Clarifying the nomenclature of Elvaloy-based geomembranes: EIA, EIP or KEE

June 1st, 2019

By E. Silva and T. D. Stark  Since the first flexible membrane liner (FML) was used as part of an environmental liner system, the geomembrane industry has always looked for innovative solutions for chemical containment applications. Although there have been many innovations over the last 50 years, one of the most significant is the introduction […]

Using geosynthetics for macroencapsulation for CCR on-site clean closure

August 1st, 2017

Coal combustion residuals (CCR) have been used for many years in the construction of berms and engineered structural fill applications, including embankments for highways, dikes, and levees. However, large, unencapsulated structural fill projects have become a focus of environmental concerns due to potential leaching of metals and structural failures. Cap-in-place of CCR surface impoundments is […]
