Concrete Rubble Tons to Cubic Yards Calculator

Convert a concrete rubble tonnage into cubic yards to check capacity, coverage and storage.

Approximate volume

6.67 cu yd

High confidence

About 1.5 short tons per cubic yard for broken concrete; solid concrete is denser, but rubble carries large voids. The inverse of the volume-to-weight figure. Loose material occupies more space than stacked or compacted material.

Conversion factor applied
0.67 cu yd per short tons

Working from a permitted weight back to a volume tells you how much rubble a container will actually take, which is usually far less than its cubic capacity suggests. Skip and dumpster hire agreements state a maximum weight, and heavy demolition waste reaches it while the container still looks half empty. Loading beyond that limit results in a surcharge or a refused collection, so the practical approach on concrete is to work to the weight limit and accept the wasted volume, or to book a container specifically rated for heavy waste.

Add the equipment this sizes

This result is a specification — 6.667 cu yd — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

How much rubble fits in my weight limit?
Convert the permitted weight to volume and you have the usable capacity — commonly a fraction of the container's physical size. Working to that figure avoids the surcharge that comes with discovering it at the weighbridge.
Does reinforcement change the weight?
Steel is denser than concrete, so heavily reinforced demolition is heavier per volume than plain. It also complicates crushing and recycling, and some facilities price reinforced arisings differently.
Is it cheaper to crush on site?
On a large enough job, usually yes, because it removes both haulage and disposal cost and produces usable sub-base. On a small job the plant hire and space requirement outweigh the saving.
