Tons-per-cubic-yard figures are approximate estimating values; actual weight varies with gradation, moisture, and compaction. Don't see a gradation you need? Ask us — we supply all base material and stone gradations.

Estimate your tonnage

Pick a product, enter your dimensions, and we'll estimate the tonnage and truck loads your job needs.

Not sure which product to pick?

Answer two quick questions and we'll point you at the right stone.

Depth is how thick the stone layer will be, not how deep you dig. A gravel drive is usually 4″ of stone; make it 6″ if trucks use it.

Hold the spacebar to pour, and stop on the ticket weight. Mind the stone still in the air — same as the real thing.
