Found an error, spotted a figure that looks off, or want a calculator we have not built yet? We would genuinely like to hear about it — corrections from people who pour concrete for a living are the most useful messages we get.

What we cannot help with
We are not able to give project-specific engineering advice, approve a foundation design, or tell you whether a particular slab will carry a particular load. Those need someone who can see the site and take responsibility for the answer — a local structural engineer or your building control officer.
