Installation Procedure

� Mechanical packers for grouting structures are anchored in the borehole by screwing, firmly pressing the fabric reinforced rubber sleeves to the borehole wall

� This procedure ensures that the packer remains in the borehole even at high injection pressures. Smaller deviations in terms of borehole shapes or borehole diameters are compensated to prevent material from emerging out of the borehole

� Inflatable packers for deep boreholes automatically tension in the borehole at an opening pressure of approximately 30-40 [bar]
