Cone Penetration Test (CPT)
The Cone Penetration Test (CPT) is a method used to determine the Geo-technical engineering properties of soils. A CPT device consists in a cylindrical probe with a cone-shaped tip with different sensors that allow a real time continuous measurement of soil strength and characteristics by pushing it into the ground at a speed of 2 cm/s. The typical CPT probe measures the stress on the tip, the sleeve friction and the porewater pressure. This device is also equipped with a Geo-phone in order to be able to perform shear wave velocity measurements. The data is normally read by a field computer that displays it real-time and stores it at regular depth intervals. BUET-JIDPUS has this testing facility with maxium penetrating capacity of 45 meter. We do this testing anywhere in Bangladesh subject to testing fees.
Ground Penetrating Radar (GPR)
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks. There is a range of antennas for different types of application. We have Five (05) antenna: 100 MHz, 200 MHz, 400 MHz, 900 MHz and 1600 MHz.
