Terms of Use

By using Build Calculators (build.runkodo.com) you agree to these terms. If you do not agree, please do not use the site.

Results are estimates

The calculators give planning estimates based on the dimensions you enter and on typical values for bag yields, material densities and depths, described on the about page. Real materials, site conditions and products vary. Confirm quantities with your supplier before you order, and add a sensible allowance for waste.

Not professional advice

Nothing on this site is engineering, structural, legal or other professional advice. Thickness, reinforcement, footing and depth figures are general guidance, not a design. Your local building code, permit requirements and a qualified professional take precedence, especially for structural work, footings below the frost line and anything that carries vehicles or people.

No warranty

The site is provided "as is" and "as available", without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose and uninterrupted availability. We may change, correct or remove any calculator or content at any time.

Limitation of liability

To the fullest extent permitted by law, we are not liable for any loss or damage arising from your use of the site or reliance on its results, including the cost of ordering too much or too little material, project delays, or defects in work you carry out.

Advertising and third-party sites

The site shows ads served by Google AdSense and may link to other websites. We do not control and are not responsible for third-party ads, sites or their content. How advertising cookies are used is explained in the privacy policy.

Acceptable use

You may use the calculators freely for personal and commercial projects. Do not scrape the site at a rate that disrupts it, attempt to interfere with its operation, or republish its content as your own.

Changes to these terms

We may update these terms from time to time. The date at the top of this page shows the latest version; continued use of the site means you accept it.
