Earth Test is a NATA accredited laboratory


Earth Test is a NATA accredited construction materials testing laboratory that also offers a wastewater evaluation and design service.Earth-Test-Map.png

Based in Aherton, we service the far north from Townsville to Karumba to the tip of Cape York. We pride ourselves on being trained to the highest quality in all aspects of construction materials testing.

Earth Test was originally set up to specialise in house site investigation and wastewater design. We added a geotechnical drilling rig and now offer a full range of tests for soils, aggregates and concrete. We can also offer a broad range of knowledge to help our clients from hands on experience during the entire project from start to finish. From small domestic to large scale commercial projects including evaluations for sub-divisions - we have worked on the full range of projects.

Being completely independent, Earth Test can design a wastewater treatment system that meets all council requirements and the owners needs without unnecessary expense.

Our project experience includes...

Main Roads

  • Compaction testing of pavements
  • Gravel particle size distribution
  • Atterberg limits for placticity
  • Dynamic cone penetrometer tests

Australian road research board

In conjuction with the ARRB, Len Quinn evaluated new pavement cross-sections for improved drainage and compaction testing using a Clegg Hammer, Nuclear density meter and sand replacement method.

James Cook University (JCU)

As a Technical Officer at JCU, Len delivered training to undergraduate students in soil and concrete testing technology and testing methods. He also supported Post Graduate students with their thesis and faculty staff with a range of applied research.

This work was directly related to industry e.g. Unusual failure modes in Coal Stockpiles and to technology design and development e.g. Repeated load apparatus for pavement material testing

Ready Mix Laboratory ‘Bohle Quarry’

Len Quinn designed and build the first NATA accredited soils laboratory north of Brisbane. This lab provides quality control for all Holcim Quarry and Concrete products in North Queensland.

Quarry Sites and Systems

As a soil technician, Len has extensive experience in selecting quarry sites, examining potential for rock quality and quarry equipment specification to maximising the quality of product from the quarry source rock.
