Local Conditions in Scarborough
That Affects Basement Waterproofing
-
Older Homes With Aging Waterproofing Systems: Much of Scarborough was developed between the 1950s and 1970s, meaning many homes are now 50–70 years old. Foundations from this era often relied on basic damp-proofing instead of modern waterproofing membranes, which can deteriorate over time and allow groundwater to enter basements.
-
Highland Creek Watershed: Eastern Scarborough lies within the Highland Creek watershed, one of the most urbanized watersheds in the Toronto region. Extensive pavement and development cause rainwater to run off quickly during storms, increasing the risk of flooding and saturated soil around homes.
-
Clay-Heavy Soil: Many parts of Scarborough sit on clay-rich soils that hold moisture longer after rain. This can create hydrostatic pressure against basement walls and floors, forcing water through cracks or porous concrete if foundations are not properly waterproofed.
-
Aging Sewer and Stormwater Infrastructure: Much of Scarborough’s sewer and stormwater infrastructure was built decades ago. During major storms, these systems can become overwhelmed, which is why the City of Toronto has introduced the Basement Flooding Protection Program to upgrade drainage and reduce flooding risks.
