ABOUT
Twenty years
in the field
Founded in 2006 under the name Tuna Mühendislik, our company has operated since 2011 as Tuna Yerbilimleri Ltd. Şti., carrying out soil investigation, soil drilling and geophysical survey work in every region of Turkey.
WHO WE ARE
Solid ground, built on science
With our corporate structure and field teams, we prepare geological-geotechnical study reports for ministries, governorships, municipalities and private-sector organizations. From drilling to the laboratory, from geophysical survey to reporting, every step follows our own discipline.
By the nature of our work, it makes no difference whether it's snow, mud, mountainous terrain or a tight site within a residential area: the program is built around the site, data is collected in full, and the report is delivered in full compliance with regulations.

OUR VISION
To be a benchmark engineering firm that advances a culture of safe construction in every region of Turkey.
OUR PRINCIPLES
Three principles behind every report
Scientific Rigor
Every report is based on measurable field data, laboratory results and engineering calculation. Data speaks — not assumption.
Regulatory Compliance
Reports are prepared in full compliance with current legislation and the earthquake code; institutional approval processes are followed closely.
Field Discipline
In winter snow, at the bottom of a valley, within a tight residential site — whatever the conditions, the field program is completed in full.
