We provide our clients with fast, detailed, and confidential industry specific testing from our NATA accredited modern geotechnical laboratory.

​

Our Brendale facility is fitted out with new equipment and a temperature-controlled laboratory which covers aggregate, soils dimensional stone specific testing and petrographic analysis.

​

The laboratory is managed by a professional team with over 40 years of combined experience in laboratory services.

​

Our scope of work includes a range of testing and sampling to AS, QTMR, ASTM, AS/NZS, EN and inhouse methods.
