Geotechnical Engineering Design Department

BUSINESS Geotechnical Engineering

“With the Best Qualified Engineers and the Best Technology”

We investigate and analyze the geologic structure of soils and strata, the condition of groundwater, and the characteristics of soils and each stratum.
It provides the engineering information and materials necessary for the design and construction of various structures planned on the ground. We will investigate
and collect all the necessary information for the design of the geotechnical structures and provide the stability of the structure
to our customers by constantly researching and experimenting with perfect design and construction by interpreting with the advanced technique.
