A project to improve the electrical system in Toronto’s downtown core is currently ongoing and involves the construction of new cable chambers and concrete encased duct banks.
The contractor required a grouting solution to backfill underground casings and control ground water migration into the excavation site, adjacent to Lake Ontario’s shoreline.
Our experienced grouting specialists designed and successfully executed a cellular grouting program, using a mix of cement and foaming agent, suitable for this particular type of application and site conditions.
