Cost Dynamics of “Premix” Concrete: A Detailed Examination
#1
This article explores the pricing of premixed concrete (ready-mix) through real-world examples, regional factors, and best practices to help you make financially informed decisions.

Actual User Experience: A Price Surprise
An operator ordered premix in cubic meters, expecting local pricing around $55 per cubic meter**. That estimate wildly undershot reality—once invoiced, the price was $155/m³ for a one-off order from a recent small-scale mixer. A second quote from a regional supplier (85 km away) offered 8 m³ for just $600 total, which equates to $75/m³—less than half the local charge .

Why Such Price Discrepancies?
  • Order Size & Truck Size: Short loads cost more per unit due to inefficiencies in loading and delivery logistics.
  • Local vs. Regional Suppliers: Smaller plants may charge premium rates for convenience or due to lower volumes.
  • Operational Overhead: Local suppliers might price higher to compensate for lower throughput or higher labor and maintenance costs.
  • Transportation & Fuel Costs: Delivery distance and fuel surcharges can quickly raise the final price.

Typical Concrete Pricing in Different Units
  • By Cubic Yard (U.S.): Commonly $110–$180/yard, with averages around $130–$170 depending on region and mix strength. Short-loads and weekend deliveries can add $40–$60 or more per yard .
  • By Cubic Meter (Metric): $55–$155/m³ (roughly $42–$118/yard), based on the real-world case mentioned and typical conversion rates between m³ and yd³.

Cost Structures: Truckload vs. Bagged vs. Volumetric
  • Bagged Mix (DIY): Approximately 45 bags (80 lb each) per cubic yard. At $3.60 per bag = ~$162/yd³. Labor and equipment often make this method impractical beyond very small jobs .
  • Ready-Mix (Transit Trucks): Central batching plants deliver premixed concrete, optimizing mix consistency and reducing jobsite labor. Best for 10+ yd³ projects where base cost ~$119–$147/yd³ and short load fee ~$53/yd³ if under 10 cubic yards .
  • Volumetric (Onsite Mixing): Trucks mix on-site and can charge ~$22–$25/yd³ for the truck, on top of concrete costs. Offers flexibility, useful for small or multi-location projects .

Practical Advice: When to Choose Each Option
  • Small Projects (<4 m³ / <5 yd³): Premix can be surprisingly expensive. Compare with bagged DIY costs or look for volumetric providers nearby.
  • Moderate Sized Orders (4–10 yd³ / 3–8 m³): Expect short-load premiums. Consider shopping wider or consolidating orders.
  • Large Orders (10 yd³+): Best value from standard ready-mix trucks—bulk price drops and no short-load fees.

Lessons Learned & Strategy
  • Always Request Multiple Quotes: Even from nearby suppliers—rates may vary drastically.
  • Bundle Projects When Possible: Larger combined orders reduce per-unit cost.
  • Watch Delivery-Related Fees: Weekend delivery or short loads can raise total price by 20–60%.
  • Evaluate DIY vs. Delivery: For very small volumes, bagged concrete may cost less—if labor and time aren’t a concern.
  • Negotiate with Suppliers: Especially local or smaller operators; better rates may be available for repeat or bulk business.

Glossary of Key Terms
  • Premix / Ready-Mix Concrete: Factory-mixed and delivered to the construction site ready to pour.
  • Short Load Fee: Additional charge per unit if order is smaller than a standard full truck (e.g. under 10 yd³).
  • Volumetric Mixer: Truck that stores ingredients separately and mixes on-site to order size.
  • Mix Design: The engineered proportions of cement, aggregate, water, and additives for a specified concrete strength.
  • PSI (Pounds per Square Inch): Indicates concrete compressive strength; higher PSI concrete costs more.

Summary
The case of $155/m³ premix shows how local convenience can come at a premium. By comparing pricing per cubic meter or yard, evaluating delivery and short-load fees, and considering DIY methods or volumetric suppliers, contractors can make smarter decisions and save significantly on concrete costs.
