Application Range
Landfill Leachate Collection
When placed in intimate contact with a geonet or drainage stone, medium weight Nonwoven geotextiles can filter soil and waste while allowing water and leachate to pass. An efficient design utilizing recommended Nonwoven geotextiles can lead to proper leachate management in new landfill cells, and rapid surface water collection and removal in closure plans.
Product Construction
General Geotextile joints to connect. there is overlap, welding and oversew three ways.
Note:If geotextile joints to connect on the flat ground, overlap width>30cm.
If geotextile joints to connect not on the flat ground, overlap width>50cm
