Water cutoff in a sewer rehabilitation project

Leak Sealing in Sewer Rehabilitation Project

Location: Markham, ON
Sector: Utilities
Category: Cement Grouting, Water Cut-off


We provided a specialized water cut-off solution for a municipal sewer maintenance project. The project required grouting from surface to repair leaks in a large diameter sewer pipe.

Our solution involved pumping a fast-curing cement plus sodium silicate grout mixture delivered through vertical injection pipes installed around the sewer.

This work required a customized grout plant with multiple pumps and flow meters.
