Contact Us
We welcome questions, corrections, and suggestions. If you spot a density value that looks off, want to request a new material calculator, or have any other feedback, please reach out.
The best way to reach us is by email:hello@calcoul.com
We aim to respond within 1–2 business days. Correction reports (especially those with a cited source for the correct density value) are prioritised.
What to Include
- The calculator or material the question relates to.
- The result you received and what you expected.
- For correction requests: a link to or citation for the reference value.
We do not provide project-specific material advice or act as a supplier. For ordering guidance, please consult your local quarry or landscape supply yard.
