corroded cast iron pipes

Cast iron pipes are no longer the preferred material for sewer systems. They are prone to deterioration from handling sewage and wastewater daily. Pipe lining in Boston, MA can replace them with a durable, non-corrosive, and long-term solution.

Limitations Of Cast Iron Pipes


Cast iron pipes are susceptible to corrosion. All the exposure to sewage, chemicals, and its surrounding soil causes the pipes to rust and corrode from the inside out. This weakens the structural integrity of the pipes, leading to leaks, cracks, and eventual failure.

Scale Buildup

Cast iron pipes are also prone to scale buildup. This occurs when minerals in the water form deposits on the interior walls of the pipes. Scale buildup restricts water flow, reduces pipe capacity, and increases the risk of blockages and backups. CIPP pipe lining offers a solution by creating a smooth, seamless lining inside the existing pipes. This prevents scale buildup and restores optimal flow capacity.

Tree Root Intrusion

Tree roots are naturally drawn to sources of water and nutrients. Trees around your sewer system can infiltrate sewer pipes in search of water. Once inside the pipes, tree roots can cause blockages, leaks, and structural damage. Cast iron pipe lining seals off cracks and gaps in the pipes, preventing tree root intrusion and extending the lifespan of the sewer system.

Structural Degradation

The structural integrity of cast iron sewer pipes can degrade due to external factors. Soil movement, ground shifting, and heavy traffic above ground can further weaken cast iron with minor damages. This degradation can lead to misalignments, offsets, and collapses in the sewer line.

Sewer pipe lining reinforces existing cast iron pipes. It provides added strength and stability while replacing the pipes from within. Replacing them with noncorrosive and durable pipe lining prevents structural failure.
