History

Forty years ago, we set the standard for durable, dependable geosynthetic products. Learn more about where we’ve been and how it’s influencing where we’re headed.

GSE's origins can be traced back to Schlegel Lining Technology and Gundle Lining Systems, which pioneered the first high-density polyethylene product in 1972. Over the next four decades, the company evolved into GSE and became a global industry leader. During that time, GSE built a well-oiled machine that produces durable, dependable geosynthetic lining products and systems.
