This paper looks at the use of fabricated geomembranes and the numerous cost advantages of these materials. The reduction of installation time and testing is particularly important in harsh environments and fabricated geomembranes can be used to extend the “field installation season.” Further the reduced installation cost is derived from the use of large factory fabricated panels that reduces the amount of field seaming and field personnel time that is required. Additional savings can be found in the reduction of third party Construction Quality Control costs. The paper describes how Construction Quality Control standards are maintained by conducting CQC prior to the geomembrane being shipped to the jobsite.
