ROCK CORING

AND SAMPLING

Rotary surveys are used to study rock masses, through the collection and classification of rock cores.

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.

RESULTS PRESENTATION

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.
