RMS Gravel, Inc. is pleased to offer assistance to our customers who are new to the aggregate world and need help with calculating the tons required for a job or need help selecting appropriate aggregate materials for their project. This page has descriptions of each type of aggregate we sell with descriptions of the typical uses of each aggregate. All aggregates are sold in US Tons and we can help calculate the tonnage needed for your project. See the Calculations Section for more information.
Bank Run Gravel
Bank Run Gravel is gravel excavated from the bank or ground and delivered directly to you. It is not crushed material and has not been processed. The aggregates found in bank run are a mix of the native soil and will vary between dig sites depending upn the glacial deposits in which we are excavating. Bank Run is most frequently used as a base layer or filler in driveways and other parking areas because of its lower cost.
Bank Run Gravel weighs approximately 1.5 tons per cubic yard.
Modified Bank Run Gravel
Modified Bank Run Gravel is gravel that has been run through a crusher to break up the larger stones which results in aggregate material with a diameter of 4" and less. Typical uses of Modified Bank Run include top dressing driveways and other parking areas. It can also be used as a base layer in driveways but is a bit more expensive than Bank Run.
Modified Bank Run Gravel weighs approximately 1.5 tons per cubic yard.
Crushed Bank Run Gravel (Item 4)
Crushed Bank Run Gravel is also referred to as Item 4. I has been processed through a crusher to create aggregate material 1 1/2" and smaller. Processing Bank Run through the rock crushers and screening plants results in a more uniform product. It packs well and is often used as a top coat on driveways and other driving/parking areas.
Crushed Bank Run Gravel weighs approximately 1.5 tons per cubic yard.
Surge Stone is produced when crushed gravel is piled from a conveyor belt and the larger (2”-8” diameter) stones roll to the bottom edges of the pile. Surge stone is used for drainage and erosion control by slowing and spreading the flow of water over the ground surface rather than eroding the surface soil. It can be placed in drainage ditches and at the bottom of swales to assist with erosion control.
Surge Stone weighs approximately 1.3 tons per cubic yard.
Washed #2 Stones are processed through a rock crusher and typically measure between 5/8"-1 1/8". #2 Stones can be used in drainage application, septic systems, concrete, and sometimes used in blacktop production. These stones do not pack well so they are not typically recommended as a top coat for driveways but some people use them for back-filling around buildings and in parking areas. The photo to the left is a close-up view of #2 Stones which looks similar to Surge Stone. The Surge Stones are much larger in real life.
Washed #2 Stones weigh approximately 1.3 tons per cubic yard.
Washed #1 Stones are processed through a rock crusher and a wash plant. They typically measure between 5/16"- 5/8" in diameter. #1 Stone is used in concrete and blacktop. It can also be used in french drains, however it is usually mixed the #2 Stones for this application. It is relatively easy to shovel.
Washed #1 Stones weigh approximately 1.3 tons per cubic yard.
Washed #1A Stones have been processed through a rock crusher and a wash plant. Typical sizes of #1A's are between 3/16" and 5/16" diameter. They can be used in septic systems, concrete, and blacktop. It can be used in place of pea gravel, but it is crushed so it will have rough edges rather than the smooth edges of pea gravel. It is easy to shovel making manual labor easier, but it is easily picked up on the soles of shoes so it is generally not recommended for top dressings on driveways or parking areas.
Washed #1A Stones weigh approximately 1.3 tons per cubic yard.
Washed Screen Sand has the finest particle size of our available line of sands. It is often used as a base layer for pool liners and for animal bedding on farms. It is the least expensive of our washed sands.
Washed Screen Sand weighs approximately 1.4 tons per cubic yard.
Washed Mason Sand is more coarse than Washed Screen Sand and is used to mix with mortar when working on masonry projects.
Washed Mason Sand weighs approximately 1.4 tons per cubic yard.
Washed Concrete Sand is more coarse than mason sand and more fine than filter sand. In addition to using concrete sand in mixing concrete it is also suitable for use in sandboxes because it is cleaner than the other sands and is still fine enough to play in.
Washed Concrete Sand weighs approximately 1.4 tons per cubic yard.
Washed Filter Sand has been approved for use in septic systems by the Tompkins County Health Department and the Cortland County Health Department. It is the coarsest of our sands and is most frequently used during construction of private septic systems.
Washed Filter Sand weighs approximately 1.4 tons per cubic yard.
Limestone Crusher Run- RMS Gravel, Inc. has limestone crusher run available for delivery or pick-up. It is typically used as a top coat on driveways. It is low in dust and small particles and packs nicely.
#1 & #2 Stone Mix- RMS Gravel, Inc. is happy to mix any of our products to your specifications. The most comman mix is the 1-2 Stone Mix.

Need help with calculating the tonnage you will need for your project?
The following formulas do NOT take compaction into account for calculating the tonnage required for your project. We recommend adding approximately 10% to your total to ensure you have enough aggregates for your project.
1. Find the Depth Factor
Divide the depth of aggregates in inches by 12
Example: 6" depth / 12 = 0.50
Example: 24" depth / 12 = 2.0
2. Find the Area
For a square or rectangular area: Length (in feet) x Width (in feet)
Example: 12' x 12' = 144 sq. ft.
For a circle: 3.14 x radius (in feet) x radius (in feet)
Example: 24' round pool: 3.14 x 12' x 12' = 452.16 sq. ft.
3. Find the Cubic Yards
[Depth Factor (ft) x Area (sq. ft)] / 27 = Cubic Yards
Example: 12' x 12' square area, 6" deep
(144 sq. ft. x 0.50 ft.) / 27 = 2.67 cubic yards
Example: 24' round pool, 24" deep
(452.16 sq. ft. x 2.0 ft.) / 27 = 33.49 cubic yards
4. Find the Tons
Multiply the cubic yards by the tons per cubic yard for the aggregate material you need
Example: 12' x 12' parking area, #2 stone
2.67 cubic yards x 1.3 ton / cubic yd = 3.47 tons x 1.1 (10% more for compaction) = 3.82 tons
Example: 24' round pool base, washed screen sand
33.49 cubic yards x 1.4 ton / cubic yd = 46.89 ton x 1.1 (10% more for compaction) = 51.58 tons
