The majority of our industry is familiar with the Geosynthetics Magazine published by the Industrial Fabrics Association International (IFAI) which provides a forum for consistent and accurate information to increase the acceptance and promote the correct use of Geosynthetics. It is the primary news source for our industry.
In the February/March 2009 issue, ILT was highlighted as the installer in an article about Geosynthetic clay liner (GCL) shrinkage and possible solutions.
For those of us who don't know what it is, GCL is typically used in place of clay for permeability physical characteristics. "The geotextiles offer a long lasting resistance to physical or chemical break-down in harsh environments. The bentonite's high swelling capacity and low permeability provide an effective hydraulic seal." Cetco.com, Cetco, 9 Apr 2009.
The purpose of the article was to show the field techniques and observations used on a 150 acre lining project done by ILT. The article presents information that the installation may provide a possible solution in regards to GCL shrinkage due to the technique ILT used for heat-tacking every GCL seam.
The site of installation was the Carlota Copper Mine. The mine is under development near Miami, Arizona. It is owned and operated by Quadra Mining of Vancouver, British Columbia. The mine uses heap leach technology to extract metals from mined rock ore by leaching the poles of mined ore with various solutions that dissolve the desired mineral. The bottoms of these leach piles are designed with geomembrane liners and liquid collection systems.
Our gratitude goes out to the writers of the article Richard Thiel and Chris Thiel for bringing this issue to forefront with a possible solution. For the complete article you can download this issue from http://www.ifai.com/Geo/0209GS_TOC.cfm.
