CPT TEST FOR JATILUHUR PROJECT BY TRIBINA WAHANA CIPTA

For accurate and sound site plans, SGS cone penetration testing services can determine your site strength and resilience. Talk to our qualified team today.

We use the most reliable, worldwide test, the cone penetration test (CPT). The CPT is an in-situ testing method used to determine the geotechnical engineering properties and delineate the lithology of your soil.

The CPT test method consists of using a hydraulic rig to push an instrumented cone tip into the ground through several rods. It continuously measures the resistance needed to penetrate the soil at a constant rate of two centimeters per second. The total force acting on the cone is called the cone resistance and qualifies the strength of your soil. The force acting on the sounding rods provides the total friction. Measurements with an electric cone, equipped with a friction sleeve, provide the local sleeve friction (CPT-E).

When the exact groundwater level has to be monitored, a piezometer is quickly installed to gather water pressure data. The thrust capacity of the sounding equipment is supplied by the truck’s ballast or by screw anchors to achieve extra reaction.

The information gathered is used to calculate the following geotechnical parameters:

  • Effective friction angle
  • Coefficient of consolidation
  • Bearing capacity
  • Settlement behavior of a foundation

This detailed set of calculations allows us to provide a comprehensive report with the right advice to ensure the suitability of your foundation plans.
