About Us

We're more than just a liner company. We set the standard for everyone else to follow in the industry.

Laying the Groundwork

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.
