Legion Drilling (Formally Numac) is Australia's leading provider of site assessment and remediation options for the contaminated land, infrastructure and mining industries. Our You Tube channel will be used as a means of communicating best practice, new technology and interesting case studies across environmental and geotechnical investigations. As a drilling and remediation contractor we have offices in Sydney, Brisbane and Townsville Australia. We are specialist sonic drilling, environmental and Geotechnical drillers. Legion have specialist CPTu, Vane Shear and DMT equipment for in-situ geotechnical investigations.
As contractors, we do not endorse any particular method to derive soil density (or other parameters), but you can find some commonly used formulas in Professor Paul W. Mayne's works. Another option would be to use DMT readings as an additional line of evidence complementing the Vs measurements.
@@fourfunkybass Sorry I missed this one. Using the true interval method for Vp is challenging due to the high velocity of p-waves, but it isn't unfeasible. This option is not implemented in the current version of SDMTPro, but hopefully we will see it incorporated in the future. Thanks, Jonas
