For large contractors running multiple crews who are tired of being at the mercy of ready-mix dispatch schedules
The Ripple Effect of a Late Concrete Delivery
Every experienced contractor has encountered the same frustrating situation at some point during a project. The forms have been built, reinforcement has been tied, equipment is positioned, and the crew is ready to begin pouring concrete. Everything is in place except for one critical piece—the ready-mix truck that was scheduled to arrive at 9:00 a.m.
At 9:15, dispatch explains that the truck is finishing another delivery. At 9:30, it is “on the way.” By 9:45, an entire crew is still standing idle while labor costs continue to accumulate. Whether it is a crew of six, eight, or even ten skilled workers, every minute spent waiting represents lost productivity that cannot be recovered.
What makes situations like this especially frustrating is that the delay often involves a relatively small amount of concrete. A half-yard repair, a small footing, or a few curb sections can bring an otherwise productive day to a standstill simply because the concrete has not yet arrived.
After more than 30 years of working with contractors across North America, we have learned that the biggest challenge is often not the price of the concrete itself. The greater cost usually comes from losing control of the construction schedule.
The Hidden Cost of Depending on Ready-Mix Schedules
Ready-mix producers play an essential role in the construction industry, and they work hard to coordinate thousands of deliveries every year. Their dispatch teams must balance production schedules, truck availability, traffic conditions, weather, and the needs of many different customers at the same time.
Even with careful planning, schedules change. Previous pours take longer than expected, trucks are delayed in traffic, emergency orders arise, or production at the batch plant slows unexpectedly. None of those situations are unusual, but they all affect contractors waiting to place concrete.
The problem is not that ready-mix suppliers are doing something wrong. Their priority is serving multiple customers as efficiently as possible. Contractors, however, have a different priority. They need concrete to be available when their crews are ready to work.
When a scheduled delivery is delayed, the cost extends well beyond the concrete invoice. Labor continues to accumulate while crews wait, equipment sits idle, supervisors spend time adjusting schedules, and work that should have been completed that day often carries over into the next. For contractors managing several crews or multiple jobsites, a delay on one project can quickly affect productivity across the entire operation.
Contractors who only need a small amount of concrete can also find themselves lower on the priority list when ready-mix producers are managing larger, more profitable deliveries. When the plant is busy, a half-yard or one-yard order may have to work around full truckloads and larger pours, which can make scheduling less predictable. In some cases, small-load customers may receive what is commonly referred to as a “hot load”—concrete that has already spent significant time in the truck—or material left over from a larger ready-mix load. Essentially, the contractor may be relying on leftover concrete rather than material produced specifically for that job.
Over the course of a busy construction season, these interruptions can account for hundreds of lost production hours, profit and quality.
Looking at Portable Concrete Production Differently
One of the biggest misconceptions we encounter is that contractors evaluate portable concrete production as simply another piece of equipment to purchase.
In reality, successful contractors often view it very differently.
Rather than asking, “How much does this equipment cost?” they begin asking, “What is it costing our business every time a crew waits on concrete?”
That shift in perspective changes the conversation from purchasing equipment to improving operations.
Portable concrete production is not intended to replace every ready-mix delivery. Large commercial pours and major structural pours will always benefit from traditional ready-mix service. However, for contractors performing frequent small- to medium-sized pours throughout the week, having the ability to produce concrete on demand provides a level of scheduling flexibility that simply is not possible when every load must be coordinated through dispatch.
Instead of planning work around delivery windows, contractors can produce concrete when the project is ready, allowing construction schedules to be driven by jobsite conditions rather than truck availability.
Where Contractors See the Greatest Value
While large commercial pours often justify dedicated ready-mix deliveries, many contractors spend a significant portion of their time completing projects that require only a few yards—or even less than a single yard—of concrete.
These projects commonly include:
- Utility repairs
- Sidewalk and curb replacement
- ADA improvements
- Pole foundations
- Sign bases
- Fence footings
- Equipment pads
- Drainage structures
- Municipal maintenance work
- Small commercial additions
Although these jobs require relatively small quantities of concrete, they still demand the same scheduling coordination as much larger pours.
Many contractors find themselves paying short-load fees, absorbing minimum delivery charges, or ordering more concrete than necessary simply to make a delivery practical.
Producing concrete on-site offers a different approach. Contractors can batch only the amount required for each phase of the project. If additional material is needed, another batch can be mixed immediately. If the project requires less concrete than anticipated, production simply stops.
This process helps reduce waste, eliminates concerns about minimum delivery quantities, and gives contractors a practical way to avoid ready mix minimum charge expenses while maintaining greater control over their schedules.
Building a Multi-Trailer Operation
Many contractors initially assume that portable concrete production is only practical for small repairs or occasional maintenance work.
In practice, a well-organized trailer fleet can support multiple crews throughout the day while maintaining a consistent supply of fresh concrete.

For example, an operation using two Cart-Away MixKing trailer mixers together with an aggregate loading system allows one operator to efficiently load both trailers while crews transport concrete directly to active jobsites.
With MixKing trailer mixers, the operation can realistically produce dozens of yards of fresh concrete during a normal workday. Actual production will vary depending on crew size, travel distances, mix designs, and jobsite conditions.
As workloads grow, adding a third trailer allows additional crews to work independently while increasing overall production capacity. Instead of waiting for scheduled deliveries throughout the day, contractors establish a system that continuously supports ongoing work across multiple projects.
This approach is especially valuable for companies performing utility work, municipal construction, commercial site development, and infrastructure projects where multiple crews may be placing concrete at different locations on the same day.
Expanding Into Portable Batch Plants
As contractor operations continue to grow, some companies reach production levels where centralized batching becomes the next logical step.

A portable concrete batch plant allows contractors to produce larger quantities of concrete while supplying multiple trailer mixers or supporting higher-volume projects directly from the jobsite.
For contractors involved in infrastructure improvements, industrial facilities, utility construction, military projects, or long-term commercial developments, this type of system creates even greater independence from traditional delivery schedules.
Rather than relying exclusively on outside suppliers, contractors gain the ability to manage concrete production according to the needs of their own projects while expanding capacity as their business continues to grow.
A System That Grows With Your Business
One of the patterns we have seen repeatedly over the past three decades is that successful contractors rarely begin with an entire fleet of equipment.
Many start with a single MixKing trailer mixer to solve immediate scheduling challenges. As workloads increase and additional crews are added, they expand their operation by incorporating more trailers, larger loading systems, and eventually portable batching equipment when production demands justify it.
This gradual approach allows contractors to invest as their business grows while building a concrete production system that matches the way they operate.
Because each expansion is driven by actual project demands, contractors gain additional production capacity without fundamentally changing the way they manage their business.
Taking Control of Your Concrete Supply
Construction projects will always involve variables that cannot be controlled. Weather changes unexpectedly, labor availability fluctuates, and field conditions evolve throughout every project.
Concrete availability, however, does not have to remain one of those uncertainties.
At Cart-Away Concrete Systems, we have spent more than 30 years helping contractors produce concrete where and when they need it. Whether your operation is considering a contractor concrete mixer, expanding a concrete mixer trailer fleet, implementing on site concrete mixing, or evaluating a portable concrete batch plant, our goal is to help you gain greater control over one of the most important parts of every concrete project.
When contractors control their own concrete supply, they are able to schedule work according to the needs of their crews and projects rather than the availability of a delivery truck. That operational control helps improve productivity, reduce unnecessary delays, and keep projects moving forward on the contractor’s schedule—not someone else’s.
