Fabric packer

Fabric packer for geothermal probes

In connection with an installation of double U geothermal probes fabric packers are suited for sealing and controlling artesian confined groundwater as well as for sealing gaps.


  • Fabric packers can allow for an installation of geothermal probes also in the case of challenging subsurface conditions.
  • Installation of the packer in the overall system without damage to the probe pipes, no couplings, connectors etc.
  • Separated injection below and above the activated packer route (filter fabric hose) possible.
  • Use of customary backfilling materials as injection means.
  • Materials harmless from the point of view of environmental chemistry.
