POUR IT RIGHT, ORDER IT ONCE, KEEP THE RECORD.
Plumb Concrete Pro is a focused concrete and masonry calculator — size the
pour, count the bags, lay out the steel, and keep every number with the job.
No paper pad, no second app, no account.
SIZE THE POUR
• Yardage — slabs, footings, and piers/columns in feet and inches give cubic
yards and 80 lb bag counts, with an optional overage %.
• Bag vs. bulk — turn cubic yards into pre-mix bag counts and pallet loads for
40, 50, 60, or 80 lb bags, with a nudge toward ready-mix on the big pours.
• Base & gravel — the sub-base under a slab in cubic yards and tons.
LAY OUT THE STEEL & BLOCK
• Reinforcement — a rebar grid at 12", 16", or 24" on center gives total linear
feet and the number of 20 ft sticks with the lap splice folded in, for #3–#6
bar; or size welded-wire mesh sheets for the area.
• Masonry — net wall area gives block or brick counts, mortar bags, sand, and
grout for filled cells.
FINISH THE DETAILS
• Slope & drop — the total fall across a run at your pitch, for flatwork
drainage.
• Control joints — max joint spacing and cut depth from the slab thickness.
• Mix order — build a ready-mix spec (strength, slump, aggregate, air, admix,
fiber) as one clean line to text the supplier.
KEEP THE JOB
• Every takeoff saves to an on-device job ledger — search it, pin it, reopen it.
• Roll the saved pours into a project cubic-yard total, and text the order
straight to your supplier.
• Export a clean, branded PDF or PNG, or a .plumb backup, when you choose to.
• English and Spanish, in the app and in the exports.

A note on accuracy: these are fast field estimates, not an engineering or code
determination. Confirm structural, mix-design, nailing, and safety-critical
numbers with your engineer, your supplier, and current local code.
