Structus has international experience when it comes to post tensioning (PT). The benefits of post tensioned floors slabs are:
– Thinner slabs and longer spans therefore large column free spaces can be achieved (200mm thick flat slabs up to 8m spans)
– Significant reduction steel reinforcement (up to 80% reduction)
– Reduction in shrinkage cracks due to the post tensioning proving constant compression on the concrete
– On-grade slabs on expansive soils
Structus recently attended a seminar hosted by Concrete NZ called Design & Construction of Post-Tensioned Buildings. We have also had discussions with contractors in the local market, in which the benefits of going to post tensioning could mean more buildings are going to be constructed with this method.
Give us a call if you’d like to consider post tensioning on your next project.
