Today's modern solid waste landfill is an Extremely secure containment for solid waste. They utilize a combination of Smooth and textured geomembranes (liners), geocomposites and geosynthetic clay Liners. these products have replaced natural materials such as sand and clay And have offered a much higher quality and more secure containment of solid Waste. A very common Lejeune Landfilllandfill base liner system design begins with a secondary liner on the prepared subgrade and then a geonet or geomposite On top of that liner. A primary liner is then installed. Finally, another Geocomposite is laid down to cover the primary liner layer. The geonet or Geocomposite that is between the liners is for leak detection, and the Geocomposite over the primary liner is for leachate collection and Transportation to sumps.  In the sumps, The leachate can be collected and treated. Shandong Tianhai has vast experience In the supply and installation of these products in landfill applications Throughout the country.
