When it comes to planning a concrete project in Innisfil and across Ontario, one of the biggest decisions you’ll face is choosing ready-mix vs site-mix concrete. Both have their place in construction, but the right choice depends on your project size, budget, timeline, and quality requirements.
At Northcrete Concrete, we understand the importance of this decision - the type of concrete you choose affects not only the cost but also the durability and finish of your project. In this guide, we’ll break down the pros and cons of ready-mix and site-mix concrete so you can make the right call.
Ready-mix concrete is batched at a plant under controlled conditions, then delivered directly to your site by a concrete truck. It’s mixed with precision, ensuring consistent quality every time.
Benefits of Ready-Mix Concrete:
➜ Consistent Quality – Every batch is measured to exact standards.
➜ Time-Saving – Delivered ready to pour, reducing onsite prep time.
➜ Less Waste – Accurate batching means minimal excess.
➜ Durability – Stronger mixes that meet specific project requirements.
➜ Convenience – You don’t need to store raw materials on-site.

Site-mix concrete is mixed manually or with a portable mixer at the job site. The contractor measures raw materials (cement, sand, aggregate, water) and blends them on-site.
Advantages of Site-Mix Concrete:
➜ Potentially Lower Cost (for very small projects).
➜ Control Over Mix Proportions – Can be adjusted on-site.
➜ No Transport Delays – Materials are stored on-site.
Disadvantages of Site-Mix Concrete:
➜ Inconsistent Quality – Human error can lead to weak or unreliable concrete.
➜ Time-Consuming – Requires significant labour for measuring and mixing.
➜ Higher Waste – Extra material often goes unused.
➜ Dust and Noise – Greater environmental impact onsite.

Here’s how the two stack up in terms of cost, quality, and efficiency:
1. Cost
➜ Ready-Mix: Higher upfront cost per cubic meter, but more efficient overall.
➜ Site Mix: It may seem cheaper, but it often leads to higher labour costs and material waste.
2. Quality
➜ Ready-Mix: Produced under strict plant-controlled conditions.
➜ Site Mix: Quality varies depending on the crew's expertise and the consistency of measurements.
3. Speed
Ready-Mix: Delivered ready to pour, cutting hours or days of prep.
Site-Mix: Slows down project timelines with onsite batching.
4. Use Cases
➜ Ready-Mix: Best for residential driveways, commercial floors, foundations, and large-scale projects.
➜ Site Mix: Suitable only for small, low-budget projects or remote areas with limited delivery access.
At Northcrete, most of our clients choose ready-mix concrete because of its:
➜ Reliability – You get exactly what you ordered, every time.
➜ Strength – Engineered mixes for Ontario’s climate.
➜ Efficiency – Faster project completion with fewer delays.
This is especially critical in Ontario, where seasonal temperature changes require concrete mixes that can withstand freeze-thaw cycles.

A homeowner ordered site-mix concrete for a 60m² driveway, thinking it would save money. Unfortunately, poor mixing ratios caused uneven curing and cracks within a year.
The driveway had to be replaced with ready-mix concrete, ultimately costing more.
Moral of the story: Cutting costs upfront can lead to expensive repairs later.

Ask yourself:
➜ Is the project small and non-structural (like a small shed floor)? Site-mix may suffice.
➜ Do you need quality, consistency, and speed? Ready-mix is your best option.
➜ Is your project in Innisfil, Etobicoke or surrounding Ontario communities? Ready-mix is more efficient thanks to local delivery networks.
