story. Sediment washes off bare clay on building sites and slopes, stream banks scour after heavy storms, and slopes in marine clay can creep or slip after heavy rain or snow.

Delivery to Merrifield and the Surrounding Area

Virginia Rock Supply delivers bulk aggregate across Merrifield and Fairfax County, including Centreville, Reston, McLean, Burke and Annandale. Lead time depends on the material and the haul, so plan your pour or your base work around the delivery window rather than the other way round.

You can order online and pick your quantity by the ton or by the cubic yard. Work out what the load is for, then use the calculator to size it. A driveway base, a drain trench and a drywell all take different volumes at different depths.

Bulk delivery means a dump truck that needs a clear, firm place to back in and drop. Soft ground after rain is the usual problem, so keep the truck path off saturated clay. If the site is tight, say so when you order and we can talk through where the pile should land.

Ordering early in the week helps when the forecast turns wet. Material that has to sit on a soft pad is material you may have to move twice.
