Innovation in Action — Sterling Contractors Pours Jointless Freezer Slab Using Internal Cure LFA

In a bold step toward advancing concrete performance, Sterling Contractors of North Webster recently completed a freezer slab pour with the help of SRM Readymix. This project reflects the power of collaboration, innovation, and a shared drive to push the boundaries of what’s possible in durable concrete construction.

Project Overview

The team’s goal was straightforward but ambitious: deliver a high-performance, jointless slab solution suited for freezer applications. Working through the cold winter month of January, Sterling Contractors poured the slab with precision and efficiency—demonstrating how controlled conditions can actually enhance mix behavior and performance.

Why Internal Cure LFA?

The decision to incorporate Internal Cure LFA came from a strategic focus on long-term quality and innovation. The advanced curing approach helped:

• Reduce shrinkage, maintaining dimensional stability
• Eliminate traditional curing methods, streamlining the process
• Replace densifiers, lowering labor costs and simplifying finishing

Together, these factors contributed to a smoother, joint-free surface ideal for low-temperature environments where traditional curing methods can underperform.

Partners and Innovation

This project reflects the power of strong partnerships.
SRM supplied high-quality readymix, ensuring consistency and reliability in every yard poured. Meanwhile, Sterling Contractors demonstrated their commitment to modern construction practices and cutting-edge technology.

“We’ve worked with Sterling Contractors before, and they continue to impress us with their focus on efficiency, performance, and innovation,” one team member noted.

Big credit goes to Sterling for leading the charge with E5 technology, leveraging it to enhance curing chemistry and minimize variation.

Unique Aspects of the Pour

While January may not be a typical choice for a major concrete pour, the consistent cold temperatures proved beneficial. The steady conditions improved chemical synergy within the mix, making this pour a prime example of how controlled environments can yield better results.

E5 Benefits

E5 isn’t just another additive—it’s a performance amplifier. Beyond providing internal curing, E5 improves the efficiency of other mix components, ensuring a denser, more resilient concrete structure. It’s a forward-thinking solution for modern applications that demand precision and durability.

Conclusion

This freezer slab project serves as proof that innovation and collaboration can redefine what’s possible in concrete performance. Thanks again to SRM for their material support and Sterling Contractors for pioneering excellence with LFA and E5 technology.
