Concrete is ordered by volume, and ordering wrong is one of the most common ways a small job goes sideways. The Gatineau Concrete calculator estimates the volume your slab, footing or pad needs from a few simple measurements, so you walk into a quote already knowing roughly how much concrete the job takes. Confirmed on the site visit, ordered to the actual measure.
Concrete is poured by the cubic yard or cubic metre, and the cost of getting it wrong runs in both directions. Order short and the pour stops mid-job, the cold joint is permanent. Order long and you pay for concrete that runs into the form or hardens in the truck.
The calculator does the math from a few inputs, length, width, thickness, footing diameter, so a homeowner planning a small backyard patio or a contractor sizing a foundation footing can budget the order with confidence.
On the site visit, we confirm the volume with a real measure, account for waste and over-excavation, and place the order against the actual number, not a guess. It is one of the inputs that makes our ready mix supply scheduling predictable.

How to use it
How to Calculate Your Concrete Volume
Measure the area
Measure the length, width and finished thickness of the slab, the diameter and depth of the footing, or the size of the pad. Write them down before you mix or order anything.
Plug into the calculator
Enter the measurements into the calculator. It returns the volume in cubic yards or cubic metres, which is what concrete is ordered in.
Add a small waste allowance
Real-world pours over-run a little, into uneven sub-grade, the form fillet, the wheelbarrow trip back. We usually add a small percentage so the pour finishes without stopping.
Confirm on the site visit
We re-measure on the free estimate, account for the real sub-grade, and order to the confirmed number. The calculator gets you in the ballpark; the on-site measure makes it exact.
From volume to project
What Comes After the Volume Number
Knowing the cubic yardage is one input. The next decisions are budget and finish: pair the calculator with our cost guide for the Gatineau range on that volume, and the concrete types comparison to choose the finish.
Once the slab is in, the care and maintenance guide shows how to keep that volume of concrete looking new through Quebec winters. Together they turn a number into a real project plan.
Measurements, waste allowance, slab vs footing inputs and confirming volume in Gatineau.
It gives a reliable ballpark from clean measurements. The real number is confirmed on the site visit because real sub-grade rarely matches a perfect rectangle, but the calculator gets you in range for budgeting and planning.
For a slab: length, width and finished thickness. For a footing: diameter and depth. For a pad: length, width and depth. The calculator converts those into cubic yards or cubic metres.
Yes, usually a small percentage. Real pours over-run into uneven sub-grade and form fillets, and stopping mid-pour creates a cold joint, so a small waste allowance is cheaper than a short order.
Yes. The calculator handles slabs, footings and pads. For very small jobs like fence posts, bagged Quikrete or Sakrete mixed to the printed ratio is usually the right answer instead of a delivery.
Break it into rectangles or shapes you can measure, calculate each one, and add the volumes together. We confirm the total on the free site visit and place the actual order against the measured number.
