Approximate weight

13.5 short tons

High confidence

About 1.35 short tons per cubic yard for slate chippings; flat plate-like pieces pack differently from rounded stone. A planning figure, not a specification. Confirm the density with your supplier before ordering by weight.

Slate chippings are a decorative surfacing whose flat, plate-like shape distinguishes them from rounded or cubic aggregates. The pieces lie flat and overlap, which gives good coverage per volume and a surface that stays put better than rounded stone. They are laid shallower than most decorative aggregates for that reason — the flat pieces cover well without needing depth, and excessive depth wastes material without improving appearance.

Add the equipment this sizes

This result is a specification — 13.5 short tons — 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 deep should slate chippings go?
Shallower than rounded aggregate, because the flat pieces overlap and cover well. Extra depth adds cost without improving appearance and makes the surface less stable underfoot.
Do slate chippings stay in place?
Better than rounded stone, since flat pieces interlock and lie flat rather than rolling. Edging is still worth having, but migration is less of a problem than with pea gravel.
Why does slate look different when dry?
Because wet slate shows a much deeper colour. Samples are almost always seen wet, so the dry appearance on site can come as a surprise — check a dry sample before committing to a large area.
