Surveys, tests and analyses on the ground to ensure safe foundations, structural stability and conscious designs.
Geognostics
Geognostic surveys are the main direct method to investigate the subsoil. They allow the analysis of geological and geotechnical characteristics through the through core sampling, the execution of in-hole tests, the execution of tests in the borehole (geotechnical, geophysical and hydrological) and sampling for laboratory analysis. The boreholes can also be used for the installation of sensors for monitoring groundwater and inclinations
Pressuremeter Test
The pressure test measures the deformability and resistance of soils and soft rocks through the controlled expansion of a cylindrical probe in the borehole. The data obtained (limit pressure and pressuremeter modulus) allow the mechanical behavior of the investigated materials to be assessed.
Inclinometric Monitoring
Inclinometer measurements allow monitoring of horizontal ground movements along the depth through a probe inserted into a guide tube. The analysis of changes over time makes it possible to identify movements and the depths of sliding surfaces. We use both manual and automatic systems with remote control.
Marchetti Seismic Flat Dilatomer
The DMT test involves vertically inserting a blade-shaped testing instrument into the ground using static thrust, expanding a circular membrane located on one side of the instrument with pressurized gas, and measuring the pressures corresponding to two predetermined levels of membrane deformation. The seismic module allows the S-wave velocity profile to be obtained with depth.
