Terms of use & disclaimer

Using the calculators

pourplot's calculators are free to use for personal and commercial planning. You may print, save and share the tickets and links they produce.

Estimates, not engineering

Every result is an estimate for planning and ordering. Quantities depend on your actual site: uneven ground, form sizes, compaction, moisture and waste all change what you need. pourplot does not design structures and does not give engineering, building-code or legal advice. For footings, foundations, walls, piers and anything load-bearing, follow your approved plans, a qualified professional and your local building code.

Prices and published figures

Costs, bag yields and material weights come from manufacturers and published guides, cited on each page and on the methodology page. They can change, and local prices vary. Confirm quantities and prices with your supplier or contractor before you buy.

No warranty

The site and its results are provided "as is", without warranties of any kind. We work to keep them accurate, but we don't guarantee that any result is complete, correct or suitable for your project.

Limitation of liability

To the extent the law allows, pourplot is not liable for any loss or cost arising from using the site or relying on its results, including over- or under-ordered materials, delays or project costs.

Links to other sites

We link to sources and other websites for reference. We don't control them and aren't responsible for their content.
