Sesco Survey and Engineer Limited provides expertise to the area of Cone Penetration testing with measurement core water pressure (CPTu) and has led to the development of in-house data acquisition and data management systems. The Company operates of CPTU rig with capacities ranging from 50kN to 100kN wheel drive systems. This selection of CPTu’s gives our Clients a range of options when deciding on the most effective tool for a project thus helping to obtain the highest data quality possible.
Cone penetration testing (CPT) is an in-situ test that is used to identify the soil type. In this test a cone penetrometer is pushed into the ground at a standard rate and data are recorded at regular intervals during penetration. A cone penetration test rig pushes the steel cone vertically into the ground. The cone penetrometer is instrumented to measure penetration resistance at the tip and friction in the shaft (friction sleeve) during penetration. A CPT probe equipped with a pore-water pressure sensor is called a CPTU. CPT probes with other sensors are also used.
