GCL as an Alternative to a Low Permeability Clay Layer or HDPE Lining Membrane
October 13th, 2009 by admin
The choice of Geosynthetic Clay Liner (GCL) may be a great option when the more normal Compacted Clay Liner (CCL) option is expensive or is not readily available in a region. Read about GCLs here!

Fabricated Geomembrane Institute Short Course Available in September
September 4th, 2009 by admin
The US Fabricated Geomembrane Institute (FGI) offers its popular short course, “Constructing with Fabricated Geomembranes“, on 23 October 2009 in Lakewood, Colorado. Those involved with the design, construction, operation and closure of potable water and irrigation ponds, floating covers, canals, landfills, waste water lagoons, secondary containment, golf course ponds, decorative applications, corrective action activities at closed sites, etc. are encouraged to attend.
Landfill Designers and Specifiers Beware of Blocked Drainage Layer Geotextiles
August 24th, 2009 by admin
Inferior geo-composite membranes which should both provide a low permeability membrane to cap a landfill and replace drainage stone otherwise needed above the low permeability layer are being offered which don’t do the job. It is essential to drain the interface and prevent development of a slip plane at the membrane on even quite gentle landfill slopes, but slip failures are inevitable if inadequate geo-composites are used. Find out how to avoid this pitfall.
Landfill Engineering and Environmental Conflicts
July 3rd, 2009 by admin
Landfill engineers are increasingly preoccupied with building landfills which will capture as much landfill gas as possible and use that gas optimally to generate renewable energy. However, this very engineering holds dangers for the environment around a landfill, with raised leachate levels, and extra stress on landfill lining membranes.
