It is critical to ensure that the materials used during construction meet industry standards, not only to secure approvals but to ensure performance and life cycle maintenance meets expectations.

Our team can assist with improving the performance of infrastructure via thorough material testing capabilities and technologies. 

Our management and operating practices are accredited to the International Quality Management System (ISO 9001) and many of our laboratory services have ISO 17025 accreditation. In addition we have nationally recognised material specialists working in our team. 

Why should you test your materials?

The likelihood of sourcing non-standard materials in construction is high. The use of alternative, cheaper and non-standard products in New Zealand can lead to significant loss further down the projects life-cycle line. 


How do we test materials? 

Our research offices and laboratories across the country provides the specialist equipment and know-how to carry out specalist advisory and consultancy services for the following materials: 

Soils

Our comprehensive soil and aggregate testing laboratory offers a wide range of tests so that geotechnical and pavement engineers can define the engineering properties required to design pavements and foundations for a variety of structures. The testing ensures that the pavement and foundations perform as expected and meet the asset owners design life requirements. 

Bituminous materials

We have an extensive testing laboratory with experience in the assessment and testing of a wide range of bitumen-based materials. We perform the full suite of tests required by the NZTA in their M1 specification on roading bitumen's. We can also test asphaltic concrete to ensure it complies with NZTA's M10 specification including onsite removal of cores to determine density and compaction. 

Concrete

Concrete testing is carried out in accordance with a variety of New Zealand, Australian and other international standards to determine fresh or hardened concrete properties, concrete, stone and clay paver performance, and cement quality.

Structures

We operate a structural testing laboratory based around a range of loading, measurement and data logging equipment with the capability to test a variety of materials and components under simulated load. The laboratory has a strong floor that allows virtually any material or structure to be tested. Dynamic testing may be used to simulate seismic or cyclic loading using a range of servo-controlled test machines and actuators with capacities ranging from five tonnes to 200 tonnes. A shake table is used to test the earthquake resilience of a variety of materials and components. Static testing may be carried out on the strong floor using jacks and calibrated load cells or using a range of universal test machines with capacities between one tonne and 100 tonnes.

 

Other Services include:

  • Concrete durability assessments Materials testing and analysis 
  • Measurement devices and instrumentation
  • Resilience to natural hazards
  • Technical evaluation of new technologies 
  • Compliance testing against New Zealand or international standards and specifications
  • Instrumental calibration
