How do you calculate concrete quantity for your project?
Enter the dimensions for a slab, foundation, wall, column or other pour. The calculator converts the measurements into cubic metres and adds the selected allowance to produce a recommended quantity.
What information helps with concrete delivery in Montreal?
Urban access can affect delivery or pumping. Add useful details about the street, parking, backyard access, pour distance and desired delivery window.
Is a concrete pump required?
Pumping may help when the truck cannot get close to the pour area, when access is through a backyard or when concrete must travel a longer distance from the street. Add those details to the request.
FAQ
How do I calculate the concrete needed for a slab?
Multiply length, width and thickness, then convert the result to cubic metres. The calculator handles that conversion automatically.
How much extra allowance should I include?
A 5% to 10% allowance is often useful for depth variation, waste and site irregularities. You can choose 0%, 5%, 10% or 15%.
Is the result a guaranteed final quantity?
No. The result is an estimate. Actual site conditions, final dimensions and access can affect the amount required.
Can I request concrete delivery in Montreal?
Yes, you can submit a request. BétonDispo checks available options based on the project location, date, quantity and requirements.
