Coverage Calculations

How do I calculate how much tonnage I will need?

The quantity of material needed for coverage can be determined by computing the square footage of the area. Multiply the length of the area by the width of the area to get square footage. 


To determine how many tons of material will be needed first determine depth desired and then divide the square footage of the area based on the coverage chart below.

  

Crushed Granite – 

1 ton of rock will cover approximately:

100 sq. ft. 2" deep

80 sq. ft. 3" deep

60 sq. ft. 4" deep

40 sq. ft. 6" deep

 

Rip Rap –

1"-4" rock will cover approximately:

80 sq. ft. per ton

3"-8" rock will cover approximately:

65 - 75 sq. ft. per ton

Calculating Square Footage

Length x Width = Square Footage 

15 feet x 25 feet = 375 sq feet


To calculate tonnage required for coverage at 2 inches deep, divide the area square footage by 100. 


375 sq. ft./ 100 sq. ft. = 3.75 Tons of material 


To ensure you have enough material for coverage, in this case, we would suggest your order 4 tons of material.

Calculating Square Footage for an L-Shaped Area

This calculation would be done by detemining the square footage of the long and the short sides of the "L" and adding them together.


18 feet x 40 feet = 720 sq feet

10 feet x 40 feet = 400 sq feet


400 sq ft + 720 sq ft = 1, 120 sq feet


To calculate tonnage required for coverage at 2 inches deep, divide the area square footage by 100.


1,1200 sq. ft. / 100 sq. ft. =  11.20 Tons of material


In this case we would suggest your order 11 tons of material.
