From those early days of Schlegal Lining Technology and Gundle Lining Systems for pioneering high density polyethylene, GSE has expanded and evolved from a one product manufacturer in 1972 to a global company.

Today, GSE offers the largest selection and highest quality geosynthetic products on the market. Our expertise from product specification through technical support demonstrates an advantage that no other geosynthetics company can match with solutions backed by The Pioneer of Geosynthetics.
