Why Scarborough Homes Need Waterproofing
Ontario’s freeze-thaw cycles, spring snowmelt, and summer storms put constant pressure on Scarborough foundations. The clay and glacial till soils common in the area retain moisture and create hydrostatic pressure against basement walls. Proactive waterproofing protects structural integrity, indoor air quality, and property value.
