About Installing a Manhole to Manhole Sewer Lining
Installing a manhole to manhole sewer lining may be necessary in various situations including ground water infiltration or other circumstances that lead to manhole deterioration. Typical linings are made from concrete or an epoxy coating. These linings are excellent for preventing any leaks or damages to the manhole and rehabilitating it.
The epoxy liners used for manhole to manhole sewer linings can also be used for steel tanks, concrete tanks, waste water sludge tanks, metering chambers, sanitary sewer lift stations, and storm water catch basins.
Two component linings
Two component linings consist of a 100% solid epoxy corrosion barrier coating and a high strength restoration mortar. The mortar is shot onto a deteriorated manhole substrate and the epoxy coating is applied while the mortar is still soft. This creates a corrosion resistant continuous surface that is free of defects and results in adequate restorations in many cases.
Depending on the environment, a particular sewer lining may work better than others. Some types of manhole to manhole sewer linings are better on wet surfaces while others are better on drier surfaces. It is important to note which environment you are dealing with so you can be sure that the linings will react well, and to also work with a company that has experience dealing with installing manhole linings.
What components and tools are involved?
Several steps are required in order to install a manhole to manhole sewer lining, and as a result there are a lot of equipment and tools to keep track of. It is very important that a professional knows how to use these tools as well to ensure that the manhole lining is properly installed.
Heavy-duty hole saw attachment- This tool cuts through asphalt, concrete, and rock. This very powerful tool is often required with manhole rehabilitation projects. Safety procedures are essential when using a heavy-duty hole saw attachment.
Cleaning nozzle – The cleaning nozzle is a very useful component in a manhole rehabilitation project. These nozzles can rotate a full 365 degrees, allowing the nozzle to do most of the work.
There are several other tools involved, and the specific tools used depend on the scope of the project and other factors.
Be sure to work with an experienced company
Installing a manhole lining can be dangerous for those who are untrained, so it is essential to work with a company that takes the safety precautions and uses the appropriate tools. Manhole to manhole sewer linings require an utmost attention to detail to ensure that they are properly rehabilitated. Be sure that you hire a company that has experience with manhole rehabilitation projects and one that understand the latest safety requirements.
With the right company, a manhole can be completely rehabilitated to ensure that there are no cracks, defects, or anything else that could compromise the structure.
