Envirocure Big Room System Successfully Delivered to Builders Supply in Fort Payne, Alabama

CDS Group has successfully completed the delivery of a major Envirocure Big Room curing installation for Builders Supply in Fort Payne, Alabama, supporting the commissioning of a new high-capacity concrete block manufacturing facility.

From the earliest design stage, the objective was clear: curing had to be treated as a critical part of production, not simply as a supporting utility. The facility was therefore planned around a purpose-built curing strategy where product handling, chamber construction, insulation, airflow, humidity management, thermal efficiency, and automation operate together as one engineered system.

Working in partnership with Columbia Machine and incorporating the advanced multi-tier rack engineering of HS Anlagentechnik, CDS delivered the complete stand-alone external curing building, including the insulated chamber envelope, PIR wall and roof panels, heavy-duty rack structure, and the full Envirocure Big Room closed-loop curing platform.

The installation was commissioned with full PLC and SCADA integration, ensuring seamless connection to the production line and complete visibility of chamber performance from the first day of operation. This is far more than a curing room – it is a dedicated part of the manufacturing process, designed to improve efficiency, consistency, and plant performance for decades to come.

A Separate Building Designed For Curing

Builders Supply chose to position curing within a dedicated external rack building rather than inside the main production hall. This approach delivers clear operational benefits. By separating curing from the primary manufacturing area, the facility avoids condensation issues, eliminates moisture migration into the main plant, improves product flow, and protects the production hall from unnecessary thermal and environmental exposure.

Products move directly from the Columbia Machine production line into the curing building through a 14-lane arrangement consisting of 13 active lanes and one spare lane, allowing continuous throughput with minimal handling delays.

Supporting this layout is the heavy-duty multi-tier rack system developed with HS Anlagentechnik. The rack structure provides accurate product positioning, robust pallet support, and the structural durability required for continuous high-output production.

The curing building is therefore not simply an enclosure – it forms part of the overall plant strategy and contributes directly to manufacturing efficiency.

Retaining Energy Instead Of Wasting It

The Envirocure Big Room platform operates as a fully enclosed recirculating chamber where temperature, humidity, and airflow work together as one balanced curing environment.

Instead of allowing valuable thermal energy to escape, the system captures and reuses heat generated naturally during cement hydration. This closed-loop approach significantly reduces fuel demand while maintaining ideal curing conditions across the entire chamber. High-volume airflow ensures even heat transfer to every product position, while carefully maintained humidity supports proper hydration and predictable strength development. The result is a curing process that delivers better performance with lower energy input. Key advantages include:

Lowest Possible Energy Consumption,

Closed-Loop Heat Recovery from Cement Hydration,

Stable And Uniform Chamber Temperatures,

Precisely Maintained Relative Humidity,

High-Volume Even Airflow Distribution,

Zero Condensation Within The Curing Building and

Zero Moisture Migration Into The Main Production Hall.

This is efficiency achieved through engineering rather than excess energy consumption.

Better Curing Creates Better Product

Consistent curing conditions have a direct influence on finished concrete quality. Stable temperature and humidity improve early strength development and support stronger long-term product performance. Uniform airflow eliminates hot and cold zones, ensuring that every pallet receives the same curing conditions throughout the cycle. The absence of surface condensation significantly reduces visible efflorescence and improves final product appearance, particularly for architectural products where finish quality is critical.

At the same time, greater consistency across the chamber reduces reject rates, limits unnecessary waste, and improves confidence across every production run. This provides:

Higher Product Consistency,

Improved Early Strength Development,

Better Long-Term Product Performance,

Significant Reduction In Efflorescence,

Lower Reject Rates,

Greater Production Stability,

Better curing improves both product quality and plant profitability.

Visibility Creates Repeatability

A curing system performs best when it can be measured accurately. For this reason, the Builders Supply installation includes a fully integrated Allen-Bradley PLC and SCADA platform, giving operators complete visibility of chamber conditions and system performance in real time.

Temperature, humidity, airflow, burner operation, chamber pressure, alarms, diagnostics, and performance trends are continuously monitored and recorded. This removes uncertainty from daily operation.

Rather than reacting to curing issues after they occur, operators manage a stable process using clear performance data and measurable operating conditions.

This level of visibility improves confidence, simplifies maintenance planning, and supports consistent plant performance over the long term. Curing becomes a managed manufacturing discipline rather than an invisible background process.

Conclusion

The Builders Supply Fort Payne project demonstrates what modern concrete masonry curing should look like when it is engineered correctly from the beginning.

By combining the production integration of Columbia Machine, the structural expertise of HS Anlagentechnik, and the closed-loop technology of CDS Envirocure, the facility has been built around operational resilience, product consistency, and long-term efficiency.

Every element—from the dedicated external rack building to the enclosed curing chamber, airflow design, heat recovery, and full process automation—works together to support better manufacturing outcomes.

The benefits are measurable:

Lower Natural Gas Consumption,

Reduced CO₂ Emissions,

Lowest Possible Energy Usage,

Improved Strength Development,

Significant Reduction In Efflorescence,

Lower Product Rejects,

Reduced Maintenance Requirements,

Long-Term Protection Of Plant Infrastructure and

Greater Process Visibility And Production Confidence.

For producers across Europe and North America, the conversation around curing is changing. It is no longer enough to simply apply heat and/or generate steam while hoping for consistency.

The focus is now on building curing platforms that improve quality, reduce operational cost, support sustainability targets, and protect plant performance over the full life of the facility. Builders Supply Fort Payne is a clear example of that approach already in operation.
