Terms and conditions

These terms apply to your use of ConcreteCalculus (https://concretecalculus.com), including every calculator, guide and reference table on the site. ConcreteCalculus is run by an independent developer based in India. By using the site, you agree to these terms. If you don't agree, please don't use it.

Results are estimates

The calculators estimate the amount of concrete for the dimensions you enter, using published manufacturer yields, industry references and the other sources listed on each page. Real pours vary with ground conditions, form work, mixing, settling and waste, so actual quantities can differ from the estimate. Always confirm quantities with your supplier before ordering, and check your measurements before you rely on a result.

Not professional or engineering advice

The site doesn't design or check anything for strength, loads, reinforcement, drainage or code compliance. Notes about minimum thicknesses or post-hole sizes are general guidance from the cited sources, not a design for your project. For footings, foundations, retaining walls, driveways and other structural work, consult a qualified professional and your local building department.

Prices and products

Cost comparisons use only the prices you enter. We don't publish, recommend or guarantee prices, and we don't sell concrete or take orders. Product and brand names in bag-yield tables belong to their owners and are used only to identify where each yield figure comes from. We aren't affiliated with any manufacturer, supplier or retailer.

Using the site

You may use the calculators and content for your own projects, including commercial work such as quoting a job. Please don't:

• copy or republish substantial parts of the site's text, tables or code as your own;
• scrape the site automatically in a way that overloads it or interferes with other visitors;
• try to break, attack or misuse the site or the services it runs on.

Linking to any page and sharing calculator results or share links is always welcome.

Accuracy and availability

We work hard to keep every formula and figure correct, and we fix mistakes when they're reported. Even so, we can't promise that the site is free of errors, that every source is current, or that the site will always be available. Manufacturers change products and data sheets, and we may change, add or remove calculators at any time.

No warranty

The site is provided free of charge, "as is" and "as available", without warranties of any kind, whether express or implied, including warranties of accuracy, fitness for a particular purpose or non-infringement.

Limitation of liability

To the fullest extent the law allows, ConcreteCalculus and the person who runs it are not liable for any loss or damage arising from your use of the site or reliance on its results, including the cost of over- or under-ordering materials, delays, rework or damage to property. Nothing in these terms limits liability that can't be limited by law.

Links and advertising

The site links to manufacturers' data sheets and other external sources, and it may show advertising. We aren't responsible for the content, products or practices of other websites or advertisers. An ad on this site is not an endorsement. How advertising cookies work is explained in our privacy policy.

Governing law

These terms are governed by the laws of India. Any dispute that can't be resolved by contacting us first will be subject to the jurisdiction of the courts of India, unless the law where you live gives you the right to bring a claim there.

Changes to these terms

We may update these terms from time to time. The date below shows the latest version, and continuing to use the site after a change means you accept the updated terms.
