Geotextile fabrics are extensively used in the design of both top and bottom layers of landfill facilities. Used for filteration purpose or as cushion to protect the geo-membrane from puncture. A geotextile protection layer beneath the gravel provides a cushion to protect the primary geo-membrane from puncture by stones in the overlying gravel. Geotextile filter covers the entire footprint of the landfill and prevents clogging of the leachate collection and removal system. The ground water level may be controlled at the bottom of the landfill by gradient control drains built using geotextile filters.
- Protect and prevent geo- membrane layers from puncture.
- Provide separation layers to preserve landfill design.
- Feciltate flow through drainage systems and landfill layers.
