Use of the website
You may use GravelScope for lawful personal or commercial planning purposes. You may not intentionally interfere with the website, attempt to bypass security controls, or use automated activity that materially degrades the service.
Estimates, not guarantees
Calculator results are estimates based on the values and assumptions entered. Material density, moisture, grading, compaction, site conditions, supplier practices and measurement error can change the actual amount required.
No professional relationship
Using GravelScope does not create an engineering, construction, landscaping, financial or other professional relationship. For structural, safety-critical or code-regulated work, consult an appropriately qualified professional.
Changes
We may improve the calculator, assumptions, content or these terms over time. Continued use of the website after an update means you accept the then-current terms.
