ABOUT
Dong-A Geovan Co., Ltd.
Reading ground movements, building site safety.
Dong-A Geovan Co., Ltd. advances toward achieving zero risk at construction sites, offering everything from smart geotechnical monitoring sensors to unmanned automated monitoring systems.
The Global Standard for Construction Safety Technology
We set the standard for civil construction safety with precision that tolerates not even a single millimeter of error.
Since our founding in 1996, Dong-A Geovan Co., Ltd. has successfully deployed high-precision monitoring sensors and systems across South Korea's major nuclear power plants, large-scale dams, massive soft ground projects, and critical domestic construction sites that demand the highest levels of stability and precision.
By fusing advanced IT with the reliability of traditional civil engineering, we specialize in construction monitoring sensors and smart, unmanned, automated data acquisition solutions. We take full responsibility for safety throughout the entire project lifecycle, from the initial design phase to foundation completion.
Going beyond simple equipment supply, we serve as your most dependable technology partner, predicting and thoroughly defending against site hazards in real time.
