What Is Volumetric Concrete? A Kansas City Buyer’s Guide

September 18, 2026

Volumetric concrete is concrete that is measured and mixed at the job site instead of being fully mixed before the delivery truck arrives. A volumetric mixer carries cement, aggregate, water and admixtures separately, then combines them as concrete is needed. For Kansas City contractors and property owners, that means fresher material, precise quantities and greater flexibility during a pour.


This approach is especially useful when you aren't completely certain how many yards a project will consume or when changing job-site conditions require more control.


How Does Volumetric Concrete Work?

Think of a volumetric mixer as a mobile concrete plant.

Instead of filling a drum with finished concrete before leaving a central plant, the truck arrives carrying the individual ingredients. Those materials are proportioned and mixed at the site.


Custom Readi Mix uses volumetric trucks with on-board controls for volume, slump and mix requirements. The company's service explains that its concrete is metered during delivery, allowing customers to receive the amount actually needed rather than relying solely on a preordered estimate.


That difference can solve one of the most common problems with concrete ordering: estimating exactly how much material an irregular or unpredictable project will consume.


Volumetric Concrete vs. Traditional Drum Delivery

Both methods can produce concrete suitable for construction, but the delivery processes are different.

Factor Volumetric Mixing Traditional Drum Delivery
Where mixing occurs At the job site Before/during transport
Quantity flexibility Produce as needed Quantity generally ordered beforehand
Mix timing Starts on site Starts before arrival
Overordering risk Reduced Depends on quantity estimate
Adjustments Greater on-site flexibility More limited after batching

The biggest advantage isn't that one type of concrete is magically stronger. The advantage is control.

With volumetric delivery, crews can better match production to the pace and needs of the job.


Why Does Freshly Mixed Concrete Matter?

Once cement and water are combined, hydration begins. That chemical process eventually causes concrete to harden and develop strength.


This means timing matters.


A volumetric mixer delays the actual production of concrete until the truck reaches the job site. That can be valuable when Kansas City traffic, site preparation, inspections or other construction variables make schedules difficult to predict.

It also means the crew isn't waiting for a pre-mixed load while watching the clock.


Can Volumetric Concrete Reduce Waste?

One of its strongest benefits is quantity control.

Suppose your calculations indicate a project requires approximately 7.5 cubic yards. Real-world conditions may make the final requirement slightly different.


With a conventional predetermined load, ordering too much can leave unused concrete. Ordering too little may require another delivery.


A volumetric mixer can continue producing material until the required placement is complete, subject to the truck's available materials and project requirements.


Custom Readi Mix specifically promotes metered delivery and charging customers according to the concrete used, subject to its stated 3-yard minimum fee.


That makes volumetric concrete particularly attractive for jobs where exact volume is difficult to predict.


What Projects Are Good Candidates?

Volumetric concrete is useful for much more than large commercial construction.


Common Kansas City applications include:

  • Driveways
  • Sidewalks and walkways
  • Patios
  • Garage and shed slabs
  • Foundations and footings
  • Piers
  • Curbs and gutters
  • Utility trench restoration
  • Concrete repairs
  • Contractor flatwork


Custom Readi Mix currently identifies these types of projects among its common applications.


Why Contractors Benefit From Mix Flexibility

Contractors regularly deal with jobs that change after work begins.


A footing may consume more material than calculated. A repair area may be larger after damaged concrete is removed. One portion of a project may have different specifications than another.


Volumetric equipment offers the ability to respond to some of these changes at the job site instead of treating every load as a fixed batch.


Any concrete used for structural work should, of course, conform to the project's approved plans, specifications and applicable requirements. On-site flexibility should never mean improvising structural mix specifications without authorization.


Is Volumetric Concrete Good for Small Projects?

It can be particularly useful for smaller and mid-sized pours because those jobs often suffer most from inaccurate quantity estimates.


Imagine replacing several sections of sidewalk or pouring a backyard patio. Ordering significantly too much concrete creates waste, while ordering too little can interrupt the work.

Metered production helps narrow that gap.


Custom Readi Mix currently states that a 3-yard minimum fee applies to deliveries, so homeowners and contractors should factor that minimum into project planning.


Volumetric Concrete and Kansas City Weather

Kansas City's weather adds another reason to value control.


Hot weather can increase moisture loss and accelerate hardening, while cold conditions require planning to protect concrete and allow proper strength development. ACI's hot-weather guidance notes that temperature, humidity and wind can affect concrete properties and construction operations. Its cold-weather guidance emphasizes preventing early-age freezing and maintaining conditions that support strength development.


Mixing at the site doesn't eliminate weather requirements. Proper placement, finishing, protection and curing are still essential.

What it does provide is a delivery method designed around greater job-site control.

Frequently Asked Questions About Volumetric Concrete

Is volumetric concrete the same as ready mix concrete?

Volumetric equipment produces ready-to-place concrete, but the ingredients are proportioned and mixed at the job site rather than sending a completely batched load from a central plant.


Do I have to know my exact yardage?

You should still estimate your requirements, but volumetric mixing provides greater flexibility when actual usage varies from the estimate.


Can the mix be adjusted on site?

Volumetric equipment can provide mix flexibility, but structural specifications must always be followed.


Is volumetric concrete suitable for driveways?

Yes. Driveways are one of the residential applications served by volumetric concrete delivery.


Is there a minimum order?

Custom Readi Mix currently publishes a 3-yard minimum fee for its deliveries.
