Geosynthetics and erosion control

February 1st, 2018

Terra firma often does not morph in ways that modern society appreciates. Erosion from stormwater, snowmelt, long-term water flow and unrelenting waves sweep away soil and rock from steep slopes, riverbanks, ditches, channels, shorelines, building foundations and much more. To understand the power of erosion, simply think about the Grand Canyon, which was formed by […]

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 […]
