The foundation of every project: open the borehole, measure strength and stiffness and recover the undisturbed sample of the subsoil.
Geotechnical investigation reveals the characteristics and properties of the subsoil and its several strata. This understanding is essential for the proper design of a project and the consequent success of its execution.
The pages marked as "in preparation" already exist for navigation and SEO; the content follows in sequence.
Cone resistance, sleeve friction and pore pressure measured in real time every 2 cm of depth, the continuous profile of the subsoil with no sampling required.
View service →The benchmark test of Brazilian geotechnics: penetration resistance index and a soil sample every metre.
View service →The Marchetti blade measures soil stiffness in situ with high repeatability, modulus, horizontal stress and stress history.
View service →The thin-wall tube that recovers the undisturbed sample of soft soils, the sample the laboratory test requires.
View service →Rotary drilling with a diamond crown that recovers continuous core from rock and strong soils.
View service →Field vane test for the undrained shear strength of soft clays, measured in situ.
View service →Combines SPT in the soil and diamond rotary in the rock, in the same borehole, from the top to the founding level.
Page in preparationDouble-wall sampler for undisturbed samples in stiffer soils, where the Shelby does not penetrate.
View service →Undisturbed block hand-carved in an inspection pit: the highest-quality sample for advanced laboratory testing.
View service →Recovers a continuous soil profile, revealing the stratigraphy without the gaps of the SPT.
View service →Advance drilling for the installation of instruments and access, with no core recovery.
Page in preparationHollow helical auger that drills dry and allows sampling through the stem, ideal where water cannot be used.
View service →Ménard pressuremeter test: the probe expands in the borehole and measures the pressure-strain relationship of the soil in situ, for modulus and limit pressure.
