Cone Penetration Test
Cone penetration testing (CPT) is an investigative method used to examine and record the geotechnical engineering properties of soils. A universally trusted soil investigation method, geotechnical cone penetration tests can be deployed from the ground surface with a variety of rigs, or over water from barges and platforms.
The data extracted from a cone penetration test can be used in site assessments to determine the liquefaction-triggering resistance present in each layer of soil. CPTs are used extensively across a range of industries for a wide spectrum of marine and land applications, such as:
Geoenvironmental investigations to determine foundation depth, characterise contamination and map subsurface obstructions
Hydrogeological applications like water resource investigations and determining hydraulic behaviour
Geohazard studies such as investigating shafts, mines and natural cavities
Quality control checking earthworks and compaction testing.
Cone penetration testing is a cost-effective investigative method that provides a broad spectrum of information and delivers high volumes of data with less environmental impact than other testing methods. Further benefits include:
Cone penetration tests can be deployed on both land and water
Low impact testing that provides a continuous subsurface picture
Provides big data in real time with rapid acquisition for reliable site characterisation
Cone penetration tests meet universal quality standards and design codes.
