Sumoline Manhole rehabilitation

Nuflow’s solution for
deteriorating manholes

Manhole Rehabilitation

As manholes reach the end of their lifespan, their deterioration can start to cause significant problems and put additional strain on sewer systems. With Nuflow’s manhole rehabilitation system, our technicians are able to repair cracks, seal against water intrusion, and create an ongoing resistance to H2S and microbial-induced corrosion (MIC).

Nuflow’s manhole rehabilitation products have been scientifically designed to bond to each other, locking on to the base and walls of the manhole to create a gas-tight seal.

With minimal environmental impact, Nuflow’s manhole rehabilitation solution is ideal for manholes located in residential backyards, roadways and amenity blocks.

Nuflow offers both a manhole base rehabilitation, or a full structural rehabilitation.

To rehabilitate the base of manholes, we use a combination of products to clean and repair the benching and channels. For a full manhole rehabilitation, we provide a structural manhole repair solution with a complete seal, right up to the manhole cover.

Exclusive Junction Repair Technology

Nuflow is the only Australian manufacturing company that can reline junctions in one complete process – saving time, money, and avoiding future costly failures. Unlike most other companies, we reline 1m – 1.2m past joints to help extend the life and strength of the junction.

We can extend from the lateral connection to the property boundary, giving peace of mind to asset owners and reducing risk of tree root intrusion and collapse.
