Q: How do I know how much stone I need for a job?


A: Looking to renovate your home or business, but are unsure of where to start? The good news is it is fairly simple to calculate how much product you will need for a job. You will want to first measure your area to get your cubic yards. From there you are able to assess how many tons or pallets you may need for the given area! Check out our project calculator to see how much material you will need.

Q: How many tons are in a yard?


A: in general, 1.33 tons = 1 yard of stone. However this can depend on the exact size and the classification of the stone. For example, granite is a very heavy stone and slate is a very light rock. The composition and density has a huge effect on the weight to volume ratio. 

Q: How many cubic feet are in a cubic yard?


A: there are 27 cubic feet in one cubic yard. Cubic yards are used for measuring the quantity of stone you will need to fill a desired area with the selected stone, mulch or material of choice. 

Q: How much stone should I cover the ground with?


A: We typically suggest a depth of 2-3 inches to cover your area. You want to make sure you get a good amount so there is no sparse areas.


Q: What is the difference between screened and washed stone?

A: Screened stone is ran through a screener to help break up the dirt and mud on the material. When you screen the material it helps to separate size as well as get some of the dirt off. When you wash the material it is screened and ran over with water to get the product extra clean.
