1) Measure your area

If you have a complicated shape, don’t worry, give us a call.  We will help you get the right amount for the job.

2) Enter in the measurements

You will need to have your measurements in feet and the depth (height) you want in inches.  The standard for mulch is 3″.

How to do the math:  

One (1) cubic yard covers 100 square feet (10′ by 10′) at a 3-inch depth

Length x Width = Square Feet

Square Feet divided by 108 = Cubic Yards needed for a 3″ depth
Square Feet divided by 81 = Cubic Yards needed for a 4″ depth
Square Feet divided by 54 = Cubic Yards needed for a 6″ depth

** Multiply the cubic yards by 1.5 to get the tons needed for River Rock
