The process

PT. BSG serves Geotechnical Engineering Investigation, includes:
- Soil / Rock Core Drilling and Sampling
- Standard Penetration Test (SPT)
- Cone Penetration Test (CPT)
- Soil / Rock Mechanical Reporting
- Insitu Permeability Test (Packer Test Constant Head / Falling Head)

Soil/Rock Core Drilling and Sampling

PT. BSG have 5 unit imported drilling machines for soil/rock drilling and sampling with maximum 100 m depth. YBM YSO 01, YBM YSO 05, Toho, Yamaguchi in good performance will be running for service our client. Drilling machines use for obtaining a soil sample for visual/laboratory inspection and supporting Standard Penetration Test (SPT) or other test.

Standard Penetration Test (SPT)

The standard penetration test is an in-situ test that is coming under the category of penetrometer tests. The standard penetration tests are carried out in borehole. The test will measure the resistance of the soil strata to the penetration undergone. A penetration emphirical correlation is derived between the soil properties and the penetration resistance.

Cone Penetration Test (CPT)

The CPT is a valuable method of assessing subsurface strati-graphy associated with soft materials, discontinous lenses, organic materials (peats), potentially liquefiable materials (silt and sands), and landslides. CPT can be easily quickly mobilize to site and relatively quick simple and economical.
