Understanding Manhole Linings: Applications, Benefits & Process |

what are manhole linings?

Manhole linings are a crucial component in the maintenance and protection of manholes, which serve as entry points to important infrastructure like sewers, stormwater systems, and utility pipelines. These linings provide protection against rust, leaks, and structural wear and tear, ensuring the long-term durability and lifespan of the manhole. This article will delve into the advantages, uses, and steps for applying coatings to manholes, highlighting the importance of proper coating application for optimal protection.

polyurea protective coatings

ArmorThane’s polyurea coatings are a cost-effective and long-lasting solution for manhole rehabilitation, sewer lining repair, and more. The coatings are the result of extensive research, development, and testing of polyurea chemistry. ArmorThane polyurea is a type of elastomer that can be sprayed directly onto surfaces to create a durable and flexible layer. It is a great option for both new installations and restoration projects when it comes to manhole linings. In this context, polyurea offers several advantages that we will explore in more detail below.

BENEFITS OF implementing armorthane POLYUREA

Manhole linings are crucial for keeping manholes fully functional without any downtime. It's important that you understand what makes our polyurea so superior to other protective coating options. Below are just a few of the many benefits you will get out of using ArmorThane manhole linings.

Corrosion Protection:

Polyurea forms a shield that safeguards the structure of the manhole against the impacts of moisture, wastewater and harsh chemicals. The remarkable strength of polyurea plays a role, in averting corrosion, leaks and structural decay thereby guaranteeing the durability and dependability of the manhole.

Cost Savings:

By protecting the manhole from corrosion, leaks, and structural deterioration, manhole linings reduce the need for extensive repairs or replacements. This leads to significant cost savings over time, as maintenance and replacement expenses are minimized.

Leak Prevention:

Over time, manholes may develop cracks, joints, or gaps that can lead to water infiltration, sewer leaks, and environmental contamination. Manhole linings seal these openings, effectively preventing leaks and reducing the risk of groundwater pollution.

Structural Enhancement:

Polyurea offers exceptional structural enhancement for manhole linings. Its unique properties make it an ideal choice for preserving and enhancing the functionality of manholes in urban infrastructure systems.

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.

why choose polyurea over traditional coatings

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.
