corroded cast iron piping

Cast iron pipes are commonly used in older homes. However, while cast iron is a great choice for sewer systems, it’s also prone to a variety of problems that newer pipes are not. At NGI Trenchless Pipe & Sewer Repair we specialize in trenchless pipe lining in Atlanta, GA, and often encounter cast iron pipes plagued with the following problems:


Cast iron is very strong, making it an excellent choice for underground pipes such as residential water supply pipes and the main waste lines from your house to the city sewer line. However, this material is prone to corrosion and scouring over time. The flow of waste in your pipes can lead to hydrogen sulfide gas and sulfuric acid. This can erode the cast iron over time, significantly reducing its lifespan. This issue is further worsened by the use of chemical cleaners. To keep your pipes in great working condition, consider our professional pipe lining service.


Cracks and leaks can occur on cast iron pipes due to the freeze-thaw cycle during winter. While these problems may not be evident right away, they become a big problem after years of temperature changes. To protect your pipes, be sure to insulate them before winter. If you notice the signs of a leaking pipe, schedule cast iron pipe lining right away. This trenchless solution will seal any cracks in your pipe and protect it from freezing while extending its lifespan.

Foundation Cracks

As cast iron pipes deteriorate, they allow water to leak into your home’s foundation causing cracks. When not dealt with properly, this can lead to costly and extensive water damage, mold, mildew growth, and a variety of other problems. At the first sign of pipe damage, which can include slow drains, gurgling toilets, and a foul smell in your home, contact your local plumber for sewer pipe lining.
