In many cases distances are of vital importance: snow height in an avalanche rupture zone, the width of a crack in presumably unstable rock or the distance to a water surface in order to determine flow height. Our crack meters are ideal to measure crack movements very locally and precisely.
For precise measurements of movement along single cracks, our crack meters supply measurements with precisions below 1mm. A similar accuracy can also be reached with our interferometric georadar – but across whole faces of rock. Combining both technologies lets us determine the critical zones in an unstable rock face in order to place the crack meters exactly where they are needed most.
Boreholes equipped with extensometers additionally let us detect movements deep within the rock or ground – at precision of 0.1 mm and at a wide range of different depths.
Depending on the situation, data from these measurements can be transmitted to our servers by radio or cable connection.
Many of our clients rely on our crack meters to reliably measure crack deformation at the sub-mm levels. Georadar measurements can help identify critical zones to place crack meters in the best locations.
