How Much Class A Rip Rap (5–10″) Do I Need?
Calculator assumes Class A Rip Rap covers approximately 20 cubic feet per ton. For 5–10 inch rip rap, a 12-inch layer is a practical starting point for most coverage estimates. Coverage may vary based on stone size, stone gradation, placement method, void space, slope, surface conditions, and material characteristics.
Depth under 12″ was adjusted to 12″ for estimating purposes.
Sales tax varies by county and is added at checkout.
Truck delivery count is an estimate based on approximately 20 tons per delivery. Final load count may vary based on material type, truck capacity, legal weight limits, loading conditions, and scheduling.
About Class A Rip Rap (5”–10”)
Class A Rip Rap is a large crushed granite rock consisting primarily of stones ranging from approximately 5 inches to 10 inches in size. Due to quarry processing and natural variation, individual pieces may be smaller or larger than the stated size range.
The large stone size creates open spaces between rocks and allows water to move through the material. Unlike compactable aggregates, rip rap remains a coarse rock layer after placement.
Class A Rip Rap is commonly used in erosion control, drainage, shoreline protection, landscaping, and stabilization applications where larger stone is desired.
Stone size, shape, color, and gradation may vary depending on quarry source and material availability.
Common Uses in Upstate South Carolina
Erosion Control Projects
Commonly used in areas where larger stone is needed to help reduce soil movement caused by flowing water.
Drainage Channels and Swales
Used in open drainage areas where water needs to move through and around large stone.
Culvert Inlets and Outlets
Frequently placed around culvert openings, pipe outlets, and drainage discharge points where water flow may occur.
Pond Banks
Commonly used along pond edges where larger stone is desired to help protect exposed soil from erosion.
Creek Banks
Used along creek banks and drainage areas where flowing water may cause soil movement.
Slope Protection
Placed on slopes where larger angular stone is needed to help protect exposed ground from washout.
Stormwater Drainage Areas
Used in stormwater channels, outlet areas, and drainage structures where large stone is specified or preferred.
General Stabilization Projects
Used in soft, wet, or erosion-prone areas where larger stone is needed for stabilization.
Landscaping Applications
Sometimes used in large decorative or naturalized landscape areas where oversized angular stone is preferred.
Coverage & Yield
• Calculator Assumption: Approximately 20 cubic feet per ton.
• Approximate Coverage: About 20 square feet per ton at 12 inches deep.
• Approximate Coverage: About 13 square feet per ton at 18 inches deep.
• Note: Coverage estimates are approximate and may vary based on placement depth, stone size, stone gradation, void space, placement method, slope, surface conditions, and material characteristics.
FAQ
What is Class A Rip Rap?
Class A Rip Rap is a large crushed granite rock consisting primarily of stones ranging from approximately 5” to 10” in size.
What is Rip Rap commonly used for?
Rip Rap is commonly used for erosion control, drainage projects, culvert areas, pond banks, creek banks, slope protection, and landscaping applications.
Does Rip Rap compact?
No. Class A Rip Rap does not compact into a dense surface like Crusher Run. Open spaces between stones are normal, and the material remains a coarse rock layer after placement.
How much area does one ton cover?
One ton of Class A Rip Rap covers approximately 20 square feet at 12 inches deep or 13 square feet at 18 inches deep. Coverage is approximate and may vary based on placement depth, stone size, stone gradation, void space, placement method, slope, surface conditions, and material characteristics.
Is Rip Rap the same as Surge Stone?
No. Rip Rap is generally larger than Surge Stone. Rip Rap typically ranges around 5”–10”, while Surge Stone is generally around 2”–4”.
Is Rip Rap the same as Crusher Run?
No. Crusher Run contains a mixture of stone and fines designed to compact. Rip Rap consists of large stone and does not compact into a dense surface.
Can Rip Rap be used for drainage?
Yes. The open spaces between rip rap stones allow water to move through and around the material. Class A Rip Rap is commonly used in drainage outlets, swales, culvert areas, and stormwater applications where larger stone is needed.
Can Rip Rap be used around ponds and creeks?
Class A Rip Rap is commonly used along pond banks, creek banks, and similar areas where larger stone is desired for erosion protection. Suitability depends on site conditions, water flow, slope, and project requirements.
Does vegetation grow through Rip Rap?
Vegetation may grow between stones over time depending on soil conditions, moisture, and maintenance practices.
Can Class A Rip Rap be tailgate spread?
Tailgate spreading may be available when site conditions allow. Final determination is made by the driver at delivery. Tailgate spreading helps distribute material during unloading, but it does not guarantee a finished, graded, or level surface. Additional machine work, grading, or hand placement may be required.
How much Rip Rap fits in a tri-axle dump truck?
A typical tri-axle load is approximately 20–22 tons, depending on material weight and applicable road-weight restrictions.
Where do you deliver Class A Rip Rap?
Palmetto Sand & Gravel delivers throughout Spartanburg, Greenville, Cherokee, Laurens, and Union Counties in Upstate South Carolina.
Disclaimer
Class A Rip Rap is a natural aggregate product. Stone size, shape, color, texture, moisture content, and gradation may vary by quarry source, load, and material availability. Individual pieces may occasionally be smaller or larger than the typical 5–10 inch size range. Because this material consists of large angular stone with little to no fine material, open spaces between stones are normal. Coverage estimates are approximate and may vary based on placement depth, stone size, stone gradation, void space, placement method, slope, surface conditions, and material characteristics. Class A Rip Rap does not compact into a dense surface like aggregates that contain fines. Quantities are approximate and subject to normal industry tolerances. Product appearance may differ from photographs shown online. Tailgate spreading, when available, is intended to assist with material placement only and does not guarantee a finished, graded, or level surface.
