Conduit and Duct Support Material Solutions Built for Underground Durability

Interstate Advanced Materials delivers conduit and duct support system material solutions designed for long-term performance in underground environments.

SACRAMENTO, CA, UNITED STATES, April 30, 2025 /EINPresswire.com/ -- Interstate Advanced Materials delivers conduit and duct support system material solutions designed for durability and long-term performance in demanding underground and outdoor environments. These materials enhance system safety and reliability while reducing maintenance and installation costs across utility, construction, transportation, and energy infrastructure projects.

In trench installations, spacer cards offer a safer, more consistent alternative to traditional “stacking chair” methods. Made from reprocessed HDPE or fluted polypropylene, spacer cards provide uniform conduit alignment, load distribution, and separation. This prevents shifting, collapse, or conduit deformation during encasement, helping preserve system integrity over time and improving safety for workers during installation.

To further support conduit stabilization, Interstate Advanced Materials offers materials for conduit retaining devices (CRDs). CRDs are used in duct bank installations and underground utility vaults to keep conduit in place before encasement, improving structural reliability. These solutions streamline installation and improve efficiency on the job site.

Materials such as reprocessed HDPE, fluted polypropylene, and PVC Type 1 offer durable alternatives to wood and metal for various conduit and duct support applications. Reprocessed HDPE is ideal for conduit spacers, support rails, trench panels, and mounting plates, with toughness suited for direct burial in harsh soil. Fluted polypropylene is lightweight and water-resistant, making it well-suited for divider panels, conduit shims, bore spacers, and temporary shielding, while also allowing for easy on-site customization. PVC Type 1 supports wall-mounted brackets, cable trough dividers, and utility vault spacers, offering non-conductive, corrosion-resistant performance in buried and exposed environments.

Interstate Advanced Materials maintains strong partnerships with domestic extruders, ensuring steady supply and competitive pricing. Its long-standing relationships support fast delivery and product availability for large or time-sensitive projects, streamlining logistics and minimizing project delays.

Operating five processing machines across multiple shifts, the company delivers the production capacity and flexibility needed for fast turnarounds and consistent quality. This enables dependable support for projects with tight schedules or variable scopes.
