Roman Stone Begins First EZ-Key® Duct Bank Installation Reinforced with ReforceTech MiniBars™

Construction has begun on the first installation of Roman Stone’s EZ-Key® precast duct bank system as part of an AWS data center development in Kenton, Ohio.

The system is reinforced with ReforceTech MiniBars™, demonstrating how corrosion-free composite reinforcement can support durable, high-performance underground infrastructure for hyperscale data center developments.

The installation also highlights how precast duct bank systems are becoming an increasingly important part of modern data center infrastructure, where construction speed, durability and long-term performance are critical.

Why Precast Duct Banks Matter

Precast duct banks play a critical role in modern data center infrastructure by protecting the underground power and communication networks that keep hyperscale facilities operating.

Compared with cast-in-place construction, precast systems can improve installation efficiency, reduce site disruption and deliver consistent quality through factory-controlled production.

As the demand for AI, cloud computing and hyperscale data centers continues to grow, reliable underground infrastructure has become increasingly important.

Reinforcement for Critical Infrastructure

Underground utility structures are expected to perform for decades under demanding environmental conditions.

Unlike traditional steel reinforcement, corrosion-free composite reinforcement such as ReforceTech MiniBars™ eliminates the risk of reinforcement corrosion while supporting efficient precast manufacturing and durable concrete structures designed for long service life.

For owners and contractors, long-term durability, reduced maintenance and installation efficiency are becoming increasingly important design considerations.

From Engineering to Full-Scale Construction

Moving innovative engineering solutions from laboratory testing into full-scale construction is a critical step for every new technology.

This installation demonstrates how advanced reinforcement solutions can be implemented within established precast production methods and deployed in real-world infrastructure projects.

The project also illustrates how innovation in reinforcement strategy can complement modern precast manufacturing to support efficient construction without compromising structural performance.

Supporting the Next Generation of Data Centers

The rapid expansion of hyperscale data centers is driving demand for infrastructure solutions that combine durability, efficient installation and predictable long-term performance.

Projects such as this demonstrate how precast concrete systems reinforced with advanced composite materials can contribute to the next generation of resilient underground utility infrastructure.

Construction is expected to continue throughout the summer. As hyperscale data center development accelerates worldwide, advanced composite reinforcement is expected to play an increasingly important role in delivering durable, efficient and resilient underground infrastructure.
