Concrete work can involve serious safety and structural risks. Before you order materials, pour concrete, or build anything, you should consult a qualified engineer, architect or contractor and follow your local building codes, standards and regulations.
3. Calculator Disclaimer
Our calculators produce estimates based on the values you enter and standard formulas and assumptions. Actual quantities and results can differ because of factors such as site conditions, formwork, wastage, spillage, subgrade variation, mix design, weather, measurement errors and local practice.
- We do not guarantee that any result is accurate, complete or suitable for your specific project.
- You are responsible for checking your inputs, verifying the results independently and adding a suitable allowance for waste and safety.
- You use the calculators and rely on their results entirely at your own risk.

7. Advertising
The Website displays advertisements, including ads served by Google AdSense and other third-party advertising partners. We do not control the content of third-party ads, and the presence of an ad does not mean we endorse the advertiser, product or service.

8. Affiliate Links and Sponsored Content
Some pages may contain affiliate links, and we may earn a commission if you purchase through them, at no extra cost to you. Affiliate and sponsored content is disclosed within the relevant content.

The Website may link to or integrate third-party websites, tools and services (for example analytics, ad networks, embedded content).

11. Disclaimer of Warranties
The Website, its calculators and all content are provided on an “as is” and “as available” basis, without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, accuracy, reliability and non-infringement.

To the fullest extent permitted by law, we and our owners, operators, contributors and affiliates will not be liable for any direct, indirect, incidental, consequential, special or punitive damages, or for any loss of profits, data, materials, business or goodwill, arising out of or related to your use of (or inability to use) the Website, its calculators or its content, including any reliance on calculator results, material over-ordering or under-ordering, construction defects, structural failure, property damage, injury or death, even if we have been advised of the possibility of such damages.
If liability cannot be excluded under applicable law, our total liability to you will be limited to the greatest extent the law allows. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.
