Fibrelite reports that since the start of its partnership with Trenwa more than 100 precast trench systems integrating Fibrelite composite covers have been sold for use in electrical substations, wastewater treatment plants, chemical refineries and many other applications across North America.
In 2014, Fibrelite and precast concrete trench manufacturer Trenwa formed a strategic partnership to create joint product offerings: Trenwa’s heavy-duty precast concrete road crossing trenches topped with Fibrelite’s traffic-rated composite trench covers. Together they provide long-term protection for underground utilities running across road crossings while enabling safe and fast manual access for monitoring and maintenance.
“Combining high-performance, lightweight Fibrelite covers with our low-cost precast trench bases delivers a very high-value solution for our customers,” reports George Schurr, President/COO, Trenwa. “They get unparalleled strength and durability at a lower cost than has ever been seen in the market.”
Trenwa and Fibrelite’s road crossing trench was recently recognised during JEC Group’s first edition of the Future of Composites in Construction, where it featured in the Innovation Hub.
To meet demand from companies looking to upgrade previously installed concrete or steel trench covers, Trenwa has worked with Fibrelite to design and manufacture custom moulded composite trench covers to fit Trenwa’s existing line of precast multi-duty trench systems. These covers are engineered specifically for light vehicle traffic (12.5-tonne load rated) and pedestrian traffic (1.5-tonne load rated) respectively.
Precast concrete trenches are used on substations to carry and protect the large amounts of electric conduits and cabling required. Where trenches cross access roads, load ratings of HS20 are required to handle heavy-duty vehicles such as cranes.
“I am excited to see our partnership with Trenwa growing as their customer base continues to adopt our lightweight, corrosion resistant composite trench covers,” notes Jim Goodman, US Key Account Manager, Fibrelite.
