Density Testing

To allow comparison of the achieved field compaction with a laboratory reference density, it is necessary to be able to reliably determine the achieved field density and moisture content. The commonly used methods for assessing field bulk density is the nuclear density gauge (AS 1289.5.8.1), but moisture content usually is measured in the laboratory. Indirect measures of achieved compaction include penetrometer testing and test rolling using a water cart (or loaded truck) or smooth drum roller.

The Perth Sand Penetrometer (PSP) is often used to assess the density of  clean sands, with the number of blows required to drive a blunt ended rod into the sand taken as an indicator of the relative compaction of the sands.

The Dynamic Cone Penetrometer (DCP) provides a similar correlation for all soil types. 

In some circumstances visual appraisal (including test rolling, if appropriate), may override test results for relative compaction.

When carrying out earthwork supervision, the SITE Geotechnical team will perform and record the necessary testing for your project and undertake daily site visit records when undertaking level 1 supervision. Whether for a civil engineering or road construction project, building, infrastructure, or land development, our team can provide the thorough geotechnical investigations and detailed reports that you require.

Get In Touch

    Thank you for getting back to us so quickly, we really appreciate it. We are really excited to utilise option 5 as the location of our AGs are now shallower within our pavement and hopefully we will encounter no/minimal clashes with existing shallow services. Thank you again and we look forward to working with the team in the future.
    "I acknowledge your report and wish to congratulate you on a top quality submission complete with four options.... Look forward to speaking to you again”
    Laurie (Infrastructure Development Engineer)
    “Thank you for the soil report… my building surveyor likes the format of your soil reports very much and recommends your service to all concerned”
    “Many Thanks for a great report and value for money service”
    “Following our satisfaction with your work and soil report for our recently completed storeroom extension we would like you to forward a fee proposal for preparing a similar report on our new sports pavilion…”
