Civil Contractors

CMT testing Western Australia to solve your technical problems and material dilemmas

Working with Civil Contractors is our favourite because we love solving their technical problems and dilemmas with comprehensive CMT testing in Western Australia and the NT. In fact, we have been nicknamed the ‘Dirt Doctors’. We proudly feature this as a personalised plate on one of our vehicles!

As boring as dirt sounds, we love having a robust discussion about the techniques to apply to get the best compactive effort out of a non-conforming material, or how to blend a non-conforming material to increase the life expectancy of a road pavement.

If you’re a Civil Contractor, we can explain why materials behave the way they do, what to expect, and how to treat them to get the best from them. We love sharing our knowledge and building an ongoing relationship with our clients. Working all over the Territory, no matter where you are, we can get one of our experienced technicians out on-site, eliminating the frustration that comes with dealing with multiple suppliers and people. Unlike our competitors, being a Territory-owned-and-operated business, you can also be sure that money spent with HiQA stays in the Territory.

CMT Testing

Construction Materials Testing (CMT testing) is the process of testing construction materials used in new engineering projects or added to existing projects. The services involved in a comprehensive CMT process depend on the project, the land, and the scope of services.

Testing services can generally be divided into on-site testing and laboratory testing.

CMT on-site testing services take place on-site. Roadways, airports, utility projects, and building developments typically involve CMT processes carried out by certified professionals. In the field, construction materials (CMT) testing can involve:  

  • Soils  
  • Concrete/Asphalt  
  • Steel  
  • Masonry  
  • Timber  

During an on-site test, construction components, moisture, air content, and more are evaluated. We elevate this through visual inspection and/or non-destructive techniques. Steel structures, retaining walls, and soil foundations are perfect examples of construction evaluated during field testing. If test results are inconclusive, samples of various materials may be collected and sent off for further testing. 

Laboratory testing is recommended as the next phase of a comprehensive CMT regimen. Laboratory testing is typically performed on an as-needed basis. Common lab-tested construction materials include:  

  • Soil – Modified/Standard Proctor, Bearing Ratios, Classification Tests, Swell Testing, Compressive Strength Testing, pH Testing, Chloride/Sulfide Testing, Hydraulic Conductivity, Consolidation, Permeability Testing, Shear Testing, and more.  
  • Asphalt – Mix Evaluation, Stability, Flow, Bulk Specific Gravity, Gradation, Density (Marshall), and more.  
  • Masonry/Concrete – Flexural Strength Testing, Compression Strength Testing, Unit Weight, Tensile Testing, Absorption, Efflorescence Testing, Mix Design, Structural Masonry Testing, and more.
