SPECIALIZED CONE PENETROMETERS

Seismic Cone (SCPTU)
combines the downhole seismic method and logging capabilities of the CPTU •- The SCPTU also collects shear (Vs) and compression (Vp) wave velocities • - From interval shear wave velocities and and the mass density (r ) of the soil layer, the dynamic shear modulus (Gmax) can be calculated Gmax = r Vs2 - The dynamic shear modulus is a key parameter for the analysis of dynamic loading from earthquakes, vibrating machine foundations, waves and wind

Resistivity Cone (RCPTU)
	combines soil resistivity measurements and logging capabilities of the CPTU •- The RCPTU also measures the bulk resistivity of the soil •- Resistivity measurements can be combined with CPTU data to generate a continuous profile of contaminant plumes in groundwater •- Estimates of groundwater rate and direction of flow can also be calculated from RCPTU data •- Identification of the lateral and vertical extent of contamination allows for the rapid implementation of a remediation program

Ultra Violet Induced Fluorescence Cone (UVIF-CPTU)
combines fluorescence detection of contaminants and logging capabilities of the CPTU - UVIF module directs ultraviolet light into the surrounding soil and groundwater, causing hydrocarbon contaminants to fluoresce - At each test location a vertical profile of contaminant location and soil stratigraphy are generated in real-time - This information allows for on-site assessment resulting in optimization of the site investigation

Gamma Cone (GCPTU)
	combines detection of gamma radiation to enhance logging capabilities of the CPTU and to locate radioactive waste •- The GCPT utilizes the natural gamma radiation found in all soils to provide an enhanced soil stratigraphy interpretation •- In addition the GCPT can be used to locate radioactive contamination based on a gross gamma ray count •- The GCPT uses direct push technology resulting in no cuttings being brought to the surface, minimizing worker exposure
