The Isaac laboratory is one of Canterbury’s most trusted; having provided independent testing and accredited site sampling to Isaac Construction and our wider industry for many years.

A number of organisations already partner with us to provide a one-stop shop for a number of onsite requirements, including core sampling, NDM and specific asphalt mix design solutions for various infrastructure projects. The advantage of having an in-house laboratory means you can expect a quicker turnaround when it comes to results too.

We also undertake IANZ tests as well as the investigation of new aggregates, bitumen and asphalt; helping us provide tomorrow’s solutions today and driving us faster towards sustainability. We also provide daily production testing for a number of other quarries too. We strive to constantly invest in new technology, recently purchasing a new gyratory compactor which has increased our ability to run more asphalt tests.

The Isaac laboratory has recently expanded its scope and is now able to conduct the following testing in addition to our existing services;

- NZS4402: 1986 Test 4.1.1 Standard Compaction (Proctor test)
- NZS4402: 1986 Test 4.1.2 Heavy Compaction (Modified Proctor test)
- NZS4402: 1986 Test 4.1.3 Vibrating Hammer test
