SOIL INVESTIGATION

COMBINING CONVENTIONAL DRILLING METHOD EFFECTIVELY WITH TECHNIQUES OF GEOPHYSICAL SURVEY

The process of identifying and establishing  types of soil layer/strata for the area of interest are broadly known as soil investigation. Drilling of boreholes are usually done to obtain soil samples which are subsequently sent to our laboratory for examination and processing. Our team of high trained staff will aid in providing meaningful information from the soil data obtained for our clients. We are also able to propose design and build proposal based on information and field logs. 

SPECIALISATIONS OF DRILLING METHOD

Techniques (Including proposal and budget estimation):
• Borehole drilling and coring
• Laboratory testing
• In-situ testing
• Building construction
• Bridge foundation
• Slope construction
• Equipment foundation
• Rock, or soft-zone mapping
