Inflatable Packers

Global Geotech supplies a selection of inflatable packers for use in boreholes in the diameter range 30 – 350 mm.

These have a wide range of applications including:

  • Injection of grout into boreholes
  • Permeability testing of rocks
  • Water sampling
  • Taking impressions inside a borehole

Inflatable packers are manufactured using layers of steel cable embedded into natural rubber, giving them the strength to resist rough conditions of the worksite whilst at the same time providing them with an exceptional expansion capacity.

The deflated packer is lowered into a borehole and is then inflated using water or gas injected through an inflation line. The large expansion enables a good seal to be achieved in both smooth and uneven boreholes, as well as facilitating running in and retrieving.
