LLT-M

The LLT-M is a borehole lateral load tester that functions to determine the deformation characteristics of the ground from the relation between pressure inside its sonde and the inflated amount of its rubber tube.

The instrumentation on the surface consists of a tank for producing pressurized water, pressure gauges, valves, etc. It is mainly featured by the applicability of different sizes of sonde, which makes it possible to choose a sonde suitable for borehole diameter.
