Rose Bay

The drainage in the video was in a very poor state, with the large root intrusion and cracking present in the VCP, it is clear that immediate repairs were needed to be carried out!


The video below shows that roots are also commonly found in PVC pipes. As you will see, ground movement can lead to cracking, allowing roots to find their way into the line. These roots were causing ongoing issues for the client for a very long time, in just one day - all the issues were fixed! Enjoy!

With root intrusion on nearly every joint of this sewerage line, major repairs needed to be carried out. Excavation was out of the option due to the line running out under a busy main road. A1ADT was able to carry out the work over a couple of days!

We are proud to annouce that during our visit to Hamilton Island AUS & NZ Conference we were, once again, given the honour of receiving 'Job of the Year' 2011. The William Bland Building, located in Macquarie St Sydney, was experiencing ongoing issues with flooding in their offices due to the corrosion of the existing cast iron stormwater stacks.

A1ADT was able to successfully carry out over 250 metres of relining over a 3 week period with minimal access available, all while businesses continued to operate! This is one success story that highlights A1ADT's ability to efficiently plan and operate all while maintaining minimal customer disruptions.

Following our recent recognition as one of the largest drain and pipe relining providers in Australia and New Zealand as per materials installed, we have recently also been rewarded 'Job of the Year' for 2009 at our latest international conference.

The job was unique because this was the first 225mm boundary trap that had been installed and we were able to carry out this work while the 30 storey apartment block was still in use. We created a flow-through bladder that bypassed the work being carried out.
