Lankelma - Cone Penetration Testing Services
Cone penetration testing (CPT) is an in-situ test whereby a cone penetrometer mounted to a series of steel rods is vertically pushed into the ground. Hydraulic rams on our CPT rigs push the cone penetrometer at a constant rate of 20 mm per second to depths of up to 100 m.
Services Details
Lankelma offer popular piezocone testing, as well as a number of specialist cones that can be run concurrently to test different geological environments and evaluate a range of soil parameters. The CPT platform is also useful for obtaining samples and undertaking geotechnical installations.
Why choose Cone Penetration Testing?
CPT is ideal for testing a range of soils, with the cone penetrometer measuring the in situ stress conditions and shear strength; CPT results can be used directly for piled foundation design in sands and gravels.
- Fast, efficient and cost-effective data gathering and handling
- High quality, repeatable results, available in real time, allowing on-site selection of the best locations for testing, sampling and monitoring
- Low environmental impact: CPT is quiet, with no vibrations and minimal soil disturbance, creating very little waste
- Preliminary results can be issued the next working day
- Data can be used directly in geotechnical design.
