Grouting is preventative maintenance which can protect sewers from further infiltration, water level sags, holes, sink holes and more.
What is Grouting?
Grouting is the use of a chemical sealant to stop leaks and infiltration from coming into a pipe. Grout not only stops infiltration but is also effective to prevent erosion around the outside of the pipe.
This preventative opportunity is a much cheaper option than treating ground water and less risks of backup due to overwhelming pump stations.
The application of the grout depends on where the infiltration is coming from. Our grouting unit repairs leaks in laterals, mainline and manhole leaks with the ability to fix pipes up to 600mm in diameter. If roots are evident in a pipe then grouting may be needed.
When to Grout
If infiltrating water is coming into the pipe then the wastewater system would be treating unwanted ground water causing damage.
Lining, grouting and spot repair and grouting go hand in hand. Infiltration needs to be stopped before repair can be done. After a liner is installed and laterals are cut out or ‘reinstated’, grouting of that annular space needs to be done.
Cleaning and inspection of the lines are done. Data and videos are reviewed, any infiltration code or roots that are seen is analyzed. Information is sent to client and pricing is provided if requested.
