Manhole Waterproofing – the Full Scope

In a previous blog post, we talked about how Tenera's teams of experts come up with practical solutions for fixing and waterproofing flat roofs. Many years of experience allow us to customise plans for each project, considering the unique features of utility location to find the best solutions.


Importance of Waterproofing Manholes

Waterproofing manholes is crucial for maintaining the integrity and longevity of underground infrastructure systems. Manholes serve as access points to sewer lines, stormwater drains, and other utility conduits, making them susceptible to water ingress. Without proper waterproofing, groundwater infiltration can lead to structural deterioration, corrosion of metal components, and the infiltration of contaminants into the wastewater system. Additionally, water intrusion can cause soil erosion around the manhole, compromising its stability and posing safety risks. By implementing effective waterproofing measures, such as sealants and coatings, the risk of water damage and associated infrastructure failures can be significantly reduced, ensuring the reliability and functionality of the underground network for years to come.


Tenera’s Services

Tenera's services begin with a comprehensive site inspection to carefully document all identified issues at the onset of each repair project. The detailed report compiled by our inspectors forms the foundation for developing an applications design document, delineating the crucial scope of work and cost-effective solutions. This document specifies materials and various types of work required. Subsequently, Tenera adeptly manages the tendering process, awards the project, supervises the work, and ensures job completion, which may entail generating any required reports.


Full Scope of Repairs

Manhole waterproofing encompasses a comprehensive array of tasks to ensure the integrity and functionality of underground infrastructure. It begins with the meticulous removal of tree roots and incrustations that may compromise the structure's integrity. Next, crack repair becomes paramount, addressing any fissures that could serve as entry points for water infiltration. Patching and/or parging are then undertaken to reinforce weakened areas and restore the manhole's structural integrity. Cold joint waterproofing further fortifies the structure against water ingress at vulnerable points. Riser joint injection is employed to seal any gaps or joints, preventing water intrusion. Finally, a protective coating is applied to the interior surfaces, providing an additional layer of defense against corrosion and deterioration, thereby ensuring the long-term reliability of the manhole.


Adhering to Tenera’s work type and material specifications ensures lasting waterproofing results.
