New Zealand’s leading provider of concrete post-tensioning solutions.

BBR Contech offers advisory, design and construction services for structural and civil engineering projects of any size and scale, including retrofitting and strengthening weakened and damaged structures.


Our post-tensioning solutions have many applications:

  • Cantilevered and incrementally launched bridges.
  • Joint-free, low-maintenance concrete floors for storage and distribution warehouses, retail stores, manufacturing facilities and heavy-duty pavements and load-out aprons.
  • Elevated concrete slabs, such as those needed for multi-storey buildings and car parks.
  • Water reservoirs.
  • Concrete transfer beams within structures.
  • Structures that require external post-tensioning solutions.

How we add value to your project
Because there’s no such thing as an off-the-shelf solution, the BBR Contech team looks to understand the goals and processes of consultant engineers and building owners. Our experience in designing slabs to meet precise requirements means we can maximise utility while mitigating expensive risks. We’re more than happy to meet during the initial design and specification stages to help you develop a bespoke solution.

  • Full design and installation post-tensioning services are available from our Auckland, Wellington and Christchurch offices, making a post-tensioning floor configuration readily accessible and very cost-effective.
  • We work closely with building owners, contractors and designers to develop the optimum post-tensioning configuration for any floor.
  • All design, CAD drawings, interface with precast and racking are handled in-house by BBR Contech’s team of experts.
  • Seamless connection between our design and installation teams means any issues are pro-actively resolved before costs accrue during the construction phase.

Local and offshore partnerships bring innovation and experience
Over the years, BBR Contech has developed deep relationships with leading players in the global construction and civil engineering sector. Our joint venture with SRG Global enables our New Zealand team to draw on expertise from Australia and further abroad, to underpin the solutions we develop for elevated post-tensioned slabs and ground support.
