NEW ZEALAND’S LEADING
PROVIDER OF CONCRETE
POST-TENSIONING SOLUTIONS

Post tensioned concrete for any project

Contech offers advisory, design and construction services for structural and civil engineering projects of any size and scale. We can retrofit and strengthen weakened and damaged structures.

Our post-tensioning systems have many applications:

  • Cantilevered and incrementally launched bridges.
    Post tension systems can overcome access problems, minimise ground disruption, and be faster and less expensive to deliver than alternatives.
  • Post tensioned concrete slabs are joint-free, low maintenance and they look great.
    A post tensioned concrete slab is ideal for anywhere that needs a low-maintenance yet durable flooring solution. Examples include storage and distribution warehouses, retail stores, manufacturing facilities and heavy-duty pavements and load-out aprons.
  • Elevated concrete slabs.
    Elevated concrete slabs are commonly used in multi-storey buildings and car parks. Elevated post-tensioned slab construction allows pouring the entire structure on site, reducing the reliance on cranes.
  • PRESSSS and PRES-Lam structures for resilient buildings.
    Post-tensioning is a key part of designing resilient, low-damage buildings through the application of post-tensioning to allow the building to absorb moderate earthquake forces.
  • Water reservoirs.
    Post-tensioning systems in water reservoirs make them stronger and less prone to cracking when filled with water.
  • Concrete transfer beams within structures.
    This allows for increased span lengths, greater load carrying capacity, and reduced deflection.
  • Structures that require external post-tensioning solutions.
    Post-tensioning is a great solution to increase the capacity of bridges, buildings and reservoirs.

Post tensioned concrete design adds value to your project

There’s no such thing as an off-the-shelf solution in post tensioned concrete design. The Contech team looks to understand the goals and processes of consulting engineers and building owners, and share our expertise to get the best solution. 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. Our team share their knowledge to make 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.
  • Contech’s team of experts handle all design, CAD drawings, interface with precast, and racking in-house.
  • Our design and installation teams collaborate closely to proactively resolve any issues. This reduces additional costs arising during the construction phase.

Local and offshore partnerships bring innovation and experience

Over the years, Contech has developed deep relationships with leading players in the global construction and civil engineering sector. 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.
