Springtime failure of a cold-climate geotextile riprap slope

June 1st, 2018

Geotextiles play an essential role in geotechnical projects. A significant use for geotextiles is as a separator and filter in drainage and erosion control applications (Holtz 2002). A temporary erosion control application geotextile, such as silt fencing, is used to prevent soil erosion by containing the soil and turbid water in a onetime operation. For […]

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 […]
