## Spiral Wound Pipe is the latest innovation in pipeline and culvert rehabilitation.



 

 

 



Using DiaFit™ ‘close fit’ technology, a new profile is initially wound into the existing pipe at a smaller diameter, and expanded out to make a new pipe which is in close contact with the existing pipe.





 

 



#### Applications for Spiral Wound Pipe

  
› **Wastewater mains:** Relining of wastewater mains from 150mm to 1000mm with no or minimal disruption to surrounding rehabilitation area.  
› **Stormwater:** Relining of stormwater mains from 150mm to 1000mm with limited disruption to the surrounding area. Ideal for road crossings and culvert rehabilitation.  
› **Rehabilitation of circular access chambers:** Rehabilitation of severely corroded circular access chambers without having to remove existing structure.  
› **Road culverts:** Relining of road culverts from 150mm to 1000mm with limited disruption to the surrounding area. Ideal for relining corrugated iron and concrete culverts.
