Copy this slab snippet
Every calculator page has its own snippet. A concrete slab looks like this: <iframe src="https://construclytic.com/embed/concrete-slab" title="Concrete slab calculator" width="100%" height="720" loading="lazy" style="border:0;max-width:100%"></iframe> Replace concrete-slab with any approved calculator slug from /tools. Width 100% and a height of 640–900px works on phones.
What the embed is allowed to do
It calculates the same reviewed formula as the public page. Users can change units and measurements. They cannot save an account inside the iframe. “Add line” opens the full Construclytic estimate in a new tab.
What it is not
Not a contractor-lead form. Not a supplier price. Not engineering advice. Do not frame Construclytic as a bid, a quote engine for your clients, or a live ready-mix ticker. Keep your own “planning only” line next to the iframe if you sell work from that page.
How to share a takeoff without an iframe
Every calculator URL stores the current measurements in the query string. Copy the address after you type length, width and depth — that link reopens the same numbers. On a phone, use Share on the calculator or on the quote letter.
Directories and reviews
If you list Construclytic, use the live count from the site (113 reviewed calculators), the contact inbox contact@construclytic.com, and the line “A planning tool. Not engineering advice.” Do not invent testimonials. Product questions go to the public inbox.
Video walkthroughs
Screen recordings of the slab takeoff, add-line, and quote/invoice print belong on the owner’s channel when they exist. Until then the live calculator and the How we calculate page are the walkthrough. Do not paste stock footage as a product demo.
