Definitions:
L = length (ft)
W = width (ft)
D = depth (ft)
Soils
= L X W X D/27 = Yards
Stone
= L X W X D X 170/2000 = Tons
1” =0.083’ (foot)
Aggregates/Gravel Products
1 ton of compacted aggregate/gravel product will cover:
1” thick = 200 sq ft
2” thick = 100 sq ft
3” thick = 66 sq ft
4” thick = 50 sq ft
5” thick = 40 sq ft
6” thick = 33 sq ft
12” thick = 17 sq ft
Compaction can add up to 25% extra material required.
