Landfill & Basins

Landfill and lined basin design: liners, leachate and stability

Landfills and lined basins must hold waste or water safely for decades. Their design combines geosynthetics, drainage and geotechnical stability.

Liner systems

  • Compacted clay liners
  • HDPE geomembranes and geosynthetic clay liners
  • Protection geotextiles
  • Leak detection layers

Leachate and drainage

Collection pipes and drainage layers remove leachate or seepage to a sump for treatment, reducing pressure on the liner.

Stability and capping

Side slopes, liner interfaces and final caps are checked for sliding and settlement, including under seismic and wet conditions.
