SOIL INVESTIGATION

COMBINING CONVENTIONAL DRILLING METHOD EFFECTIVELY WITH TECHNIQUES OF GEOPHYSICAL SURVEY

The process of identifying and establishing the types and layering of soil/rock for the area of interest are broadly known as soil investigation 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 are subsequently delivered to our laboratory for examination and determination of engineering parameters which are essential in achieving safe and economical geotechnical design and construction control. The ground information profile obtained from borehole drilling can also be enhanced by Geophysical Survey which is one of the strong specialized fields of Ryobi-G. Our team of highly trained staff will aid in providing accurate ground information and practical geotechnical parameters from the soil investigation works carried out for our clients. We can provide quotation according to client’s specified work schedule and also able to propose comprehensive soil investigation package based on site and project conditions including geotechnical analysis and recommendations.
