GSE Environmental Announces Patent of GSE CoalDrain Geocomposite


HOUSTON — (February 14, 2017)   GSE Environmental, the leading global manufacturer and marketer of geosynthetic products and solutions, announces the patent of GSE CoalDrain, a highly engineered geocomposite designed specifically for Coal Combustion Residuals (CCR). GSE CoalDrain replaces the filter layer and the leachate collection layer in a typical Subtitle D liner system. Extensive laboratory and field performance tests have demonstrated that GSE CoalDrain geocomposite effectively allowed for unimpeded flow of liquids and did not let coal ash particles pass through.

The CoalDrain patent (US patent #9566775, entitled Geosynthetic Composite for Filtration and Drainage of Fine-Grained Geomaterials) by the USPTO recognizes the GSE innovation, and protects the company’s years of R&D investment and interest in this field.

Previously, GSE introduced its one-of-a-kind Coal Ash Barrier System in response to increasing concerns and pending legislation regarding coal ash containment and potential groundwater contamination. GSE collaborated with leading utility companies, U.S government officials, and Ohio State University to develop the system that combines three of the company’s proven geosynthetic products that meet or exceed regulatory standards: Leak Location Liner, BentoLiner Coal Ash Resistant Geosynthetic Clay Liner, and CoalDrain.

At the time of the launch, Steve Eckhart, Vice President of Marketing, said, “The Coal Ash system will not only provide our customers with a faster, more reliable way to contain coal ash, but it opens up a host of future opportunities to positively affect the environment and the energy industry around the world.”

GSE Environmental is a global manufacturer and marketer of geosynthetic barrier systems, stabilization products, and drainage systems used for the containment and management of solids, liquids and gases for organizations engaged in civil engineering projects, waste management, mining, water, wastewater and aquaculture. GSE's principal products are polyethylene-based geomembranes, geonets, geocomposites, geosynthetic clay liners, concrete protection liners and vertical barriers. Headquartered in Houston, Texas, USA, GSE maintains sales offices throughout the world and manufacturing facilities in the US, Germany, Thailand, China and Egypt.
