Terms and Conditions
Last updated: 5-August-2026
Please read these terms carefully before using www.concreteblockcalculators.com (“the Site”). By using the Site, you agree to them. If you do not agree, please do not use the Site.
1. What we provide
The Site provides free online calculators that produce estimates of construction materials, weights, volumes, and costs. The calculators are informational tools only.
2. Estimates are not professional advice
This is the most important term on this page.
Our calculators do not provide engineering, architectural, construction, or professional advice of any kind. They produce approximate quantities based on standard formulas and industry assumptions, which are published on each calculator page.
You are responsible for verifying every result before acting on it. In particular:
- Confirm all quantities with your material supplier before ordering
- Check your local building codes and permit requirements
- Consult a licensed structural engineer for any structural work, including retaining walls over four feet, foundation slabs, and load-bearing walls
- Follow all applicable fire codes and clearance requirements for fire pits
- Verify actual product dimensions, weights, and yields with the manufacturer, as these vary between suppliers
3. Accuracy and limitations
We work hard to make our formulas correct and to publish the assumptions behind them. However:
- Results are estimates, not guarantees
- Actual material use varies with technique, weather, site conditions, moisture content, and manufacturer
- Block dimensions, core volumes, bag yields, and pallet counts vary between suppliers
- Cost figures are broad regional ranges and will not reflect your local market, site access, or current material prices
- We may change formulas, constants, or features at any time without notice
We do not warrant that the Site or its results will be accurate, complete, uninterrupted, or error-free.
4. Limitation of liability
To the fullest extent permitted by law, ConcreteBlockCalculators and its operators are not liable for any loss or damage arising from your use of the Site or reliance on its results. This includes, without limitation, over-ordering or under-ordering material, project delays, cost overruns, structural failure, property damage, personal injury, or lost profits.
You use the Site and its calculators entirely at your own risk.
5. Acceptable use
You may use our calculators freely for personal and commercial projects — estimating your own jobs, quoting for clients, and planning purchases.
You may not:
- Copy, scrape, reproduce, or republish the Site’s content, formulas, or code without our written permission
- Reverse engineer or extract our calculators for use on another website or in another product
- Use automated systems to access the Site in a way that places unreasonable load on it
- Attempt to interfere with, disrupt, or gain unauthorised access to the Site
- Use the Site for any unlawful purpose
6. Intellectual property
All content on the Site — including text, calculators, code, drawings, layout, and design — is owned by ConcreteBlockCalculators or its licensors and is protected by copyright and other laws.
You are welcome to use calculator results for your own projects and quotes. That does not transfer ownership of the tools or content themselves.
7. External links
The Site may link to third-party websites. We do not control them and are not responsible for their content, accuracy, or practices. Links do not imply endorsement.
8. Availability
We provide the Site free of charge. We may modify, suspend, or discontinue any part of it at any time without notice.
9. Privacy
Our handling of information is described in our Privacy Policy. In summary: the calculators collect nothing, and all calculations run in your browser.
10. Changes to these terms
We may update these terms from time to time. Continued use of the Site after changes means you accept the revised terms. The revision date at the top shows when they were last changed.
