Abstract
As capping materials of landfill site, hybrid geosynthetics which consist of porous sheet and nonwoven geotextiles have been developed. Characteristics on waterproof and gas permeability of these hybrid geosynthetics were examined by laboratory tests. Construction test was also conducted to evaluate construction durability of them under the real configuration of capping technology in landfill sites. As the results, the newly developed hybrid geosynthetics have very good characteristics on waterproof, gas permeability and construction durability, and are available to apply practically to landfill sites.
