From that day in 1979 forward, Xerxes has provided fiberglass underground fuel and water storage tanks to customers ranging from major oil companies to international convenience store chains, from medical centers to educational facilities, from airports to national parks. Everywhere we live and work: our products provide innovative and durable solutions.

Our latest product expansion continues the work.

In 2021, Xerxes proved once again that its mission is to innovate and deliver the technology necessary to respond to evolving market needs. With a growing awareness of the need to protect and manage our water resources, we introduced our line of stormwater products – HydroChain™ Stormwater Management Systems. Through partnerships with third-party manufacturers, our expert teams create site-specific solutions for our customers. Our advanced stormwater treatment components, thermoset stormwater chambers and other thermoplastic products are a natural expansion of our industry-leading fiberglass tanks.

We proudly step into the future as part of the Mattr family of brands.

In 2019, Xerxes became part of Shawcor, a global energy and infrastructure technology company based in Toronto. In 2023, when the streamlined and repositioned company was renamed Mattr, Xerxes became a key brand of the new company whose mission is to innovate and deliver highly engineered products and systems that will create the critical infrastructure our world needs.
