You can order concrete in Calgary from as little as roughly 1 m³ for a small trench up to a single pour of 90 m³ for a large footing, and everything in between. The load you need depends on the volume of your form, not the size of the supplier. When you own the trucks and the cement, both orders are normal work in the same week.
Most people asking this fall into one of two camps: you have a small job and worry nobody will show up for it, or a big job and worry the supply will not keep pace. Both worries are fair. Here is how it actually works.
1. What counts as a small load, and will anyone deliver it?
A “small load” usually means anything under a full truck. A standard mixer truck in this market carries a limited number of cubic metres, so a 1 m³ trench fill, a set of steps, or a small pad is a fraction of one load.
Plenty of suppliers quietly discourage these jobs, because a truck tied up for a tiny order is a truck not on a bigger one. That is a scheduling problem for them, not a rule of physics. We run our own fleet of mixer trucks and our own cement supply, so a small residential order and a large commercial round are both just entries on the same dispatch board. If a supplier tells you your job is “too small,” it usually means it does not fit their preferred route that day. Ask a second supplier.
2. The short-load reality: minimum charges are normal, so validate them
Here is the part nobody explains cleanly. When you order less than a full truck, most suppliers apply a minimum charge or a short-load fee. That is not a scam. A truck, a driver, and a load of cement cost roughly the same to send whether it carries 1 m³ or a full load, so a floor on small orders is how the economics stay honest.
What varies is the size of that fee, and it moves in market bands. So do not accept a number on faith and do not assume you are being singled out. Do this instead:
- Ask two or three suppliers for the short-load or minimum charge on your exact volume.
- Confirm whether the fee is flat or scales with how far under a full load you are.
- Ask whether the quoted volume is what you pay for or what you receive.
When the answers land in the same range, you are looking at the market, not a markup. When one is wildly out of step, you have found your question for them.
3. Metering to the exact yard, so you do not over-order
The oldest waste in concrete is the leftover. Order too little and you are chasing a second truck mid-pour. Order too much and you are paying to haul away hardened material you never used.
Because we batch from our own plant with our own cement, we can meter production to the volume your job actually needs rather than rounding you up to a tidy truckload. You order the yardage your forms call for, we supply it, and the goal is that you are not paying for material that ends up in a washout pile. That is why “how much do I order?” is worth a real conversation before the truck rolls, not after. For anything beyond a simple slab, have your contractor or forming crew confirm the volume, because a small error in form depth multiplies fast across a footing.
4. Big pours: how capacity actually scales
At the other end, a large footing or wall is not one truck, it is a coordinated round of them. A 90 m³ footing is delivered as a sequence of loads timed so the pour never stalls and the concrete stays within its working window. Walls in the 40 to 60 m³ range work the same way, staged as multi-truck rounds.
The thing that makes this reliable is not luck, it is owning the inputs. Our batch plant runs two cement silos fed by near-daily bulk deliveries, so a big morning does not drain us before the afternoon jobs. In a recent ten-day window our crews batched, delivered, and placed more than 1,100 m³ across roughly 80 separate pours, including single pours up to 90 m³ and Saturday work. That is the difference between a supplier and a broker: a broker sells you someone else’s schedule.
5. What you are actually buying: the right mix, not just the right volume
Volume is only half the order. The other half is the mix, and in Calgary the mix is not optional.
Our standard workhorse for foundations and structural work is a 32 MPa, Type 50 concrete (Type 50 is the sulphate-resistant cement, written as Type HS in current CSA nomenclature) at 5 to 8 percent air, because Alberta’s sulphate-bearing soils and freeze-thaw cycles punish anything less. Municipal and utility work such as thrust blocks steps up to 35 MPa Type 50. For exterior flatwork that gets salted, driveways, sidewalks, and steps, the correct target is CSA exposure class C-2: 32 MPa at 28 days, 5 to 8 percent air, and a water-to-cementing ratio at or below 0.45. For backfilling voids, trenches, and abandoned utilities, a 5 MPa flowable fill-crete self-levels and stays excavatable later.
You do not need to memorize this. You need a supplier who asks what the concrete is for before quoting a price, and who can tell you why your driveway mix and your footing mix are not the same thing.
Proof from a recent ten-day stretch
In ten working days across residential, commercial, municipal, institutional, and industrial sites, our crews:
- Batched, delivered, and placed over 1,100 m³ of concrete.
- Ran roughly 80 separate pours, including Saturday work.
- Delivered footings from 14 to 90 m³ and walls from 40 to 60 m³, staged as multi-truck rounds.
- Placed fill-crete up to 70 m³ on commercial work and around 25 m³ for builder void-fill.
- Started pours as early as 5:00 am and ran evening pours to 5 pm, including a roughly 1,500 sq ft garage slab on a Saturday.
- Ran a five-truck ready-mix fleet and a batch plant with two cement silos fed by near-daily 28 to 42 tonne bulker deliveries.
- Accommodated builders’ concrete testers on site.
Same week, same fleet, from a 1 m³ trench to a 90 m³ pour.
Wondering what a busy concrete operation actually looks like behind the scenes? From residential garage slabs and backyard pads to commercial footings, municipal work, void-fill, and large multi-truck structural pours, our breakdown of A Week of Calgary Concrete: 50+ Pours, Every Job Type, Decoded explains how different projects are scheduled, supplied, and coordinated across Calgary in the same working week.
Who this serves
- Homeowners planning a driveway, garage pad, steps, or a small footing who need a straight answer on minimums and mix.
- Renovators and concrete subcontractors who need same-week supply across scattered small jobs.
- Production home builders and land developers running footings, walls, and void-fill across communities like Mahogany, Seton, Legacy, Rockland Park, Cornerstone, and out to Cochrane, Chestermere, Strathmore, and Okotoks.
- Commercial, municipal, and institutional sites needing coordinated large pours and specified mixes.
Ordering the correct concrete is about more than cubic metres. The mix design, durability requirements, and exposure class all affect long-term performance. For readers wanting a deeper understanding of industry standards, the American Concrete Institute (ACI) publishes guidance on concrete materials, proportioning, and construction practices, while the National Ready Mixed Concrete Association (NRMCA) provides educational resources on ordering ready-mixed concrete, estimating quantities, and quality control. Together, these references help explain why selecting the right specification is just as important as ordering the right volume.
FAQ
What is the smallest amount of concrete I can order in Calgary? Most suppliers will deliver small volumes down to roughly 1 m³, but orders under a full truck typically carry a short-load or minimum charge. The concrete itself is not the constraint; the truck, driver, and trip are. Confirm the minimum with the supplier for your exact volume before booking.
Why is there a minimum charge or short-load fee? Sending a truck costs roughly the same whether it carries 1 m³ or a full load, so a minimum charge keeps small deliveries viable. It is standard across the market. What varies is the size of the fee, so it is worth comparing two or three suppliers to confirm the number is in the normal band.
What is the largest single pour you can deliver? We have delivered single pours up to 90 m³, staged as a coordinated round of trucks timed so the pour does not stall. Larger volumes are handled the same way, as sequenced loads. Owning our own batch plant with two cement silos is what lets big and small jobs run in the same week.
How do I avoid over-ordering and paying for leftover concrete? Have your contractor or forming crew confirm the volume your forms actually need, then order to that number. Because we batch from our own plant, we can meter production to your required yardage rather than rounding up to a full truckload, which reduces leftover you would otherwise pay to haul away.
What concrete mix do I need for a Calgary driveway or foundation? Foundations and structural work generally use 32 MPa, Type 50 (sulphate-resistant) concrete at 5 to 8 percent air for Alberta’s soils and freeze-thaw. Salted exterior flatwork such as driveways should meet CSA exposure class C-2. Tell the supplier what the concrete is for and let them confirm the correct spec.
Can you deliver small and large orders in the same week? Yes. In a recent ten-day stretch our crews placed over 1,100 m³ across roughly 80 pours, ranging from small void-fill loads to a 90 m³ footing. Running our own fleet and cement supply is what makes both order sizes routine rather than a favour.
