Soil investigation covering both land and marine exploration works remain one of the flagship services of Ryobi G.  It involves the process of identifying and establishing the types and layering of soil/rock for the area of interest which consisting mainly of field exploration via borehole drilling/filed testing and laboratory testing. Drilling of boreholes are usually done to obtain field test data and soil samples which subsequently sent to our SAC-SINGLAS accredited geotechnical laboratory for analysis. Typically for examination and determination of engineering parameters which are essential in achieving safe and economical geotechnical design and construction control.
