Fibrelite and Trenwa’s Partnership Trench Systems

Two Industry Leaders

Three Joint Product Lines

“Combining high-performance, lightweight Fibrelite lids with our low-cost precast trench bases delivers a very high-value solution for our customers. They get unparalleled strength and durability at a lower cost than has ever been seen in the market.”

George Schurr, President/COO, Trenwa Inc.

In 2014, Fibrelite and precast concrete trench manufacturer Trenwa formed a strategic partnership in North America to create a joint product offering: Trenwa’s heavy-duty precast concrete road crossing trenches topped with Fibrelite’s traffic rated composite trench covers.

Since then, our partnership has gone from strength to strength, with hundreds of the partnership systems sold and installed in electrical substations, wastewater treatment plants, chemical refineries and many other applications across North America.

In 2017, we developed two new composite covers in partnership with Trenwa, designed to meet demand from their customers to previously installed metal and concrete covers over existing trenches.
