The following questions have been asked by one of our readers: "Has anyone experienced the floating of the primary geomembrane of a lining system consisting of a geomembrane/GCL composite primary liner, a geonet leak detection layer, and a geomembrane secondary liner?" Please send comments to info@geosynthetica.net. In a similar vein, "If there is a 3 m head of water on a single HDPE geomembrane liner with no water underneath it the geomembrane will obviously be in intimate contact with the subgrade. But if the groundwater is 0.5 m above the floor of the pond, and there is no leak in the geomembrane, where will the floor geomembrane be?" a) on the subgrade b) floating at 0.5 m or c) elsewhere Comments to info@geosynthetica.net.

John R. Starr has released a market analysis titled "World Supply and Demand Outlook for Spunbonded Polyester Nonwovens." World demand is expected to increase by 80,000 tons over the next several years despite the trends towards lighter weight fabrics, according to Starr. The report also has detailed information about the emerging spunbonded polyester medical fabrics market and the established roofing market. Filter media, and other end-use applications are discussed.
