Geosynthetics

Geosynthetics are man-made polymeric materials used for geotechnical application. They are used in lieu of conventional materials and often are more cost effective with equal or improved engineering performance. The intent of this module is to provide general guidance to the practicing geotechnical designer on the proper use of geosynthetics for both design and construction. The key assumptions of this module is that the user has sufficient overall geotechnical experience and is already familiar with general civil engineering and construction practices and uses professional judgment in the decision to use and specification of geosynthetic materials. This module closely follows the design and construction procedures provided in the FHWA Publication No. FHWA-NHI-07-092 “Geosynthetic Design and Construction Guidelines” (Holtz, et al., 2008) hereafter referred to as the FHWA manual with other references cited as needed within appropriate sections of this module with a complete list given in Section 4.
