Manholes and other underground structures experience different kinds of corrosion.

Whether it's severe ground water infiltration, high levels of hydrogen sulphide (H2S) gasses, or a combination.

Add to this, budget constraints and specific life expectancy and you have to tailor the rehabilitation solution to match the combination of needs.

They all need to be addressed in their own specific way. One solution does not fit all.

The presentation will discuss, with real life examples, how each one of the different manhole rehabilitation systems can be used to meet specific needs.
