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
 

Borehole Logging In-situ Testing:

1. Standard Penetration Test (SPT)

2. Cone Penetration Test (CPT)

3. Prebored Pressuremeters Test

4. Vane Shear Test

5. Single Packer Test/Double Packer Test

6. Rising Head Permeability Test / Falling Head Permeability Test

7. Acoustic Televiewer Survey / Optical Televiewer Survey

8. Dilatometer Test

9. Hydraulic Fracturing Test

10. Plate Load Test

11. Downhole Seismic Survey  (please refer here for more information)

12. PS  Suspension Logging (please refer here for more information)

Sampling:

1. Undisturbed Sampling:
