3/4 Inch Crushed Stone Delivery for Natural Bridge, VA

How much fill does it take to raise a grade and build a pad that stays put? That is the question gravel and aggregate delivery in Natural Bridge, VA usually starts with. Virginia Rock Supply answers it the same way every time: build the pad first, then cap it with 21A.

Bulk fill, base and drainage material for Rockbridge County jobs has to suit the limestone valley floor country, which shapes how a base needs to be built here.

Materials for Natural Bridge Projects

The pad comes first. If you are raising grade for a shop, a shed or a parking area, Fill Dirt goes down in lifts and gets compacted before anything else. Build it up, water it, pack it, and let the sub-base sit on something solid instead of soft ground.

Once the pad is shaped, cap it with 21A. It is the standard Virginia driveway base, and it is what most Natural Bridge drives, parking pads and shed bases are built on. For a coarser base under drives and pads, 21B drains a little better and packs less tightly than 21A.

For the work around the building, order by what the project needs:

• Driveway base and topping: 21A, then top with Driveway Gravel over the compacted base.
• Patio or walkway base: 21A compacted, then Screenings for a level bedding course under pavers and flagstone.
• Drainage: #57 Stone for French drains and driveway topping, and #8 Crushed Stone for pipe bedding and porous backfill behind walls.
• Lawns and beds: Top Soil over thin or rocky ground, and Shredded Mulch to hold moisture through the summer.

Ground and Conditions in Natural Bridge

Start with the soil, because it decides how much base you actually need. Valley floors here are limestone and dolostone with karst, so bedrock often sits close to the surface and sinkholes and caves occur.

A shallow, uneven subgrade will not carry a pad on its own. That is why the fill layer matters more here than the base thickness in some cases. On ridge slopes the soil is thinner and rockier, so you may hit rock before you hit depth.

Water moves down into the limestone rather than across it, so runoff can open or enlarge a sinkhole and wash soil down into it. Keep drainage away from the pad edge and give the base a path to drain.

Midwinter freezes and snow are the main hold-up, along with soaked ground after thaws and heavy rain. Frost depth is set by each locality, 24 inches in many valley counties and deeper at high elevation, so plan the base depth for the season you are building in.

Delivery to Natural Bridge and the Surrounding Area

Order online and pick your quantity before you check out. Bulk material is sold by the ton or by the cubic yard, and the number you need depends on the area you are covering and the depth you are building to.

For a fill pad, figure the volume first and then convert to tons for the material you chose. If you are unsure, order the base in and adjust the finish grade after compaction rather than guessing high on the first drop.

Virginia Rock Supply delivers bulk loads to Natural Bridge and the rest of Rockbridge County, including Glasgow, Fairfield, Goshen, Natural Bridge Station and Raphine. Have the site clear and accessible for the truck, and spot the pile where you want the material worked from.

Questions Natural Bridge Buyers Ask

What is the best base under pavers in Natural Bridge?

Compacted 21A is the usual choice. Build the 21A in lifts, compact each one, and keep the finished surface flat before the bedding sand goes down.
