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. Comments for this post are closed.
