The Four Sewer Piping Materials and the Issues That Surround Them
16-08-2019

It is important for homeowners to be aware of the materials that their sewer piping is constructed from as it directly impacts the sewer repair process that can occur around your place of residence. Different materials encounter different problems throughout their lifecycle and repair services around these issues vary greatly.

 

We will be analysing the four materials commonly used in sewer pipes around residential areas and the problems they have been known to demonstrate.

 

Plastic PVC Pipes

The lightweight, resilient, and straightforward nature of this piping material contribute to it being the most pervasive within sewer lines. Should textbook installation be carried out, this material is known for its prolonged lifespan, averaging to 50-70 years, and for its strength and impenetrability from tree roots.

 

However, human-error and poor quality control procedures can take place during installation which can lead to imbalanced loading and stress to occur on the pipe, especially during earthquakes. Fortunately, sewer repair procedures for PVC pipes are relatively straightforward and non-invasive.

 

Clay Tile Pipe

The major benefit of clay tile pipe compared to their plastic counterparts are that they are inert, this is due to their classification as a ceramic and are made by heating, vitrifying, and glazing clay – alleviating rapid progression from harsh chemicals present in sewers. Because of these characteristics, clay tile pipe is an excellent option for gravity sewers as they are susceptible to root penetration – a detrimental issue that can result in laborious sewer repair and replacement of the entire pipe.

 

Cast Iron Pipe

These pipes, known for their excellent capability to withstand root invasion and earthquakes, featured prominently as a material in sewage systems dating back for over three centuries. However, since the advent of more technologically advanced materials such as ductile iron pipes, cast iron pipes are not as prominent as they once were. Major investments into sewer repair and maintenance frequently occurred surrounding this material, due to their proclivity to rust and corrode over time which caused collapsing at critical junctures.

 

Bituminised Fibre Pipe

Constructed from layers of wood fibres and viscoelastic polymer resin, this material of sewer pipes were eminent in older homes in rural areas due to being a low cost alternative to cast iron. However, these cheaper to manufacture materials come at a cost as bituminised piping gained a reputation for being an infamously weak and brittle sewer pipe material, with repair being extremely invasive as studier materials were used.

As you can see, it is extremely important that repair techniques for sewer piping be as non-invasive as possible to avoid disrupting municipalities and residential areas.
