Save this pour to the job
A job list keeps every pour together and totals them into one order - the combined volume, and the bags counted once for the whole job instead of pour by pour. It stays in this browser; there is no account and nothing is uploaded.
Pour sheet · free preview
Your job card, started
This is the real document, built from the numbers you just entered. The free preview runs to the first 2 of its 4 sections. Premium adds the 2 still to come - the bag table with the mixing water each size takes, your mix with its bucket-batching table, and the cure notes - and prints the whole sheet, or saves it as a PDF, with everything else on this page stripped out.

Planning estimate. Bag counts assume the yields listed above - check the yield printed on your bag - and allow extra for over-excavation and spillage. Structural and load-bearing work must follow your local building code and a qualified engineer's specification.

What Premium adds to this pour
Your volume, your bag counts and the start of your pour sheet are above, free, and they stay that way. Everything held back is listed here, in full - there is nothing else.
- The complete printable pour sheet. Free builds the first 2 sections of the real document from your own numbers - what you are pouring, and how much of it, in yards, metres and feet. Premium finishes the job card: the bag count for every size with the mixing water each takes, your mix ratio with a bucket-batching table if you are batching on site, and the cure notes, then prints it or saves it as a PDF with everything else on the page stripped out.
- Cost estimator - put in what your yard charges per bag and per cubic yard, and see bagged versus ready-mix totalled side by side.
- A job list with no limit. Save pour after pour from any calculator and keep them together as one job. Free holds 2 pours so you can see the workspace work; Premium takes the whole job, however many pours it runs to.
- The batch schedule as a document. Your saved pours totalled into one order - the combined volume, the bags to buy counted once against the whole job rather than pour by pour, and the mixes to batch - printed as a one-page schedule for the supplier, or exported as a CSV for your own sheet.
Every calculator, mix-ratio reference, worked-example guide and the rebar estimator stay free forever - full volume, yardage and bag counts included.
