The purpose of landfill capping

Landfill capping design system for non-hazardous and hazardous landfills should prevent the intrusion of precipitation into the waste or the release of landfill gases from the waste.

Sensor's DDS® FIXED systems offer a long-lasting solution, guaranteed by BAM certification to monitor geomembrane integrity for over 30 years.


Landfill capping design cross section (from bottom to top):

  • Waste
  • Leveling layer
  • Gas vent (50cm)
  • Protective geotextile
  • Soil (35cm)
  • Geomembrane
  • Top soil (30cm)
  • Vegetation

The sensors are tested on site prior to installation.

Every single sensor is connected to monitoring box via cable.

Sensors are installed directly to clay layer or subsoil.

5x5m sensor grid was applied on landfill capping.

After liner installation we controlled whole surface using SENSOR DDS® MIT before other layers were laid down.

Landfill capping prevents contamination to spread into the environment.

Re-cultivated landfill which is regularly monitored for leaks. Making it environmentally risk free.
