| Tendrain for Leak Detection System (LDS) | ||||||||||
|
Volusia County, FL |
||||||||||
 At this landfill in Volusia County, Florida, a leak detection system was developed which required a geonet that would limit intrusion of the GCL into the flow channels of the geonet. The problem of GCL intrusion results in a reduction of flow through the geonet, a situation that was unacceptable on this project. Project engineers, however, discovered that the structure of Tenax Tendrain was ideal for use with GCLs because the very structure of Tendrain prevents intrusion into the drainage channels. Tendrain was therefore deployed on this project in the leak detection system, to provide rapid detection of any major breach in the primary liner system, and to limit the head acting on the secondary liner to lengthen the thickness of the LDS.
