DESCRIÇÃO DO ENSAIO
These surveys are carried out with mechanized drills that, by means of water injection under pressure and rotation of diamond crowns, perform the collection of samples at different depths.
Consult our team on tests in polls, such as Lugeon Test, among others.
The report of rotary drilling will present, in addition to the description and classification of the materials found, the SPT resistance index (in the ground stretches), readings of the water table level and percentage of recovery and RQD index (rock stretch). In addition, photographs of samples are presented in the rock section for proper identification of the cores.
