Do you have any specific project information on the use of geogrids in constructing piggyback landfills, especially in cold climates? I am interested in examples of the use and evaluation of geogrids when building landfills over closed landfills. Any information you can provide as to landfill sites would be greatly appreciated.

Reply: The first use was at a landfill on Long Island, N.Y., 25 years ago. The theory is based on arching and is handled in my textbook, Designing with Geosynthetics, for this exact application.
I believe that there have been many uses since then and I consider it an ongoing technology. That said, the cold temperature should pose no material burden although installation may be inconvenienced or even delayed.
