We pride ourselves on our ability to develop new test methodologies and carry out non-routine tests

WSP Opus Research offers materials testing and analysis services for a wide range of engineering construction materials.

We are accredited by International Accreditation New Zealand to ISO 17025 for many of those tests. Whether laboratory-based or on-site, this testing provides the information required to carry out specialist advisory and consultancy services.

Our materials testing includes:

Our comprehensive soil testing laboratory offers a wide range of tests, primarily so that geotechnical and pavement engineers can define the engineering properties required to design foundations for a variety of structures.

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 NZTA in their M1 specification on roadingbitumens. We can also test asphaltic concrete to ensure it complies with NZTA’s M10 specification including on-site removal of cores to determine density and compaction.

Our testing ensures roading applications meet the relevant NZTA specifications. We are also equipped to carry out repeat load triaxial testing of pavement materials, as well as polished stone value testing.

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.

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.
