We don’t just claim to be the best in the industry – we can prove it. Read our case studies to learn how even in the harshest environments and the most demanding applications around the world, GSE’s innovative products and dedicated team of experts have delivered cost-effective, reliable lining systems that help protect the environment and our customers’ bottom line.


Leak Location Liner Helps Put Aeration Basin Back in Business The Town of Thompson’s Station, a community south of Nashville, TN, has experienced a surge of economic growth. In the spring of 2012, Aeration Basin 2 at a town wastewater treatment plant was in need of repair. After considering several alternatives, the Project Team decided to reline the basin.
GSE StudLiner Proves the Perfect Choice for County Sewer The Strathcona County sanitary sewer line had serviced over 26,000 people in the 35 years it had been in operation. Over time, the original concrete pipeline suffered various degrees of hydrogen sulfide corrosion within the obvert section of the pipe. Root intrusion had also caused poor structural conditions in various locations.
GSE's Electrically Conductive Geomembranes Perform at Large Mining Operation GSE constructed a reservoir with a double synthetic liner and leak detection drainage layer. A 60 mil (1.5 mm) secondary liner of GSE Conductive, GSE HyperNet drainage net and an 80 mil (2.0 mm) primary liner of white-surfaced GSE Conductive comprised the system. The project used a total of 1.7 million square feet (160,000 square meters) of geomembrane.
GSE's Pond Liner System Still Holding Up After Three Decades One of GSE’s earliest projects was for a steam electric generation station in Colorado. For this power plant application, we lined eight containment ponds ranging in size from less than an acre to over 20 acres. The ponds are used to store intermediate quality water, for fly ash recovery and as brine ponds.
GSE Lining Eliminates Water Loss in Putah South Canal The Putah South Canal in Vacaville, CA, which supplies irrigation water for the Solano Irrigation District, was having a continuing problem with seepage. After only partially mitigating the problem by lowering the surface height of the canal water, the decision was made to reline the worst section of the canal, which was about 4,000 feet in length.
GSE Lines 59,000 Feet of Canal in Mountains of Peru GSE was called upon to line the newly constructed Pasto Grande Umarzo Canal project in the mountains of Peru. The concrete-lined canal measures 59,000 feet (18 km) and supplies drinking and irrigation water to an agricultural community.
GSE Bentoliner Contains Wet Process Ash for a 3,520 Megawatt Facility GSE supplied approximately 1,000,000 square feet of our innovative GSE Bentoliner CAR (Coal Ash Resistant) Geosynthetic Clay Liner (GCL) to a 3,520-megawatt Southeastern United States for the containment of wet process ash. The owner insisted that no GCL additives used be toxic or enhance any microbial growth in the surrounding soils and water table.
GSE Helps Launch of a New Arizona Power Plant GSE GundSeal GCL was installed as the secondary composite liner system for six cooling and process ponds at the Springerville Power Plant in Northeast Arizona.
