Carbon footprint implications of the erosion control response

From the Geosynthetics Research Institute’s 24th conference, 2011.The articles in this series encompass all types of geosynthetics and their applications viewed from the context of sustainability. Traditional solutions are compared with geosynthetic solutions from both cost and carbon footprint perspectives. (from the Geosynthetic Research Institute’s 24th conference, 2011) Introduction Many geosynthetic erosion control technologies are …

The need for erosion control material specifications

By Bob & George Koerner The authors feel that a reasonable case can be made that generic specifications have significantly aided both geotextile materials (e.g., via AASHTO specs) and geomembrane materials (e.g., via GRI specs). Such specifications address most common situations and also provide a platform from which unusual or atypical site-specific conditions can be …
