Our focus for water and waste water clients is using modern ground improvement and in situ testing methods to reduce construction timeframes, lower construction costs, improve quality, reduce risk and reduce your environmental footprint.

Situations include:

  • Water pipelines
  • Drainage and sewers
  • Waste water treatment
  • Dams and reservoirs
  • Access tracks
  • Roads (Sealed and Unsealed)
  • Slope stability

Insitutek don’t just provide technical solutions – we inspire progress. In an industry often bound by convention, we lead with innovation, empowering you to break new ground across Australia, New Zealand and the Pacific.

We engage deeply, forging partnerships that elevate businesses and challenge the status quo. We envision a smarter, more resilient future for civil construction – where technology, expertise, and collaboration drive lasting impact.

Excel – not just in your projects, but in shaping a stronger industry and a better society.

Typical conversations with asset owners, civil engineering consultants and contractors are around answering questions like:

  1. How to assess compaction at all stages for trenching and trench backfill
  2. How to reduce time between testing and getting results – close to real time feedback on performance with project / stakeholder wide visibility
  3. How to increase compaction uniformity
  4. How to convert an uncontrolled fill site into engineered fill site, without remove and replace
  5. How to accelerate settlement or minimise differential settlement

What questions are you looking to answer? We’d love to hear from you.
