Get in touch
This is a small independent site, so email is the only channel — but every message is read. Please include the page and the figure you are referring to, since most enquiries are about a specific number.
Corrections
If a density, coverage or depth figure looks wrong, tell us. Constants feed every calculation on the site, so a single bad number affects everyone. Include your source if you have one — a supplier spec sheet or a published standard is ideal.
Supplier data
If you run a quarry or yard and your pounds-per-yard figure differs from ours, we would genuinely like it. Regional density data is exactly what makes an estimator like this more accurate.
What we cannot help with
- We do not sell, quote for, or deliver aggregate of any kind.
- We cannot recommend a supplier in your area.
- We cannot advise on a specific build — ask a local landscaper or engineer.
Privacy
