Protective membranes welded to the inside of concrete sewer pipes can help prolong their lifespan.

What is a good concrete liner system for sewer repair?

There are many old sewerage systems in Australia, and keeping them well maintained is an ongoing concern of councils and utilities authorities across the country.

As with other types of major infrastructure, the proper functioning of the country's water and wastewater system is of critical importance – perhaps even more so given that it protects the health of millions of people as well as the environment.

Why concrete sewerage pipes need to be protected

Australia's advanced sewerage systems are among the best in the world. However, there are still many factors – some unexpected – that can cause deterioration over time.

Biogenic sulfide corrosion can be a serious issue affecting concrete and steel within wastewater environments. This bacteria-mediated process of corrosion involves the formation of hydrogen sulfide gas which is subsequently converted into sulfuric acid – a highly corrosive substance.

Australia's sewerage system is one of the best in the world, but it needs regular maintenance.Australia's sewerage system is one of the best in the world, but it needs regular maintenance.

The reality is that it is near impossible to keep chemicals that may degrade concrete out of sewage. That is why sewer protective lining systems have proven themselves to be invaluable.
