Nor-Cal Pipeline Services provides complete manhole rehabilitation solutions to extend the life of aging infrastructure and prevent infiltration, exfiltration, and structural failure.
Manhole Rehabilitation & Restoration Services
Why Manhole Rehabilitation Matters
Damaged manholes contribute to groundwater infiltration, system overflows, and premature deterioration. Our rehabilitation approach improves structural integrity and restores performance.
Maintenance holes and other sewer structures naturally deteriorate over time, creating risks that can compromise the integrity of the entire sanitary sewer system. These structures are built from various materials—including brick and concrete block—each with its own vulnerability to aging and structural failure.
Brick maintenance holes often lose grout as they age, allowing groundwater infiltration or causing brick collapse. Concrete manholes face a different threat: premature failure due to microbial-induced corrosion (MIC) caused by sewer gases such as hydrogen sulfide (H₂S).
Nor-Cal Pipeline Services provides long-lasting manhole rehabilitation using SewperCoat® by Kerneos, a 100% pure calcium aluminate cementitious coating. This protective lining creates a permanent bond to the structure, sealing it against corrosion, infiltration, and exfiltration. SewperCoat® is engineered to restore structural integrity, extend service life, and protect manhole systems for decades.
Our team is certified through both the Pipeline Assessment Certification Program (PACP) and the Manhole Assessment Certification Program (MACP), ensuring every rehabilitation project meets the highest industry standards.
