Material calculators for concrete, masonry and tile — with the drawing, the code check, and a ticket you can hand to the supply house.
Cut stringers, grouted cells, trowel ridges, layer sections — drawn to scale and redrawn as you type. Seeing the section is how you catch a mistake before you cut.
Coverage figures tested against manufacturer charts, not lifted from other calculators. Where the standard formula is wrong, we say so and correct it.
Output is a material list you can copy or print — bags, tons, linear feet — sized to what the supplier actually sells.
Everything runs in the browser. No signup, no upload, nothing leaves the phone. Load a page once and it works in the basement.
Seven tools — pours, walls, and everything that comes in a bag
Six tools — layout, lumber and structure
Five tools — board, paint, trim and floor covering
Three tools — what goes on the outside
Two tools — what goes under and inside the pour
One tool — setting out a run
Two tools — air and load
Most material calculators are a form and a number. That is fine until the number is wrong in a way you cannot see — a mosaic that needs a third more grout than geometry says, a bag of premix that lays a quarter of what the estimating guide assumed, a 2×10 stringer with not enough left after notching to hold anyone up.
Every tool here was built by working the numbers out and then checking them against manufacturer data and trade practice. Where those two disagree, the page says which it is using and why. Where a figure is derived rather than sourced, it says that too, and lets you override it.
The output is a material ticket rather than a bare quantity, because what you actually need at 6am is something to hand across a counter.
