Geofilters control the ingress of fines and eliminates the need for additional filter material within the borehole. They are made up of a filter material that covers the outside of slotted or perforated pipe and an outer protective cover which is secured either end by adhesive or non-adhesive fixing.

Geofilters come in three styles to suit the needs and sizes of different projects:

  • Georap
  • Geosock
  • Geonet


  • Groundwater monitoring wells
  • Landfill gas monitoring wells
  • Dewatering wells


  • Easy to install
  • Filter to suit soil conditions
  • Drill smaller holes
