Six Observations from the Inspection of the 5-year-old geomembrane at the Knoxville, Tennessee World's Fair Park

Posted by Felon Wilson on Mar 23, 2022 8:14:14 AM

The lake at the Knoxville, TN 1982 World’s Fair Park was relined with the XR-5® Geomembrane in March 2016. We first published a video case history about the application and installation at the time here and here, along with some observations about the installation process itself. Then after 18 months of service, follow up observations were made here. After 5 years, I had the opportunity to be on site for the bi-annual cleaning of the decorative pond and then subsequently was able to inspect the material and get feedback from the Public Building Authority (PBA), the city department in charge of operating and maintaining the park, including the Lake.

NSF 61 Certification and Compliance for Potable Water Geomembranes

Posted by Felon Wilson on Mar 7, 2022 1:08:46 PM

The quality of the water we drink is pretty important. We assume we are protected by regulations that maintain high standards in our water, especially with the increasing use of geomembranes in potable water applications. But do all geomembranes comply? This blog will look at drinking water standards as they apply to geomembranes and how compliance should occur.

4 Potential Stresses and the 3 Strategies for Preventing Geomembrane Mechanical Failure

Posted by Felon Wilson on Feb 15, 2022 9:29:46 AM


Many engineers would argue that geomembranes are only fluid barriers and are not meant to be load bearing in any manner. All loads should be carried by geosynthetic counterparts, such as geotextiles, geogrids, etc., that are placed over and under the geomembrane. However, from a materials and installation standpoint, it is virtually impossible to transmit all load to the adjacent layers. Additionally, it is not usually cost-effective to build a heavily redundant composite system that takes all mechanical bearing off the geomembrane.
