UNDERSTANDING MANHOLE LININGS:
APPLICATIONS, BENEFITS & PROCESS
WHAT ARE MANHOLE LININGS?
Manhole linings are essential components in the maintenance and preservation of manholes, which serve as access points to underground infrastructure systems such as sewers, stormwater drainage networks, and utility pipelines. These linings provide a protective barrier against corrosion, leaks, and structural deterioration, ensuring the integrity and longevity of the manhole. In this blog post, we will delve into the benefits, applications, and the process involved in the application of manhole coatings.
POLYUREA PROTECTIVE COATINGS:
Polyurea is a spray-applied elastomer that forms a seamless, flexible, and durable membrane when applied to various surfaces. When it comes to manhole linings, polyurea offers numerous advantages that make it the perfect choice for both new installations and rehabilitation projects. Next, we will explore some of the structural enhancements that polyurea provides for manhole linings.

Benefits of POLYUREA FOR Manhole Linings:
Manhole linings play a critical role in maintaining the integrity and functionality of manholes, which are essential components of underground infrastructure systems. One of the most effective materials used for manhole linings is polyurea, a versatile and durable coating that offers numerous benefits. In this blog post, we will explore the advantages of using polyurea for manhole linings.
Trenchless Manhole Linings vs. Replacement
Industrial facilities and municipalities have found trenchless manhole lining methods to be a trustworthy and effective solution for restoring the integrity of their infrastructures. Compared to manhole replacement, manhole lining offers several advantages that make it a more sensible choice from a business perspective.
- More Cost Effective: One of the primary reasons why manhole lining is preferred over replacement is the cost savings it provides. By opting for relining, the need for initial digging and the subsequent expense of rebuilding is eliminated. This significantly reduces the overall cost of the project, making it a more financially viable option. Saving both in terms of excavation and restoration makes lining an attractive choice for manhole maintenance.
- Minimul Disruption: Trenchless lining allows municipalities and facilities to maintain their focus on their core business activities. Unlike replacement, which requires shutting down operations to accommodate large construction equipment and deal with extensive excavations, relining can be carried out without any disruption. Rehabilitation crews, with their specialized equipment and techniques, can complete projects within a relatively short time frame of 10 to 12 hours. This minimal downtime ensures that daily operations can continue uninterrupted, maximizing productivity and minimizing potential revenue losses.
- Similar Lifespan: Polyurea manhole lining is a modern and innovative approach to manhole rehabilitation. It involves applying a specially formulated polyurea coating to the existing manhole structure, effectively creating a resilient, seamless, and watertight protective barrier. The polyurea lining is sprayed onto the manhole walls, efficiently adhering to any surface irregularities and forming a durable, flexible, and corrosion-resistant layer. The key advantage of polyurea manhole lining is its exceptionally long lifespan. While the durability of traditional manhole materials, such as brick or concrete, may deteriorate after several decades, polyurea linings can last for 50 years or more. This extended lifespan significantly reduces maintenance costs and the need for regular repairs or replacements.
CONCLUSION
Polyurea manhole lining provides a cost-effective and durable solution for manhole rehabilitation. Its extended lifespan, chemical resistance, structural reinforcement, seamless application, and efficient installation make it a superior alternative to traditional manhole replacement methods. By opting for polyurea lining, utility companies, municipalities, and engineering firms can ensure the long-term integrity and functionality of manholes while minimizing maintenance expenses.
