HDPE Duct Bank Spacers for Infrastructure Projects
As Phoenix and the broader Southwest continue to experience rapid growth, underground electrical infrastructure has become a critical foundation for new development. From large-scale utility projects to hyperscale data centers, proper conduit spacing and alignment are essential for long-term performance, safety, and code compliance.
HDPE duct bank spacers play a key role in these installations. Designed to maintain consistent conduit separation and structural integrity, HDPE spacers are now widely used in underground electrical construction throughout Arizona and the Southwestern United States. Regions where climate, soil conditions, and infrastructure demand place added stress on traditional materials.
With local inventory and fabrication capabilities, Piedmont Plastics in Phoenix supports contractors with HDPE sheet materials that can be machined to match virtually any conduit size or duct bank layout, helping keep projects on schedule as infrastructure demand continues to accelerate.

The Role of HDPE Duct Bank Spacers in Underground Electrical Construction
Duct bank spacers are used to separate, support, and align electrical conduits during installation and concrete encasement. These spacers help ensure uniform spacing between conduits, allowing proper concrete flow and reducing the risk of deformation or conduit movement during backfill and curing.
Plastic sheet–style duct spacers fabricated from HDPE are commonly used in:
Medium- and high-voltage underground electrical systems
Utility distribution and transmission projects
Commercial and industrial developments
Data center power infrastructure
By maintaining consistent conduit geometry, HDPE spacers support long-term electrical system reliability while helping contractors meet project specifications and inspection requirements.
Why HDPE Is the Preferred Material
Mechanical and Environmental Benefits of HDPE Spacers
HDPE duct spacers deliver both mechanical durability and environmental resilience, which is critical for infrastructure projects expected to last decades. These characteristics make HDPE spacers a reliable choice for long-term underground electrical systems.
Mechanical Benefits:
High strength-to-weight ratio
Resistance to cracking or breakage during installation
Ability to support conduit loads without deformation
Environmental Benefits:
Performs well in extreme heat, common in Arizona and the Southwest
Resistant to moisture, corrosion, and microbial growth
Maintains performance in both arid and humid soil conditions
Common Uses for HDPE Plastic Sheet Duct Bank Spacers
-
Data Centers
High-density power systems that demand precise conduit spacing and built-in redundancy.
-
Utility Installations
Infrastructure that supports municipal power distribution and underground utility networks.
-
Commercial Developments
Projects such as hospitals, university campuses, and industrial facilities requiring organized conduit routing.
-
Transportation and Infrastructure Projects
Applications where reliable underground electrical routing is critical to long-term performance.
Why Arizona and the Southwest Are Hotspots for New Infrastructure
Arizona and the Southwestern United States are experiencing unprecedented infrastructure growth. Population expansion, manufacturing investment, and increased energy demand are driving new underground electrical construction at scale.
HDPE duct bank spacers help contractors meet this demand by:
Supporting efficient conduit installation
Reducing rework caused by misalignment
Providing consistent spacing across large duct banks
Several factors have also made this region a prime location for new data center development. Data centers require extensive underground electrical systems to support power distribution, redundancy, and cooling infrastructure. HDPE duct bank spacers help ensure these systems are installed accurately and remain stable over the life of the facility.
