EXAMPLE: You have an area next to your house that you would like to landscape with Washed Stone. That area is 4'-0" wide and 46'-0" long. You estimate that you would like it to be about 4" deep. Your formula would look like:​

4 x 46 x .3333 = 61.2761.27 divided by 27 = 2.27 rounded up to the nearest half yard would be 2.5.

You would order or pick up 2 1/2 Cubic Yards of Washed Stone.


If one of your dimensions happens to be in inches the following table will show you the decimal equivalent to inches.

​1 inch = .083 / 2 inches = .167 / 3 inches = .25 /

4 inches = .333 / 5 inches = .4167 / 6 inches = .5 /

7 inches = .583 / 8 inches = .667 / 9 inches = .75 /

​10 inches = .8333 / 11 inches = .9167 /

​12 inches = 1.0

FAQs and HELPFUL WEBSITES

HOW MUCH MATERIAL DO I NEED?

​How much stone/road gravel/granite do I need? Well, the easiest way to go about this is by giving us a call! We're always happy to give you quick, accurate estimate or...You can use the following formula for squares and rectangles. Length x Width x Height = Cubic Feet and to find the yardage. Divide your Cubic Feet by 27 (the amount of cubic feet in a cubic yard) and this will give you the amount of material you'll need. See example below. One thing to consider when you are ordering gravel granite or topsoil is that you lose some volume due to compaction. For example, if you want your driveway to be 6" thick after compaction with a roller or machine you should add approximately 30% to you order's volume. Stone will not compact, so the measurements are true.




















​WHAT IS THE BEST MATERIAL TO USE FOR MY DRIVEWAY?

​​There are three types of material that we would recommend.  Your choice is going to be dependant upon your personal aesthetic tastes and your budget.Red Granite - Also known as Decomposed Granite or Rotten Granite. The color of our granite is reddish-brown. It is often preferred over road gravel for aesthetic reasons. It begins in the form of granite rock and then decomposes or breaks into a smaller particles or gravel. The Red Granite is then screened to remove any large chunks and to create a consistent blend of stone and clay. It can be used for driveways and pathways and it compacts nicely.Road Gravel - Also know as Dense Graded Base Course or Traffic Bond, 3/4" Road Gravel is the most commonly used product for the construction of driveways and private roads.  It's designed to contain a variety of aggregate sizes in specific quantities that insure that the aggregates work to lock together and it packs quite well.  It's a good road material to be used where a firm base has already been established and it's the most economical of the three choices. Recycled Asphalt - It is asphalt pavement that has been ground into gravel. The Recycled Asphalt product has much of the original oils still in it and with summer heat and compaction the oils and binders are melted into the gravel to make a more permanent and less dusty driveway than traditional Road Gravel. Many choose the Recycled Asphalt as a less expensive alternative to a new, conventional hot mix asphalt driveway.  Recycled Asphalt can come in several grades, the highest being made almost entirely of asphalt, and the lower grades being blends that include recycled concrete, bricks and virgin material. The cost varies according to grade.

CAN THE TRUCK SPREAD THE GRAVEL/GRANITE IN MY DRIVEWAY?

Yes, our trucks can spread material on your driveway, but low hanging tree branches, eaves or electrical/phone wires may impede our trucks. You can count on doing some additional spreading by hand once the truck places the gravel.

EXAMPLE: You just purchased an above ground swimming pool and the manufacturer recommends that it be set upon a base of sand free from stones. You will need to lay down a pad of Mason Sand.  Your swimming pool is 36 feet across and you estimate that you would like the pad to be about 5" deep. You would probably want the pad to extend a little beyond the edge of the pool so we are going to figure for a pad 39'-0" across. Your formula would look like:

39÷2 = 19.5 the Radius (19'-6" converted into a decimal)19.5 x 19.5 = 380.25 the Radius Squared

380.25 x .4167 (the Height) = 158.45

158.45 x 3.14 = 497.53 (Cubic Feet)

497.53 divided by 27 =18.43 rounded up to the nearest yard would be 19.

You would order 19 Cubic Yards of Mason Sand.

You would take the Radius (which is measured from the outside perimeter of the circle to the center) and square it (multiply it by itself).Then Multiply the Squared Radius by the Height/depth (don't forget to convert your measurement into a decimal if your measurements are in inches).Take that calculation and Multiply it by 3.14 (p).
​Divide your results by 27 and you will have the quantity of cubic yards you'll need.
