Borros Type Hydraulic Anchor | For use in soft soils and clays, especially in augered boreholes. Can also be driven directly through soft ground without a borehole being required (please see the Model 1950 data sheet).
Groutable Anchor | The preferred anchor for use in downward-directed boreholes. The preassembled extensometer is installed in the borehole and is then filled with cement grout. These anchors can also be used in upward-directed boreholes with a more complicated grouting procedure.
Hydraulic Anchor | For use in rough boreholes in rock and soft ground, especially if dilations and contractions of the borehole are anticipated. Also useful in upward directed boreholes with or without grouting.
