Why Use a Geomembrane?
Geomembranes are thin, permeable fabrics that are used in a variety of civil engineering and construction applications. They are made of synthetic fibers such as polypropylene or polyester and are used to separate, filter, reinforce, protect or discharge soil or other materials. Why Use a Geomembrane? Essential for unpaved roads. Peter G. Nicholson in Soil Improvement and Ground Improvement Methods states, "Geomembranes play an important role in providing working solutions for building or improving secondary unpaved roads, haul roads, access roads and roads in developing areas." Peter G. Nicholson explains that in most cases, geomembranes are placed between soft, fine-grained roadbed soils with stones or sand on top. He also highlighted how the geotextile's separation function prevents aggregates from mixing into the roadbed, thereby improving the long-term performance of the unpaved surface. Separation of soil layers. The most common and obvious...
