Local knowledge

Where the Speed meets the Grand.

Cambridge is built where the Speed River joins the Grand, and it has history with high water. In May 1974 the Grand flooded downtown Galt, putting some streets under as much as six feet of water, and berms were built along both banks afterwards. The City still keeps a temporary flood wall it can put up when the river rises, most recently used in an emergency during an ice jam in February 2018, at the Concession Street Bridge.

Most basement leaks we see here have nothing to do with the river, though. They come from cracks, ageing walls, tired weeping tile and window wells that fill up in a storm, like the August 2016 storm that left basements flooded around the city. Older homes in Galt, Preston and Hespeler are the most likely to have stone foundations, which let water through as their mortar wears out.

The ground changes from street to street. The Cambridge area mixes glacial till with large sand and gravel deposits, so drainage on one lot can be very different from the next. We look at grading, downspouts and what's around your foundation before we recommend anything.

Questions

Cambridge questions, answered

Is there a Cambridge rebate for a backwater valve or sump pump?
Not that we've found. As of fall 2026 we haven't found a City of Cambridge or Region of Waterloo program that subsidizes backwater valves, sump pumps or downspout disconnection for homeowners, so we quote assuming you pay the full cost. If a program opens, we'll help you apply before any work starts.
Who's responsible for the sewer pipe to my house?
In Cambridge, the property owner is responsible for the water and sewer pipes from the property line into the home. If you've been told your sewer line needs work, the City asks you to check with its Building Division about whether a plumbing permit is needed.
Will waterproofing protect me if the river floods?
No, and anyone who says otherwise isn't being straight with you. River flooding is managed through the dikes, berms and the City's flood plans. What waterproofing stops is rain and groundwater getting through your foundation, which can happen anywhere in the city, river or not.
