Restoring Structural Integrity: Cured-In-Place Lining of 100-Year-Old Cast Iron Pipe Infrastructure
The customer was experiencing recurring sanitary backups attributed to deteriorating cast iron piping located beneath a concrete patio.
The existing pipeline was first thoroughly cleaned using mechanical descaling equipment to remove debris, scale, and obstructions. This was followed by another CCTV inspection to assess pipe conditions, verify alignment, and identify any defects such as cracks, voids, or root intrusion. Once properly prepared, a NuFlow resin-saturated liner—engineered for structural renewal—was inserted into the host pipe using the pull-in-place method. The liner was then cured in place using ambient or UV light curing technology to form a new pipe within the existing infrastructure.
A trenchless rehabilitation approach was recommended to restore the structural integrity and performance of the 100-year-old piping system while minimizing disruption to the property. The proposed solution utilizes NuFlow cured-in-place pipelining for installation.
This method effectively eliminates infiltration and exfiltration, restores full flow capacity, and provides a long-term solution with design life exceeding 50 years. Additionally, the trenchless process avoids the need for excavation, preserving existing structures such as slabs, landscaping, and hardscapes, significantly reducing project duration, cost, and overall impact to the property.
