NZGCL Updates

Watch this space for NZGCL and Industry updates

NZGCL are proud to announce that we now offer our clients the peace of mind provided by Nuclear Density Meter (NDM) Testing. The benefit of using a Nuclear Density Meter is a well-recognised, industry standard when it comes to compaction of gravel subgrades.


The NDM produces accurate data on degree of saturation, compaction percentage, and air void percentage in minutes. The NDM works by emitting radioactivity into the ground through either Direct Transmission or Surface (Back-Scatter) Testing and measuring the attenuation of energy within the ground.

Increasingly, NDM testing is becoming a requirement within construction monitoring because of its accuracy, portability, speed and non-destructive nature. 


NZ Geotechnical Consultants are here to ensure that the correct level of design is undertaken during any new build, no matter how big or small. We have the capabilities of producing qualitative and quantitative liquefaction assessments and can ensure that any new build is done to the required local authorities standards.

We are happy to discuss how we can assist in helping you with any future developments you are looking into. Feel free to contact us through e-mail ( or our offices directly on 03 390 5775.
