Improved geomembrane damage/leak detection through co-extrusion technology
- Gundle Lining Systems, Inc., Houston, TX (United States)
There has been a considerable advancement in technology available for providing a barrier system in the containment and storage of waste materials. Natural soil liners several feet in thickness have been augmented by factory-produced, synthetic materials that have permeability coefficients several orders of magnitude lower than any natural soil system. To carry the systems approach one step farther, engineers use multiple layers of synthetics separated at times by layers of clay offering a redundant composite barrier to protect the groundwater. Each geosynthetic material offers its own unique contribution to the system based upon its physical characteristics. Co-extrusion -- the process of combining two or more materials into a single product, through a single process -- is now revolutionizing the liner industry.
