Bulk Aggregates for Patios in Falls Church, VA

Virginia Rock Supply handles gravel and aggregate delivery in Falls Church, VA for two kinds of buyers. Contractors order 21A by the load for base work, and homeowners order a few tons to finish a patio or walk. Clay ground here drains slowly, so what you put under the pavers matters as much as the pavers.

Our yard serves the independent city of Falls Church, which is not part of any county, along with the Northern Virginia Piedmont around it.

Materials for Falls Church Projects

Most patio work here starts with 21A. It is the standard Virginia driveway base. Compact it in lifts and it will not shift under a paver patio or a shed pad. It is also the right call for a driveway apron that meets a new patio.

Bedding is what keeps a Falls Church patio flat. Screenings, also called stone dust, go down an inch at a time under pavers and flagstone. The fines let you screed a flat, true plane, and they lock the units so joints stay put. For a joint or tight pipe bedding, 89 stone works where screenings would wash or stay too soft.

Drainage behind and under the hardscape needs clean, washed stone. Use #57 Stone in French drains and drywells, and #8 Crushed Stone for finer drainage and pipe bedding. Where a wall needs a free-draining backfill, Drain Rock handles the volume.

Ground and Conditions in Falls Church

Patios in Falls Church most often go wrong at the base, when too little stone goes down. A patio set on a thin layer of stone over clay will heave and settle within a couple of seasons. The pavers stay flat at first, then a corner drops and water pools in the low spot.

The fix is depth and compaction. Excavate deep enough that you can place 21A in lifts and compact each one before the next goes down. Aim for a finished base that holds a screed line without flexing. Then bed the pavers in screenings and keep the whole platform above the surrounding grade.

Clay takes in water slowly, so a summer thunderstorm or the remnants of a tropical system runs off fast. That is why drainage stone and a positive slope away from the patio matter as much as the base.

Winter adds a second problem. Frequent swings above and below freezing drive freeze-thaw heave in gravel and base, with frost depth set by each locality rather than one figure statewide. Saturated clay after a thaw will also rut under a loaded truck, so plan base and driveway work around the working season.

Delivery to Falls Church and the Surrounding Area

Order online and pick the material and the quantity. Decide whether you want to buy by the ton or by the cubic yard, because the two are not the same thing. A ton of dry 21A and a ton of damp screenings take up different volumes, so match the unit to how you measured the job.

To estimate quantity, work out the square footage and the compacted depth you need. Base material compacts, so order a little more than the loose volume you calculate. If you are unsure, use the calculator on the product page and it will convert area and depth into tons or yards for you.

Bulk delivery arrives as a dump load placed where the truck can reach. Think about where you want the pile before the driver gets there, and keep the path clear for a loaded vehicle.

Questions We Hear From Falls Church Buyers

What gravel is best for a driveway in Falls Church?

Start with 21A. It is the Virginia driveway base, and it handles the clay ground here better than a clean stone that will not lock. Top it with Driveway Gravel if you want a finished surface, and keep a drainage stone such as #57 stone along the edges where water collects.

How much material will my project need?

Measure the area and decide the compacted depth, then convert that volume to tons or cubic yards. Base material settles, so add a little extra rather than ordering exactly what the math gives you. The calculator on each product page does the conversion for you, and you can enter your own figures to check the number before you order.

Get Your Patio Base Right the First Time
