How EZ-Key™ Precast Duct Bank Is Changing the Future of Underground Infrastructure
As demand for data centers, electrical infrastructure, and large-scale development continues to grow, project teams are facing increasing pressure to build faster, more efficiently, and with greater reliability.
Traditional underground utility installation methods often require significant on-site labor, multiple construction steps, and added risks from weather, scheduling challenges, and material coordination. To meet these challenges, Roman Stone developed the EZ-Key™ Precast Duct Bank — an engineered precast solution designed to simplify installation and help infrastructure projects move forward faster.
A Smarter Approach to Precast Duct Bank Installation
A precast duct bank provides a more efficient alternative to traditional cast-in-place construction by moving critical fabrication processes into a controlled manufacturing environment.
Roman Stone’s EZ-Key™ Precast Duct Bank is a patented system designed for data centers, airports, and major infrastructure projects requiring reliable pathways for high-, medium-, and low-voltage cables, as well as fiber cables. The system is engineered for faster installation, reduced on-site labor, and improved project predictability.
Each 10-foot section is designed for rapid installation using precision-engineered features, including alignment cones and Zip Pins that help ensure accurate connections with fewer installation steps.
Designed to Help Projects Meet Aggressive Timelines
Infrastructure projects are becoming more complex, and schedule delays can have significant impacts on budgets and overall project delivery.
EZ-Key™ Precast Duct Bank helps contractors streamline installation by arriving ready for placement. Instead of building duct banks entirely in the field, crews can focus on efficient installation and keeping projects moving.
The system is designed to reduce labor requirements, eliminate unnecessary installation steps, and provide greater consistency compared to traditional field-built methods.
Engineered for Performance and Reliability
At Roman Stone, every solution begins with engineering. Our in-house engineering team works closely with customers, contractors, and project partners to develop precast solutions that meet demanding infrastructure requirements.
The EZ-Key™ system was designed with durability and performance in mind. The system features a heavy-duty shear key connection designed to handle extreme loads, along with precision components that help create a consistent fit during installation.
Whether supporting a hyperscale data center, airport, or other critical infrastructure project, Roman Stone delivers engineered solutions designed for long-term performance.
Bringing Manufacturing Closer Through Mobile Precast Production
Large infrastructure projects often come with unique logistical challenges, including remote locations, demanding schedules, and high-volume production needs.
That is why Roman Stone offers Mobile Precast Manufacturing — bringing our production capabilities directly to the project site when needed. This allows customers to benefit from the advantages of precast while overcoming transportation and scheduling challenges.
With mobile manufacturing capabilities, Roman Stone can help deliver engineered precast solutions nationwide — wherever infrastructure is being built.
The Future of Underground Infrastructure Is Precast
As infrastructure demands continue to grow, construction methods must evolve. Faster installation, improved quality control, and smarter manufacturing approaches are becoming essential for successful project delivery.
Roman Stone’s EZ-Key™ Precast Duct Bank combines engineering expertise, manufacturing innovation, and nationwide capabilities to provide a smarter way to build underground infrastructure.
From traditional manufacturing to mobile production, Roman Stone is helping customers keep projects moving with engineered precast solutions built for the future.
