Micro Zoning Surveys,
Line / Route Surveys,
Consolidation Analysis of Stowage,
Natural Building Materials Research Studies are carried out.
Cylinder core sampling drillings with vertical angle (90°) based on the area and depth (depending on the bulb of pressure effect) on which the descriptive geometry (load) of the structure will have effect and in-situ tests (Pressiometer, Standard Penetration Test, Pressurized Water Test, Permeability,…) that are suitable for the rock /ground over these drillings are performed.
During the drillings, SPT tests are performed at every 1.5 m in units defined as the ground by ISRM, and remolded soil sample are taken by means of UD tubes at every 3 m during SPTs. If it brings forth Refusal 3 times consecutively during the SPT tests, the progress on the ground is stopped by the Auger Method and with the core sampling technique, the drilling is resumed on.
The Geological Strength Index (GSI) and Rock Mass Classification System (RMR) are determined by carrying out the evaluations of fault joint systems of the coring samples taken from the rock units passed during the drilling, direction and dips of these systems, and rock mass (RQD, TCR and SCR).
In the ground/rock mechanics laboratory, experiments of Ground/Rock Mechanics are made by selecting samples that are eligible to represent the ground and rock units and which belong to the project area as a result of the correlation of the drillings in the ground and rock samples that are taken during the drilling.
Mitto Consultancy; Thanks to its multidisciplinary engineer staff and academic advisors with long-term cooperation, we are able to carry out the Geotechnical Survey Practices that you need accurately and create complete reports in accordance with the standards.
